Explanation / Answer

3. H2SO4 (aq) + Na2CO3(aq) ---------> Na2So4(aq) + CO2(g) + H2O(l)

2 H+(aq)+SO42- (aq) + 2Na+(aq) +CO32-(aq) ---------> 2Na+(aq) +So42-(aq) + CO2(g) + H2O(l)

removal of spectator ions to get net ionic equation

2 H+(aq +CO32-(aq) ---------> CO2(g) + H2O(l)

Acid -Base reaction

4. HCl(aq) + NaOH (aq) -------------> NaCl (aq) + H2O(l)

    H+(aq) +C-l(aq) + Na+(aq)+OH- (aq) -------------> Na+(aq)+Cl- (aq) + H2O(l)

     removal of spectator ions to get net ionic equation

H+(aq) +OH- (aq) -------------> H2O(l)

Acid -Base reaction

5. HC2H3O2(aq) + NaOH (aq) --------> NaC2H3O2 (aq)+ H2O(l)

HC2H3O2(aq) +OH- (aq) --------> C2H3O2- (aq)+ H2O(l)

Removal of spectator ions to get net ionic equation

H+ (aq) +OH- (aq) --------> H2O(l)

Acid -Base reaction

6. NH4Cl(aq) + NaOH (aq)-------> NH4OH(aq) + NaCl (aq)

   NH4+(aq) +Cl-(aq) + Na+(aq) +OH-(aq) -------> NH4OH + Na+(aq)+Cl- (aq)

NH4+(aq) +OH-(aq) -------> NH4OH net ionic equation

salt hydrolysis

6.BaCl2(aq) + Na2So4(aq) ---------> BaSO4(s) + 2NaCl(aq)

Ba+2(aq)+2Cl-(aq) + 2Na+(aq) +So42-(aq) ---------> BaSO4(s) + 2Na+(aq)+2Cl-(aq)

Ba+2(aq)+So42-(aq) ---------> BaSO4(s) net ionic equation
