A sample of 0.47 g of carbon dioxide was obtained by heating 1.19 g of calcium carbonate. What is the percent yield for this reaction?

CaCO₃(s) → CaO(s) + CO₂(s)

Determine the limiting reactant when 0.45 g of Cr and 0.69 g of H₃PO₄ react according to the following chemical equation. (Omit states-of-matter from your answer.)

2 Cr + 2 H₃PO₄ → 2 CrPO₄ + 3 H₂
