Back

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

Front

What is a decomposition reaction?

Back

A type of chemical reaction where a single compound breaks down into two or more simpler products.

What is a single replacement reaction?

Back

A type of chemical reaction where one element replaces another element in a compound.

Front

What is a double replacement reaction?

Back

A type of chemical reaction where the anions and cations of two different compounds exchange places, forming two new compounds.

How do you balance a chemical equation?

Back

By ensuring that the number of atoms of each element is the same on both sides of the equation, often by adjusting coefficients.
