Chemistry Essays

Chemistry essays are different from those who are more related to creative writing. They should be based on critical thinking, logic, and proper evaluation. Sometimes these essays are built on solving chemical equations and other problems. You need to have the solid theoretical background to prepare homework which deserves the highest grade. When students cannot cope with the tasks alone, they seek help at writing service. Our company is one of the best in this specialization. We do not only offer free samples on any topic but help with preparing the entire work within the quickest time.

You can find these chemistry samples only at this category of our website. We share the best papers prepared by our qualified experts to attract more customers. If you like the way our texts are written, you can always drop us a line in the online chat, and we will begin solving your assignment.

Factors affect the rate of the decomposition of hydrogen peroxide

Aim: Our aim is to detect which factors affect the rate of the decomposition of hydrogen peroxide with a fixed mass of catalyst. A catalyst is a substance, which alters the speed, or rate of a chemical reaction but is chemically unchanged at the end of the reaction. The two …

Depletion of the Ozone Layer: Its causes, effects, and possible solutions

The depletion of the ozone layer is a major concern today. The ozone layer protects us from the harmful rays of the sun; therefore it is imperative that we preserve it. Since more pollutants are produced today than ever before (because of the major increase in the population), there is …

Asahi Glass Company: Strategy

1. Asahi Glass Company has diversified through internal growth, acquisition, and joint ventures from its origin in flat glass to broad glass-materials, chemical, and electronics manufacturer. It has also vertically integrated and expanded internally to become the leading global glass manufacturer. In 1993, Asahi Glass is reviewing its future direction, …

The Aldol Condensation: Synthesis of Dibenzalacetone

Objective: The benefit of this lab was to acquaint oneself with the fundamentals of the Aldol Condensation reaction by demonstrating the synthesis of dibenzalacetone (trans, trans-1,5-Diphenyl-1,4-pentadien-3-one) through the aldol condensation of acetone with benzaldehyde. The synthesis began by using a strong base to generate the acetone enolate ion. The ketone/enol …

Reaction (rate) between magnesium ribbon and hydrochloric acid

Introduction In the experiment the magnesium reacts with the hydrochloric acid to create magnesium chloride and hydrogen. The balanced formula for this is: Mg(s) + 2HCL(aq) MgCl2(aq) + H2(g) Magnesium + hydrochloric acid Magnesium Chloride + Hydrogen Magnesium will react with hydrochloric acid, because it is higher in the reactivity …

Drug: Lithium

Lithium is the first choice of treatment for bipolar disorders and it is indicated that Lithium is effective in the alleviation of manic and depressive episodes. 75-80% of patients who take Lithium as directed show improvement. One patient, on page 177 of the textbook, states that Lithium prevents his “disastrous …

A lab of Reduction/Oxidation Reactions

Research Question: Is it possible to determine if a redox reaction took place by using only the equation? Hypothesis: Yes, I believe it is possible to determine if this reaction took place by using the oxidation numbers in the equation. Variables: 1. I cleaned the reaction surface to limit contamination …

Finding the concentration of a Potato cell

Aim The aim is to find the concentration (mole/dm3 (M)) of solute in a potato cell by using the process of osmosis and different concentrations of sucrose solution. Background information Osmosis is diffusion of water across a partially permeable membrane. It moves from a solution with less solute concentration (high …

Percent Yield of a Precipitate

Purpose The purpose of the experiment is to determine the percent yield of the precipitate; by performing double displacement reaction between solutions of two different compounds. Introduction First of all when making a solution of two different compounds; there will many variables that can be considered during the experiment. However, …

Natural and Common pH indicators experiment

An indicator is a halochromic chemical compound that is added to a solution to determine its pH. It is a chemical detector for hydronium ions. The indicator changes colour to show the pH of the solution. Some indicates are not very precise and only tell us whether the solution is …
