Answer
'Excess reactant'
Explanation
## Step 1:In a chemical reaction, the reactant that determines when the reaction stops is known as the limiting reactant. This reactant is completely consumed during the reaction.## Step 2:Any reactant that is present in quantities greater than necessary to react with the limiting reactant is known as the excess reactant. This reactant is not completely used up during the reaction.## Step 3:After the chemical reaction is complete, the substance that remains unreacted is the excess reactant.
