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. By making order here, you get a 100% guarantee of quality and confidentiality.

Determination of the activation energy

Introduction: Chemical kinetics is the study of chemical reaction rates, how reaction rates are controlled and the pathway or mechanism by which a reaction proceeds from its reactants to its products. Reaction rates vary from the very fast, which is may complete in microseconds or even nanoseconds, to very slow, …

The Great Metabolic Race

Organisms are constantly undergoing various chemical reactions and pathways that enable for them to maintain life. These pathways are part of metabolism, involving catabolism (break down of organic nutrients for extraction of useful) and anabolism (energy dependent conversion of small precursor molecules in complex molecules); some of which are energy …

Bone Tissue

1. Describe bone tissue and the role each component plays in bone physiology and remodeling. What is the difference between compact and spongy bone? (2 points) Spongy bone looks like a sponge hence the name and contains a lot of red bone marrow (medulla ossium rubra). Red bone marrow is …

Ocean County College

The purpose of this experiment was to construct a Beer’s Law Plot, determine the concentration of a sample using the Beer’s law plot, and to determine the concentration of Blue Dye #1 in a commercial product using visual Colorimetry. Procedure This lab consisted of calculating %T of given data and …

Separating The Components Of Panacetin

Abstract In this lab we separated components of a simulated preparation, panacetin and making use of its acid base properties. To obtain such a pure compound, the compound we want must be separated from its other natural components, which can be done by manipulating physical and chemical properties. Panacetin contains …

Determination of Ka of Weak Acids

Purpose: The purpose of this lab is to find the strength of weak acids by determining the equilibrium constants for their ionization reactions in water. Is to use their measured pH values to calculate the pKa for the two unknown weak acids thus determining their identities. Hypothesis: If we neutralize …

Biosynthesis of Ethanol from Sucrose

Introduction: Ethanol can be created using two methods: acid catalysed hydration of ethylene and through fermentation of sucrose. The purpose of this experiment was to use fermentation to produce ethanol from commercial sucrose (store-bought sugar), using fractional distillation of the fermented solution. The percent ethanol in the fermented solution was …

Acid Base PH Lab

Background Information: The pH is the measurement of how acidic or how basic a substance can be. The pH scale is used to measure how acidic or basic a living cell can be. The pH scale ranges from 0-14; 0-6 being acidic, 8-14 being basic and 7 being neutral. There …

Acids and Bases Worksheet

Before You Begin: You may either copy and paste this document into a word processing program of your choice or print this page. Directions: Answer the following questions in complete sentences. 1. Describe four properties of acids that you learned in this lesson. React with bases, react with metals, make …

Physical properties of organic compound

Boiling point is the exact temperature that the state of compound change from liquid to gas, which need to break the intermolecular forces. The stronger the intermolecular forces, the higher the boiling point. Since straight chain alkane, alkene and alkyne only experience dispersion forces, the compound with more carbons have …
