A student wanted to make 15.0 g of zinc chloride. The equation for the reaction is:
ZnCO3 + 2HCl → ZnCl2 + CO2 + H2O
What mass of zinc carbonate should the student add to the hydrochloric acid to make 15.0 g of zinc chloride?
Relative atomic masses (Ar): C = 12 Zn = 65 O= 16 Cl = 35.5 H= 1
11.0 g
13.8 g
15.0 g
22.0 g
