Answer 1

Cu(OH)2+2HCl=CuCl2+2H2O
Cu(OH)2+2H+2Cl=Cu+2Cl+H2O
Cu(OH)2+2H=Cu+H2O

K2CO3+2HNO3=2KNO3+H2O+CO2
2K+CO3+2H+2NO3=2K+2NO3+H2O+CO2
CO3+2H=H2O+CO2

3NaOH+H3PO4=Na3PO4+3H2O
3Na+3OH+3H+PO4=3Na+PO4+3H2O
3OH+3H=3H2O

2KNO3+Na2SO4=K2SO4+2NaNO3
2K+2NO3+2Na+SO4=2K+SO4+2Na+2NO3

MgCO3+2HCl=MgCl2+H2O+CO2
MgCO3+2H+2Cl=Mg+2Cl+H2O+CO2
MgCO3+2H=Mg+2H2O+CO2

Fe(NO3)3+3KOH=3KNO3+Fe(OH)3
Fe+3NO3+3K+3OH=3K+3NO3+Fe(OH)3
Fe+3OH=Fe(OH)3
