## Step 1<br />In a chemical reaction, the reactants are the substances that undergo a chemical change to form the products. The reactants are the starting materials in a chemical reaction.<br /><br />## Step 2<br />The excess reagent is the reactant that is present in a larger amount than is required to react with the other reactants. This means that it is not completely consumed in the reaction.<br /><br />## Step 3<br />The excess reagent does not control the reaction. The reaction is controlled by the limiting reagent, which is the reactant that is completely consumed in the reaction.<br /><br />## Step 4<br />The excess reagent is not completely consumed in the reaction. This is because it is present in a larger amount than is required to react with the other reactants.<br /><br />## Step 5<br />The excess reagent is present in a larger amount than the limiting reagent. This is because it is not completely consumed in the reaction, while the limiting reagent is completely consumed.
