What are the larger numbers that you CAN CHANGE In a chemical equation? Subscripts Reactonts Coefficient Products

## Step 1In a chemical equation, the substances involved are represented by their chemical formulas. The numbers in these formulas are called subscripts. For example, in the formula , the subscript 2 indicates that there are two hydrogen atoms in each molecule of water.## Step 2Reactants are the substances that undergo a chemical reaction. They are written on the left side of the chemical equation. For example, in the equation , and are the reactants.## Step 3Coefficients are numbers placed before the formulas of the reactants and products in a chemical equation. They indicate the number of molecules or atoms of the substance involved in the reaction. For example, in the equation , the coefficients are 2 for , 1 for , and 2 for .## Step 4Products are the substances formed as a result of a chemical reaction. They are written on the right side of the chemical equation. For example, in the equation , is the product.## Step 5Among the options provided, only the coefficients can be changed in a chemical equation to balance it. Changing subscripts would change the identity of the substance, and the terms "reactants" and "products" refer to the substances themselves, not the numbers that can be changed.
