Abstract
This paper is a write-up of two experiments in chemistry. The first is a write-up of an experiment in calorimetry, looking at the heat of fusion of ice. The second is an experiment on the specific heat of metals, looking at the specific heats of copper and tin. The experimental details are described.
From the Paper
"The first experiment looks at the heat of fusion of ice -- the amount of heat needed to convert a solid into a liquid at constant temperature and pressure is the heat of fusion of the substance. The molar heat of fusion is the amount of heat energy required to completely change one mole of solid into one mole of liquid at its melting point. In this experiment the molar heat of fusion of...."

Abstract
This is a writeup of chemistry experiments in synthesis, decomposition, single displacement and double displacement reactions with explanations of materials, methods and results. Discusses the procedures of the experiment.
From the Paper
"Each chemical equation represents a specific chemical reaction and identifies the reactants and products. Reactants appear on the left side of the equation and products on the right side separated by an arrow indicating the direction in which the reaction takes place. Equations must be balanced to be correct meaning the same number of each kind of atom must appear on each side of the equation. For example, when iron rusts it combines with oxygen to form a new compound iron oxide Fe O and..."

Abstract
This paper looks at hydrates, and how to calculate their water content. It calculates the water content for copper sulfate hydrate and magnesium chloride hydrate.
From the Paper
" A hydrate is a type of salt containing water within its crystal structure. In this experiment the mass percent of water in a hydrate was determined by heating a sample of the hydrate to remove the water and then comparing the mass of the sample before and after heating. From this the empirical formula of the hydrated salt was determined. This was carried out for copper sulfate hydrate CuSO XH O and for magnesium chloride hydrate MgCl XH O. A crucible was weighed to the..."

Abstract
This paper looks at the techniques used by a forensic toxicologists, particularly when looking for drugs in the body postmortem. It looks at what factors have to be considered which change drug levels after death. The paper also looks at how blood alcohol levels are tested when drunk driving is suspected.
From the Paper
"Forensic toxicology is a specialty area of analytical chemistry. Forensic Toxicology is the science of the adverse effects of chemicals on living organisms and a toxicologist detects and identifies foreign chemicals in the body in particular toxic or hazardous substances. Forensic toxicologist usually receive samples for analysis as preserved samples of body fluids stomach contents and body parts. They have access to coroner's reports which will give them any signs and symptoms and postmortem data that may be helpful. Because most substances entering the body are changed..."

Density, 2004.
A look at how density can be used to identify an object.
3,375 words (approx. 13.5 pages), 8 sources, APA, $ 119.95
»
Click here to show/hide summary
Abstract
This paper covers the following six topics: 1. identity determined from density. 2. changes of speed and motion of molecules with state change. 3. theory of structure of atom. 4. periodic table vs alphabetical listing of elements. 5. mass nos, moles. 6. Henry's law.
From the Paper
"Density can be used to identify a substance. It could be used to determine if a sample of gold-colored metal is in fact gold. Archimedes used the concept of density to identify substances. Density is a physical property of a substance which describes the degree of compactness of the substance, i.e., how close together the atoms are packed. The density of a substance is the ratio of an object's mass to its volume."
