Complete and balance the following reactions, state whether dilute or conc. acid is used.
(a) NH4OH+HCl→
(b) NaHSO3+HCl→
(c) Pb(NO3)2+HCl→
(d) Pb3O4+HCl→
(e) Zn+HCl→
(f) Ca(HCO3)2+HCl→
The balanced chemical equations for the reactions are following:
(a) HCl(aq)+NH4OH(aq)⟶H2O(l)+NH4Cl(aq)
(b) HCl(aq)+NaHCO3(s)→NaCl(aq)+H2O(l)+CO2(g)HCl(aq) + NaHCO_3(s) \rightarrow NaCl(aq) + H_2O(l) + CO_2(g)HCl(aq)+NaHSO3(s)⟶NaCl(aq)+H2O(l)+SO2(g)
(c) Pb(NO3)2(aq)+2HCl(aq)⟶PbCl2(s)+2HNO3(aq) Pb(NO3)2(aq)+ 2 HCl(aq)→PbCl2(s)+ 2HNO3(aq)Pb(NO_3)_2(aq) + 2 HCl(aq) \rightarrow PbCl_2(s) + 2HNO_3(aq)
(d) 2PbO3+16HCl⟶6PbCl+8H2O+5Cl2
(e) Zn+2HCl⟶ZnCl2+H2
(f) Ca(HCO3)2+HCl⟶CaCl2+CO2+H2O Ca(HCO3)2 + 2 HCl→ CaCl2 + 2 CO2 + 2 H2OCa(HCO_3)_2 + 2 HCl \rightarrow CaCl_2 + 2 CO_2 + 2 H_2O
