Read each question carefully and answer to the best of your ability.
1. What is the definition of a limiting reagent?
The reagent that is completely consumed in a reaction.
The reagent that is left over after a reaction.
The reagent that is in excess.
The reagent that speeds up a reaction.
2. In the reaction 2H₂ + O₂ → 2H₂O, if you have 4 moles of H₂ and 1 mole of O₂, which is the limiting reagent?
H₂
O₂
