Student Guide to Writing a Chemistry Essay

Every thing around us contains specific materials and substances. Even people consist of particular substances that originate, evolve, and disappear in the eternal cycle of life. The science dealing with these transformations and examining the composition of everything on earth is chemistry.

That’s why chemistry is one of the fundamental sciences that enjoys unending popularity among thousands of enthusiastic students. Many of them want to work in the medical sphere, creating new medications and saving humanity from chronic illnesses. The others want to develop new cosmetics to help women preserve their beauty and vitality. The meals industry, automotive industry, aerospace companies – nobody can perform without chemistry. Thus, learners studying this subject have to master many rules, formulas, and chemical processes to provide value through their knowledge and skills.

Demonstrably, Chemistry just isn't everyone’s cup of tea. By taking a look at Human Resources school essay examples, for instance, you will get a misconception that writing an essay is simple and manageable. Still, Chemistry is definitely an exact science that doesn’t stand guesswork and creativity. Thus, you ought to keep specific rules, theories, and formulas in mind when writing it.

Should you feel confused and unsure about how precisely your Chemistry assignment must certanly be written, it’s not a good idea to submit a mediocre or off-topic paper to your professor. Your grades are too crucial that you leave them to chance and risk your GPA.

Therefore you can always get in touch with a seasoned Chemistry writer to get a top-notch assignment completed in hours. We have a sizable team of such experts on standby 24/7, willing to give a helping hand to any or all students seeking academic support from pros.

Chemistry Essay Format

Over all, the Chemistry format doesn’t differ that much from that of essays on any other subject. The critical point you will need to remember is that exact sciences change from the humanities. Thus, you cannot have a Human Resources school essay or Human Resources management essay and use them as templates for writing about Chemistry.

This subject has its specific requirements, whilst the structure remains pretty universal. Every essay should include these parts.

An Introduction

This part of an essay traditionally explains the general context of the research and provides the readers an initial notion of what the student really wants to examine. It poses the study question or challenges the readers with a specific research problem, hence focusing their attention on the quest for solutions.

A Body

The human body of a chemistry paper should introduce the readers to all relevant terminology and supply solid argumentation from the author’s point of view. It should dedicate one paragraph to one argument, thus giving a clear, logical flow to boost the readers’ comprehension.

A Conclusion

The last section of a Chemistry paper should be specialized in a brief summary of the information and a broader inference to the study’s significance for the broader chemistry area.

Hence, by third , format, it is possible to quickly complete any Chemistry work just how your professor wants it to be achieved.

Example #1: Nickel manufacture, recycle and its Environmental Impacts

Article 1

Nickel occurs naturally as oxides, silicates and sulphides. It's strong, lustrous and silvery white in color. Nickel sulfide processing is mainly employed for treating nickel ores , involving concentration, smelting and refining (Environment Australia, 1999). First, Nickel from sulphide ore is separated using froth flotation and magnetic process. The product obtained is further processed using sherritـGordon process. The sulphide ore can be treated with hydrogen where they are volatized in the kiln. It's then reacted with carbon monoxide at a temperature of about 60° C forming Nickel Carbonyl gas which decomposes on top of the Nickel pellet until they reach the specified size (Gold ore crusher, n. d. ).
Approximately four tonnes of nickel scraps are collected annually and recycled. The scrap is metal scrap from machinery, equipment and consumer goods. All the recycled Nickel is in the shape of steel scrap, batteries, bronzes, chemical leachates, liquor, dust, catalyst and coinage. These scraps are separated from other parts, for instance , assembled nickel which is then processed to materials of similar composition, therefore , used as new services.
Nickel is released into the environment by waste incinerator and power plants. It can also penetrate into the surface water included in waste water. When nickel compounds are released in the environment they're adsorbed to sediments hence becoming immobile. In acidic soil nickel is more mobile, consequently , it rinse out the bottom water. High concentration of nickel in sandy soil damages plants and diminishes the growth rate of algae on surface water. It can also cause cancer in animal when it exceeds the set standard concentration. Therefore , there's need to regulate nickel uses, according to its physical and chemical faculties. There should be regulations in order to protect workers along with other members of the public on the possible effect on their health. More over, the environment ought to be protected by the introduction of the emission levels (Environment Australia, 1999).

Article 2

What i learnt is Nickel has become extremely important recently, as a result of increasing industrial and commercial importance. Furthermore, due to its exemplary properties including strength at higher temperatures, ductility and corrosion resistance, it is used as a raw material to make products and services. This information was very important because I learned that nickel can be reused again, for that reason I should always preserve the old batteries and other nickel containing scraps for recycling. However , Nickel may cause environmental effect including health and safety effects. Therefore , I ought to take precautions when handling nickel product due to its toxicity.
The situation encountered while working in friends was that there was argument about how the job would be performed. It took a lot of time to pick how to perform the task. There have been different a few ideas whether the members should perform the assignment together or individually. Once we finally formalised the meeting, each member was assigned a task to do.
Hine (2000) implies that sharing discussion helps in transforming what sort of person reflects. Group work helped us to have broader ideas since tasks were shared as well as good leadership leads to very good results. Being in team work facilitated learning and enhanced my understanding on the subject. In addition team work experience helped me to understand my strengths and weakness in a team.

Example #2: Microwave Organic Synthesis

Institution:
Microwave Organic Synthesis
Abstract

For the past few decades, Electromagnetic microwave radiation has been trusted to provide heat for the formation of organics. The technology uses two main basic mechanisms; conduction and dipolar polarization. The technique provides a simple, fast, efficient and probably the most economical method of synthesizing organic molecules, which includes seen chemists shift from the traditional heating methods. This short article focuses on the generation of a microwave, as well as its importance in organic synthesis.

Introduction

A microwave is really a form of electromagnetic energy. The usage of microwave assisted organic synthesis technique has made the building of small molecules fast, rendering it a valuable tool that accelerates the discovery and development of drugs. Unlike other styles of radiation such as gamma and X-rays, microwave energy does not alter the compound’s molecular structure because of its nonionizing thermal activation. The heating effect is really as a result of dielectric polarization of the molecules. When the molecules are irradiated with microwaves, they get aligned with the applied electric field. The electric field keeps on changing rapidly, forcing the particles to realign constantly with the changing field, and in the process, energy is absorbed. The dielectric constant determines the ability of a compound to convert the microwave energy in to heat energy. The higher the dielectric constant, the rapid the heating process (E. Karthikeyan, 2011).

Microwave Heating

Microwave heating uses the electromagnetic transformation ability of some solids and liquids that transform rays into heat that drives the chemical reactions. This system is important for reactions that aren't suitable for the traditional heating.
Features of Microwave heating over the old-fashioned heating:

  • Increased speed
  • High efficiency
  • Reduced side reactions
  • High purity in the final product
  • Improved reproducibility
  • Reduced heat loss to the environment
  • Reduced wastage of the reaction vessel
  • Economical
  • Green Technologies

Solvents that are utilized in chemical synthesis are environmentally unfriendly once they are disposed. The microwave irradiation technology has over come this problem considering that the technique enables performing of reactions with no use of solvents. In conjunction with mineral-supported catalyzed reactions, the microwave irradiation has provided a clean chemical process with several advantages.

Dry media Reactions

There's been increased campaign for usage of environmentally friendly reagents and procedures. The microwave heating completes various reactions under solvent-free conditions on solid supports.

Microwave Synthesis

Microwave heating of organic compounds ha s eliminated the employment fire in synthetic chemistry that has generated ‘dry media’ reactions. The technology has additionally been exploited other related fields such as for instance synthesis of polymers, biochemical processes, nanotechnology and material science.

Microwave Synthesis on Solid Supports

Microwave heating is employed in performing ‘dry media’ reactions on solid supports. This is demonstrated in transformations such as condensation, protection, de-protection, oxidation and reduction reactions. A variety of industrial compounds and intermediates have decided by this clean, solvent-free approach. The organic compounds in these reactions absorb microwaves, and the solid support restricts their transmission (E. Karthikeyan, 2011).

Other Applications

Industrial applications of microwave heating process include; drying of pharmaceutical powders, pasteurization of foods, preparation of hydrogen cyanide and chlorination plants. Other exploitations of the of microwave heating include creation of improved crystallinity in intercalation compounds, production of organometallic compounds and polymer curing (E. Karthikeyan, 2011).

Summary of this article “Preparation and Characterization of Ceria Nanospheres by Microwave-Hydrothermal Method”

Introduction

Inside their experimental research “Preparation and characterization of ceria nanospheres by microwave-hydrothermal method, ” Santos and his colleagues (Santos et al., 2008) outline the microwave-hydrothermal method that enables the forming of cerium compounds at faster rates and at paid off temperatures. In line with the authors, a nanocrystalline CeO2 powder is employed as nanomaterial in catalysts, optical devices, polishing materials, and oxygen sensors, among other applications (Santos et al., 2008). In addition , they assert other methods have now been developed for the synthesis of the ultra-fine CeO2 powder, and so they include co-precipitation, organometallic decomposition, conventional hydrothermal, flow method, and their newly developed microwave-hydrothermal practices. In their method, they have used ammonium hydroxide (NH4OH), (NH4)2Ce(NO3)6, and a surfactant (PEG) to synthesize ultra-fine CeO2. CeO2 powder produced by microwave-hydrothermal method has narrow size distribution with a uniform spherical morphology.

Experimental

In this method, they dissolved (NH4)2Ce(NO3)6 and PEG in water, then added NH4OH until a pH 9 was obtained. The resultant solution transferred in to an autoclave and heated in a domestic microwave at 130oC for 20 minutes. The CeO2 powder obtained was washed with deionized water and subsequently dried at 80oC. The dried powder was further treated by calcination at 500oC at different periods of 1, 2, and 4h. The fully treated particles were analyzed by X-ray powder because of its characteristics. They used Scherrer equation (d=kλ/βcosθ) to determine the crystallite size of CeO2. The morphology of CeO2 particles was seen as a field-emission gun (FEG/STEM mode). A Netzsch-409 STA was used to investigate TG-DTA. They further used a Bruker Equinox-55 instrument to record the FT-IR spectra. Additionally , Roman spectra were recorded with Bruker RFS-100/S Raman spectrometer. In addition they used YAG laser concerning provide excitation for the experiment with its power maintains at 150 mW.

Results and discussions

The curves in Fig. 1 show the TG-DTA analyses of ceria powder. TG curves show a fat loss of about 11 %, which will show hydration has brought place. The mass loss is as a direct result decomposition of Ce(OH)3 (9. 95%) or Ce(OH)4/CeO2. 2H2O (17. 3%), which leads to partial hydration of ceria phases. Only 90% of weight loss does occur at 500oC. However , 650oC may be required for a complete dehydration. Additionally , DTA curve indicates an endothermic fat loss at 86oC. The endothermic weight loss could be because of water absorbed by ceria powder. An exothermic peak between 270-350oC correlates to weight loss as a result of crystallization of an amorphous phase. Fig. 2 shows the traits of calcined ceria powder. The patterns were uniform across all conditions in the experiment. The peaks in the figure really are a pure cubicflourite structure of CeO2. Furthermore, the intensive diffraction peak is at 2θ=28. 660° via [111] lattice plane of fcc CeO2. The ceria powders are of smaller sizes as indicated by the broadening of the peaks. Following the calcination, XRD peaks became sharper eventually while FWHM reduced; an illustration the calcination process accelerates the crystallinity of CeO2. According to them, the calcination temperature further affects crystalline sizes of ceria powder. The authors agreed that after all conditions for synthesis of CeO2 are met, particle agglomeration due to van der Waal’s forces contributes to the formation of ultra-fine CeO2 particles.

Fig. 4 provides Raman and FTIR spectral characteristics of CeO2 powder sample. In line with the authors, the high intense band noticed in the sample corresponds to the oxygen-hydrogen and hydrogen bonds in the water molecules within the crystals. The presence of residual water and the hydroxyl group don't depend on the synthesis method. As a result, they've been present in any ceria powder and expunged by heat application treatment. Furthermore, the synthesis of hydrated ceria powder (CeO2. nH2O) involves the formation of complexes through the hydroxylation and deprotonation of metal ions.

Conclusions

In conclusions, the authors report a simple microwave-hydrothermal method to synthesize a pure CeO2 at 130oC for 20 minutes. They also figured the methods not just save time and apply low temperature, but it also enables the get a handle on of morphological and structural properties. Additionally they confirmed the material can be utilized as nanomaterial in several fields such as catalyst and electrical materials.

Example #4: Summary, Synthesis of ZnO nanoparticles for microwave-induced rapid catalytic decplorization of congo red dye.

Zuas, O., Budiman H. and Hamin, N. originally published in High level Material Letters
2013 ( 4 (0) pp 662-667

This informative article is concerned with the problem of finding types of rapidly removing dye from waste water on an industrial scale.

This article begins by describing the experiment setup by researchers in the Indonesian Institute of Science when seeking a solution to the global problem among industrialised nations, and in particular among companies who use dyes such as congo red within their industrial processes and who then have to remove this dye in the most suitable way possible, and taking into account that needs to be achieved before the dye is released into the nearby water sources, where its presence is indeed harmful.

During the time of this experiment the removal of industrial dye from waste water was already possible using catalytic oxidation practices, as these researchers concede, citing six instances where this was attempted. The thinking behind this particular research was that it seemed likely that by combining methods already in use with microwave technology the results might be improved.

An experiment was designed after which set up by these researchers in which the synthesis of nanoparticles was achieved using co-precipitation and then calcining for 4 hours at 500C. Resulting data showed well-formed crystals with a top degree of purity. The crystals were then tested for decolorization of the dye by using microwave irradiation. After having a short time the outcome were that in 90. 63 rate of efficiency the dye was decolorised under particular conditions as specified in the article. The researchers were concerned with the main concentration of the particular dye, the amount of time and the dosage of the catalysts. It absolutely was felt by the researchers that since the catalytic effect was obvious it must certanly be that when the ZnO nanoparticles met the microwave technology this produced a synergistic effect in decolorizing the dye with a high degradation rate achieved quite rapidly. This would signify such technology is usable as an alternative method when wanting to remove industrial dyes from waste water, and so working with relative ease with a world-wide problem, in that water is being polluted by the use of dyes in industry. This isn’t just about the coloring of water, nevertheless the fact that when these dyes are present it's a negative effect upon aquatic ecosystems, the human populations which are based upon them. There was therefore a need to alleviate this problem, preferably in a way that is straightforward to set up, and which is both effective and cost efficient. There's also the fact that the industrial organizations involved have a responsibility to the wider world, and in this instance in particular to those who utilise the water into which their used dye materials are dispersed, whether as who count on the water, but also to the many kinds of life within the water which might be adversely affected if dyes exist in quantity.

Therefore a number of attempts, cited by these authors, have attemptedto find viable solutions to this global issue of the industrial age. The authors describe in detail specific things like the reagents used; the formation of ZnO nano-particles; the characterization of the synthesized ZnO nan-particles and the catalytic evaluation of the synthesized ZnO nano-particles. The article described a number of other techniques which have been tried to achieve similar results. Included in these are catalytic wet oxidation using modified Y zeolite as a catalyst, as described by Kondru et al in 2009. Also mentioned is photo catalysis, as described by Erdemoglu et al in 2008 and sonocatalysis as described by Wang et al (2008), in addition to methods like the biological ones, using fungi to eliminate these dyes in waste water. ( Battacharya et al, 2011). If left alone the dyes undergo biological changes when in a watery environment and this includes using up oxygen dissolved in the water, so decreasing the degrees of dissolved oxygen and depriving creatures which may use this oxygen, so reducing numbers and types of biodiversity in particular surroundings. The fact that so many other attempts have been designed to come up with a viable solution to the issue of dye polluting the water supply after industrial usage suggests not only the wide spread issues caused to the water systems, but additionally that those methods already tried were non-e of these completely effective.

The outcome of their particular experiment using microwaves are described in great detail, including things like the diffraction peaks of the crystals created; the evaluation of the microwaves of the synthesized ZnO nano-particles; the consequence of the first concentration of the congo red dye used and the effect of the ZnO dosages used followed by the results of various times tried, so this was a very complex experiment, or rather a number of similar experiments with numerous possible variables and so a number of results. So they really were comparing the decolorization under several different treatment processes.

The authors concluded, having completed all these experiments and having carefully evaluated the results, that the experiments showed that the use of microwave technology was linked to an activity whereby the usage of synthesized ZnO nano-particles was enhanced when used in aqueous solutions to remove congo red dye. They see this as a potentially possible method to ease the pollution caused by today's practice of releasing industrial dyes in to the water supply as contaminated waste water. It also gives one more selection of possible treatment available to environmentalists as they seek to combat the adverse results of industrialisation upon aquatic environments in a number of situations all over the world.
