Introduction: Chemical equations show how compounds and elements react with one another. An element is a substance consisting of one kind of atom, such as aluminum (Al) or oxygen gas (O2). A compound is a substance made of more than one kind of atom, such as water (H2O) or table salt (NaCl).

Practice:Balance each of the chemical equations below. (Some equations may already be in balance.) And then below it, classify the reaction as a synthesis, decomposition, single replacement, or double replacement reaction.
Match: Most chemical reactions can be classified as one of four types. Using your notes as a guide, match the following definitions to the type of reaction. Drag the term to match to the correct definition.
Double replacement
One reactant is broken down into two or more products.
Single replacement
Two or more reactants combine to form one product.
Synthesis
Two compounds react to form two different compounds.
Decomposition
A compound reacts with an element to form a new compound and a different element.
