Expert Answer
1)Lab.preparation of ammonia using an ammonium salt :
2NH4Cl + Ca(OH)2 → CaCl2 + 2H2O + 2NH3
2)The reaction of ammonia with the excess of chlorine
NH3 + Cl2 → NCl3 + HCl
3) The reaction of ammonia with sulphuric acid
2NH3 + H2SO4 → (NH4)2SO4
4) From the list of gases -ammonia, ethane, hydrogen chloride, hydrogen sulphide, select the gas which is used to reduce copper oxide to copper
Ammonia gas is used to reduce copper oxide to copper
2NH3 + 3CuO → 3Cu + 3H2O + N2↑
