Question

11. Balance the following equations :
(a) ZnCO2 (s) + HCl (aq) ZnCl2 (aq) + H2O (1) + CO2 (g)
(b) NH4Cl (s) + Ca(OH)2 (s) → CaCl, (s) + NH3 (g) + H2O (1)
(c) Cu (s) + H2SO4 (aq) CuSO4 (aq) + SO2 (g) + H2O (1)​

Answer 1

"

Answer:

ZnCO3 (s) + 2 HCl (aq) -->ZnCl2 (aq) +H2O (1) +CO2 (g)

2 NH4Cl (s) + Ca(OH)2 (s) → CaCl2 (s)+ 2NH3(g)+2H2O

Cu (s)+ 2 H2SO4 (aq)-->CuSO4 (aq) +SO2 (g)+2 H2O(1)
