Question 33

Hydrochloric acid containing 0.60 mol of HCl reacts completely with calcium carbonate. The equation for the reaction is CaCO3+2HCl→CaCl2+H2O+CO2\mathrm{CaCO_{3}} + 2\mathrm{HCl} \rightarrow \mathrm{CaCl_{2}} + \mathrm{H_{2}O} + \mathrm{CO_{2}}CaCO3​+2HCl→CaCl2​+H2​O+CO2​. What amount of calcium carbonate is used up?

[1]
A

0.20 mol

B

0.30 mol

C

0.60 mol

D

1.2 mol
