Define a physical change.
Alters the form of a substance but not its chemical identity.
Define a chemical change.
Results in the formation of new substances with different chemical properties.
What are reactants?
Substances that react (left side of the equation).
What are products?
Substances formed in a chemical reaction (right side of the equation).
Define a synthesis reaction.
Two or more reactants combine to form a single product.
Define a decomposition reaction.
A single reactant breaks down into two or more products.
What is a combustion reaction?
A reaction involving organic molecules reacting with oxygen to produce CO2 and H2O.
