The total mass of the products will always be equal to the total mass of reactants. This is because no atoms are ever destroyed or created during a reaction.
2 of 5
Limiting reactant
A limiting reactant is the reactant that gets completely used up in a given reaction.
3 of 5
Reactant in excess
There is more than enough present for the limiting reactant to be fully used up.
4 of 5
