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.

Chemistry Galvanic Cell

Purpose of Experiment: To determine the effect of concentration of reactants on the current produced by a galvanic cell. Hypothesis: The greater the concentration of solution in the two half cells reacting with the two metals to produce current, the greater the flow of current will be produced from the …

The Thickness of Aluminum Foil Lab

In the study of Chemistry, we encounter very large and very small numbers. For example, the size of a molecule or thin layer of molecules is very, very small and difficult to measure directly. In order to “measure” such numbers, we often use one measured quantity and another known property …

Forensic Science Chemistry

Forensic chemistry is becoming an increasingly popular topic. It is being used quite often in the real world with police investigations, cases, and is also being magnified in television shows including Forensic Files, CSI, and Bones (What is Forensic Chemistry?). Forensic chemistry is important because without it we wouldn’t know …

Laboratory Techniques and Measurements Argumentative

A. Water boils at 100°C at sea level. If the water in this experiment did not boil at 100°C, what could be the reason? The reason why water did not boil at 100°C could be because we are not at sea level; the pressure could be lower. B. While heating …

Cell Transport Mechanisms and Permeability Persuasive

1. What is the molecular weight of Na+? The molecular weight of Na+ is 23. 2. What is the molecular weight of Cl-? The molecular weight of Cl- is 35. 3. Which MWCO dialysis membranes allowed both of these ions through? The MWCOs that allowed both of these ions through …

Radical Halogenation and Gas Chromatography

In radical halogenations lab 1-chlorobutane and 5% sodium hypochlorite solution was mixed in a vial and put through tests to give a product that can then be analyzed using gas chromatography. This experiment was performed to show how a radical hydrogenation reaction works with alkanes. Four isomers were attained and …

Seperating the Components of Panacetin

Part A 2.014 g of Panacetin was measured and put inside a 125 mL Erlenmeyer flask. 35 mL of Dichloromethane (DCM) was added to the 125 mL Erlenmeyer flask. After addition of DCM the Panacetin lumps were crushed with a stirring rod. Next a fluted filter paper was pre-weighed. The …

Standardizing a Solution of Potassium Hydroxide

Abstract: In this lab, a prepared solution of Potassium Hydroxide will be standardized. The solution we will be standardized by performing multiple calculations to ensure the upmost accuracy. The acid used for this titration will be KHP (C4H5KO4). Phenolphthalein we be added to the beaker of the dissolved acid before …

Chemistry in Photography

A photograph is an image made by a photo-chemical reaction which records the impression of light on a surface coated with silver atoms. The reaction is possible due to the light-sensitive properties of silver halide crystals. Equation form for silver halides: Ag + + e – Ag Species produced include: …

Colorimetric Analysis: Manganese in Steel

The goal of the experiment is to determine the percentage of Mn in an unknown metal sample by means of colorimetric analysis. First stock solution of KMnO4 with known concentration was diluted and then carried to spectrometer for analysis. The peak with highest absorbance was taken as λmax. Then the …
