Front

How do you balance a chemical equation?

Back

Adjust the coefficients of the reactants and products to ensure the same number of each type of atom on both sides.

Front

What is the law of conservation of mass?

Back

In a chemical reaction, mass is neither created nor destroyed; the total mass of reactants equals the total mass of products.

Front

What are coefficients in a chemical equation?

Back

Numbers placed before compounds in a chemical equation to indicate the number of molecules or moles.
