Lithium oxide is used aboard the space shuttle to remove water from the air supply according to the equation li2o(s)+h2o(g)→2lioh(s) if 80.0 kg of water is to be removed and 65 kg of li2o is available, which reactant is limiting?

is a limiting reactant.

Explanation:

As can be seen from the balanced equation 1 mole of is required to remove 1 mole of   .

Thus 2175.36 moles of will only be able to remove 2175.36 moles of . Thus limit the formation of products and is called as limiting reagent.

(4441.97-2175.36) = 2266.61 moles of water are present in excess and thus water is here present as an excess reagent.
