Founded on 17 August 2012, ChemistrySAANguyen is dedicated to improve your understanding, retentions of chemistry concepts and to allow you to develop your own set of resource to help review. A one-stop portal for all things chemistry, ChemistrySAANguyen is the authoritative source for the major points about the chapters, including high quality pictures, videos, examples, and game activities.  A solution is a homogeneous mixture, a mixture in which the components are uniformly intermingled. This means that a sample from one part is the same as a sample from any other part. The substance present in the largest amount is called the solvent, and the other substance or substances are called solutes. For example, when we dissolve a teaspoon of sugar in a glas* of water, the sugar is the solute and the water is the solvent. Aqueous solutions are solutions with water as the solvent. Because they are so important, in this chapter we will In this chapter we will look carefully at the properties of gases. First, we will see how measurements of gas properties lead to various types of laws—statements that show how the properties are related to each other. Then we will construct a model to explain why gases behave as they do. This model will show how the behavior of the individual particles of a gas leads to the observed properties of the gas itself (a collection of many, many particles). The study of gases provides an excellent example of the scientific method in action. It illustrates how observations lead to natural laws, which in turn can be accounted for by models. Reactions are what chemistry is really all about. Recall from Chapter 6 that chemical changes are actually rearrangements of atom groupings that can be described by chemical equations. These chemical equations tell us the identities (formulas) of the reactants and products and also show how much of each reactant and product participates in the reaction..
