CaCO3 + 2HCl 一> CaCl2 + H2O + CO2 From the equation above, what mass of CaCO3 will be required to produce 11.1g of CaCl2? [Ca=40, C=12, O=16, Cl=35.5]

A. 10 g

B. 1000 g

C. 14.6 g

D. 33.33 g

Calculation

CaCO3 + 2HCl 一> CaCl2 + H2O + CO2

   m                              11.1

[40+12+48]             [40+70]                              

m=(11.1*100)/110

m= 10 g

The correct answer is A. 10g

PQN: 8
