What is a Combustion Reaction?

Back

A reaction that occurs when a substance combines with oxygen, releasing energy in the form of light or heat.

Front

What is a Synthesis Reaction?

Back

A reaction where two or more reactants combine to form a single product.

Front

What is a Single Replacement Reaction?

Back

A reaction where one element replaces another element in a compound.

Front
