Back

Coefficients are the numbers placed in front of the compounds in a chemical equation to indicate the number of molecules or moles of each substance.

Front

What is a reactant?

Back

A reactant is a substance that undergoes a chemical change in a reaction.

What is the significance of balancing chemical equations?

Back

Balancing chemical equations is important because it ensures that the Law of Conservation of Mass is obeyed, meaning the same number of atoms of each element is present on both sides of the equation.
