Question

10.

Given the following reaction
Ca(s) + 2HCl(aq) → CaCl2(aq) + H2(g)
If 1.00 g of Ca reacts with 1.00 g HCI and 1.21 g CaCl2 are produced, what is the theoretical yield, the percent
yield and the limiting reactant?
a. 2.77 g, 43.7%, Ca limiting
b. 2.77 g, 79.5%, HCI limiting
c. 1.52 g, 43.7%, Ca limiting
d. 1.52 g, 79.5% HCI limiting
e. 2.77g, 54.9%, Ca limiting
f. 1.52 g, 54.9%, HCI limiting

Answer 1

The given reaction is calcium, solid, plus 2 h c, l gives c a c l, 2 plus hydrogen. Here we can write 1 mole of calcium, reacting with 2 moles of h, c l ...
