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?
[Ar of C = 12; Zn = 65; O= 16; Cl = 35.5; H= 1]
(1)
☐ | A | 11.0 g | |
☐ | B | 13.8 g | |
☐ | C | 15.0 g | |
☐ | D | 22.0 g |
