  The fact that chemical reactions can neither create nor destroy atoms is called the law of conservation of atoms or the law of conservation of matter. In this usage, conservation means that what you start with is conserved at the end. Lesson 9.1 Chemical Reactions and equations Dahm-c09_165-196hr.indd 166 5/28/12 5:32 PM

  Reactions - Lesson 2: Balanced Chemical Equations 13 Another way to consider the Law of Conservation of Mass is that atoms that start as reactants in a reaction are the same atoms that are in the resultant products. Reactions generally involve the rearrangement of the original atoms of the reactants into a new arrangement, which produces the ...

  4 Types of Chemical Reactions Notes Synthesis- two or more elements or compounds combine to form one compound. Decomposition-a single compound decomposes into two or more elements or smaller compounds. Single Replacement- a metal will replace a less active metal in an ionic compound OR a nonmetal will replace a less active nonmetal. Double Replacement- the metals in ionic compounds switch places.

  Chemical bonds contain a form of energy called chemical energy. When a bond breaks, it absorbs energy from the surroundings. When a bond forms, it releases energy to the surroundings. Some chemical reactions release more energy than they absorb. Some chemical reactions absorb more energy than they release. You can feel this energy change as a
