Final answer:

Explanation of limiting reagent concept in chemical reactions.


Explanation:

Before the reaction:

  1. 2 moles of hydrogen react with 1 mole of oxygen to produce 2 moles of water.
  2. Theoretical calculations indicate how much of each reactant is needed for the reaction.
  3. The reactant that runs out first is the limiting reagent.

After the reaction:

  • The reactant that is entirely consumed is the limiting reagent.
  • The excess reactant remains unreacted after the reaction is complete.
