Chemistry Summary The particle theory: 1. Matter is made of tiny particles 2. Particles of matter are in constant motion 3. Particles of matter are held together by very strong electric forces 4. There are empty spaces between the particles of matter that are very large compared to the particles themselves. 5. Each substance has unique particles that are different from the particles of other substances 6. Temperature affects the speed of the particles. The

A Chemical change is any change that results in the formation of a new chemical substance. It is something that everyone learns about in school‚ but never really tries to see it in the real world. We all know the basic examples; baking a cake‚ burning wood… etc. What about the examples that are happening around us. For example‚ the Statue of Liberty has been through a chemical change. It was first a dull brown color‚ and now it is a green color. That happened due to a chemical change. During the

CHEM 1105 Experiment 4: Determination of a Chemical Formula Introduction When atoms of one element combine with those of another‚ the combining ratio is typically an integer or a simple fraction. The simplest formula of a compound expresses that atom ratio. When two or more elements are present in a compound‚ the formula still indicates the atom ratio. To find the formula of a compound we need to find the mass of each of the elements in a weighed sample of that compound. For example‚
