WARM UP 1.List 6 things that a chemical equation tells you about a chemical reaction.

Chemical Equations Chemistry II

Chemical Equations 6 CO 2(g) + 6 H 2 O (l)  C 6 H 12 O 6(s) + 6 O 2(g) Reactants Products Yield # of atoms # of molecules state of matter

Law of Conservation of Mass Antoine Lavoisier Matter cannot be created or destroyed

Balancing Equations What goes in must come out – All elements have an equal number of atoms on each side of the equation Process – Change coefficients to increase numbers of atoms Balance and check one element at a time Example:

WRAP UP Write the balanced equation for the reaction between aluminum and oxygen gas that produces aluminum oxide.
