Answer 1

When balancing a chemical equation, a **coefficient** can be placed to the left of a formula of a substance to help balance the equation. Coefficients indicate the number of moles or molecules of that substance involved in the reaction. By adjusting these coefficients, you can ensure that the number of atoms for each element is the same on both the reactant and product sides of the equation.
