A gas generation tube contains both the reactants involved in a chemical reaction and the gases that are produced.
Lady bird [3.3K]

The reaction will come to an end if all the reactants are used up. The reaction's limiting reactant is reactant B.

Limiting Reactant: The limiting reactant is the one that is consumed first and sets a limit on the quantity of product(s) that can be obtained.

This reactant is the one that restricts the production of products throughout the reaction. The reaction will come to an end if all of the reactants are used up.

surplus reactant
