7.Kl(s) + H2SO4(l)=
8. NaOCl(aq) + Kl(aq) + H2O(l)=

2. Write net ionic equations for each of the above reactions
except 6 and 7

Answer 1

1)

NH₄Cl(s) + NaOH(aq) = NH₄OH + NaCl(aq)

total ionic equation

NH₄⁺ (aq) + Cl^- (aq) + Na⁺ (aq) +OH^- (aq) ------> H2O(l) + NH3(g) + Na⁺ (aq) + Cl^- (aq)

Net ionic equation

NH₄⁺ (aq) + OH^- (aq) ------> H2O(l) + NH3(g)

2)

H₂SO₄(aq) + Na₂CO₃(s) = Na₂SO₄(aq) + H₂O + CO₂(g)

total ionic equation

2Na⁺ + CO₃^2- + H⁺ + HSO₄^- --> 2Na⁺ + SO₄^2- + CO₂ + H₂O

net ionic equation

CO₃^2- + H⁺ + HSO₄^- --> SO₄^2- + CO₂ + H₂O

3)

CO₂(g) + Ca(OH)₂(aq) = CaCO₃(s) + H₂O(l)

Total ionic equation

Ca²⁺ (aq) + 2 OH^- (aq) + CO₂(g) → CaCO₃ (s) + H₂O (l)

Net ionic equation is same

4)

AgNO₃(aq) + HCl(aq) = AgCl(s) + HNO₃(aq)

Total ionic equation

Ag⁺ (aq) + NO₃^- (aq) + H⁺ (aq) + Cl^- (aq) = AgCl (s) + NO₃^- (aq) + H⁺ (aq)

net ionic equation is

Ag⁺ (aq) + Cl^- (aq) = AgCl (s)
