A Chemical Reaction represents a type of chemical change where reactants are transformed into products. 

Understanding Chemical Reactions

Concept #1: Observable Evidence of Chemical Reaction

Color changes, phase changes, and temperature changes are signs that a chemical reaction has occurred. 

Example #1: What happens on a molecular level when a chemical reaction occurs?

Concept #2: Symbols of Chemical Equations

Example #2: Write a chemical equation using correct formulas and symbols for the decomposition of solid sodium carbonate at high temperature to produce solid sodium oxide and carbon dioxide gas.
