30.0 mL of 0.500 M hydrochloric acid is mixed with 2.50 g of calcium carbonate (CaCO₃). The reaction is: CaCO₃ + 2 HCl → CaCl₂ + CO₂ + H₂O. Identify the limiting reagent and calculate (i) the volume of CO₂ produced at STP and (ii) the mass of CaCl₂ formed. Give the volume in litres (three significant figures) and the mass in grams (three significant figures).

Answer Options

A. CaCO₃ is limiting; CO₂ = 0.250 L; CaCl₂ = 1.25 g
B. HCl is limiting; CO₂ = 0.150 L; CaCl₂ = 0.750 g
C. HCl is limiting; CO₂ = 0.200 L; CaCl₂ = 1.00 g
Correct Answer D. HCl is limiting; CO₂ = 0.168 L; CaCl₂ = 0.832 g
Correct Answer
D
Correct Option:
HCl is limiting; CO₂ = 0.168 L; CaCl₂ = 0.832 g
