Front

What is the law of conservation of mass?

Back

Matter cannot be created or destroyed in a chemical reaction; it can only change forms.

Front

What type of reaction occurs when two or more substances combine to form a single product?

Back

Front

What is a decomposition reaction?

Back

A chemical reaction where a single reactant breaks down into two or more products.

What is a single replacement reaction?

Back

A reaction where one element replaces another in a compound.
