Answer 1

1) Na2Co3+ 2HCl= 2NaCl+H2Co3

Total Ionic reaction =

2na^+ + co3^-2. = 2H^+ + 2Cl^- = 2Na^+ + 2Cl^- + 2H^+. + co3^-2

Ionic reaction=2H+ + Co3-2= H2CO3

2)Na2Co3+ cu(no3)2= 2Nano3+CuCo3

Total Ionic reaction =2na^+ + co3^-2. +Cu^+ + 2No3^- = 2Na^+ + 2Cl^- + Cu+. + 2No3^-

Ionic reaction=Cu^+ + Co3-2= H2CO3

3) Al+ CuCl2= alcl3+ cu

4) Al+ mag(no3)2= alno3+ mg

3) no reaction

4) ZnCo3+ 2HCl= 2ZnCl+H2Co3

Total Ionic reaction =Zn^+2 + co3^-2. = 2H^+ + 2Cl^- = 2Na^+ + 2Cl^- + 2H^+. + co3^-2

Ionic reaction=2H+ + Co3-2= H2CO3
