The Behavior of Gases: Molar Mass of a Vapor

The experiment evaluates the density of the vapors for a volatile fluid to figure out its molar mass. The result was made possible by heating and cooling the water, which is 0.16kg, within a flask, gathering the resulting vapor inside, and evacuating the flask. The vapor’s minimum density was calculated by measuring the total mass ... Read More

Kinetics of Solvolysis: A Study of the Nucleophilic Substitution Reaction II

Introduction Solvolysis refers to an SN1/SN2 nucleophilic substitution or elimination reaction in which the nucleophile is a solvent. Conventionally, solvolysis of chiral reactants through the SN1 yields a racemate (Chen et al., 2023). Sometimes, the stereochemistry pathway is complex given that the leaving anion remains close to the carbocation, thus shielding it from an attack ... Read More

Experiment #11 Chemical Equilibrium: Determination of an Equilibrium Constant

1.0 Abstract This lab was purposed to find the equilibrium constant in the reaction involving the formation of iron (III) thiocyanate. The lab was based on scientific concepts of Beer’s and the Chartelier’s principles. The constant equilibrium value of 167.10 was reliable as the percentage error was only 25.64 %, indicating high accuracy and reliability ... Read More

Investigating the Effect of Potential Hydrogen (pH) on Enzyme Activity

Abstract This experiment investigated how pH affects catalase activity, essential for understanding how enzymes function in biological systems. The experiment used catalase enzyme solution, hydrogen peroxide solution, and pH-varying buffer solutions in six test tubes. The test tubes were labeled with buffer solution pH values, and the reaction was allowed to occur in a 37°C ... Read More

Investigating How an Increase in Temperature Affects the Concentration of Aspirin

Research question What are the impacts of an increase in temperature on aspirin concentration? Introduction and Rationale The objective of the investigation is to evaluate how increased temperatures affect aspirin concentration. Temperature is one of the key factors that alter the reaction rate in most chemical reactions and can be used to evaluate the strength ... Read More

Organic Chemistry: Hybridization

Part A Hybridisation According to the valence bond theory, hybridization is mixing atomic orbitals to produce new hybridized orbitals better suited for pairing electrons to form chemical bonds because they have different energies and shapes than the original atomic orbitals. To link to four different atoms, for instance, the valence-shell s orbital combines with three ... Read More

Effect of Different Sugars on the Rate of Respiration of Yeast

Research Question Do different sugars affect yeast’s respiration rate compared to two monosaccharides and two disaccharides during aerobic respiration? Introduction and Rationale One of the central aspects of aerobic respiration is that it takes place in the presence of oxygen and is used in various life aspects, such as fermentation. I first learned about fermentation ... Read More

The Genetic Control and Chemical Interaction of Caffeine

Introduction Caffeine is one of the most widely utilized behaviorally active substances globally. Caffeine is a psychoactive drug that influences various neurotransmitter systems, such as activating noradrenaline neurons and antagonizes adenosine receptors. Adenosine downregulates the central nervous system. Therefore, inhibiting its function, caffeine leads to the activation of the brain’s medullary, vagal, vasomotor, and respiratory ... Read More

Essays On Chemistry

Discussing chemistry within an essay format is a great topic because of chemistry’s relevance in everyday life. Chemistry helps by exploring things that are unknown, examining the future behavior of plants, animals, chemicals, and compounds to better use these things directly or indirectly in our daily lives.

Writing essays on chemistry is a delicate balance, but doesn’t have to be a dry and boring experience. Chemistry is all around us, from the product labels we deal with daily, to the pastries and meals we enjoy. Cooking and baking are just another form of chemistry experimentation. Folding this knowledge of chemistry’s breadth into an essay on chemistry can help show your understanding of the topic and engage with your reader.

How to write an essay on Chemistry

An essay on chemistry is essentially a guided journey through a chemistry experiment. In turn, it should address all the stages of the scientific method to communicate a discovery or process.

An essay on chemistry should:

• Formulate a question.
• Conduct background research.
• Construct a hypothesis.
• Experiment and analyze data.
• Form a conclusion.

An essay on chemistry is usually separated into four main parts. These parts create a “chemical story” that the reader can follow along with, creating resonance and understanding.

These four parts are:

• Introduction – The first three steps of the scientific method. Include a question, rigorously cited examples of previous research, and a hypothesis or topic sentence.
• Results and Discussion – What work have you done, and what were the results? This is usually the longest section.
• Conclusion – Summarize the main purpose of the report.
• Experimental – Often separate from the narrative of the rest of the paper, this is where the raw data and in-depth experimental information are included.

What can you talk about in an essay on Chemistry?

Chemistry is a hugely varied topic with many different cases of study. So the most important thing with your topic is to demonstrate a thorough understanding and grasp of the subject.

Topics can include:

• Electrochemistry
• The discovery of Oxygen
• Water purification
• The discovery of Hydrogen
• Thermochemistry
• The discovery of Nobel gases
• Stiochiochemistry

And if you are stuck and don’t know what to add to your paper, essay samples on this page may help you to solve this issue and complete your assignment receiving the desired result!
