In the reaction Ca 2 H2O -> Ca(OH)2 H2, if starting with 1.05 moles of Ca and 2.05 moles of water, which is the limiting reactant

Water is the limiting reactant.

Explanation:

Hello.

In this case, for the reaction:

Having the moles of both calcium and water, we compute the moles of hydrogen yielded by each reactant, considering the 1:1 and 2:1 mole ratios regarding calcium to hydrogen and water to hydrogen:

Thus, since the water yields fewer moles of hydrogen we infer water is the limiting reactant whereas calcium is the excess one.

Best regards.
