A solution of ammonium chloride plus sodium hydroxide

A solution of lead(II) nitrate plus a solution of sodium sulfate

A solution of bromic acid plus a solution of sodium nitrate

A solution of calcium nitrate plus a solution of potassium chloride

Answer 1

a) Ca(s) + 2 HCl(aq) -----> CaCl₂(aq) + H₂(g)

Total ionic equation : Ca(s) + 2 H+(aq) + 2Cl-(aq)-----> Ca2+ (aq) + 2Cl-(aq) + H₂(g)

Net ionic equation : Ca(s) + 2 H+(aq) ------>  Ca2+ (aq) + H₂(g)

b) Cl2(g) + 2KBr(aq) -----> 2KCl(aq) + Br2(l)

Total ionic equation : Cl2(g) + 2K+ (aq) + 2Br-(aq) -----> 2K+ (aq) + 2Cl-(aq) + Br2(l)

Net ionic equation: Cl2(g) + 2Br-(aq) ---------> 2Cl-(aq) + Br2(l)

c) NH4Cl(aq) + NaOH(aq) -----> NH3(g) + NaCl(aq) + H2O(l)

Total ionic equation :

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

Net ionic equation:

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

d) Pb(NO3)2 (aq) + Na2SO4 (aq) -----> PbSO4 (s) + 2NaNO3 (aq)

Total ionic equation :

Pb2+ (aq) + 2NO3- (aq) + 2Na+ (aq) + SO₄2- (aq) -----> PbSO4 (s) + 2Na+ (aq) + 2NO3- (aq)

Net ionic equation :

Pb2+ (aq) + SO₄2- (aq) -----> PbSO4 (s)

e) HBr(aq) + NaNO₃(aq) -----> HNO₃(aq) + NaBr(s)

Total ionic equation :

   H+(aq) + Br-(aq) + Na+ (aq) + NO₃-(aq) ------> H+(q) + NO3-(aq) + NaBr(s)

Net ionic equation:

Br-(aq) + Na+ (aq) ------> NaBr(s)

f) Ca(NO3)2 (aq) + 2 KCl (aq) → CaCl2(s) + 2 KNO3 (aq)

Total ionic equation :

   Ca2+ (aq) + 2NO3- (aq) + 2K+ (aq) + 2Cl-(aq) ----------> CaCl2(s) + 2K+ (aq) + 2NO3- (aq)

Net ionic equation:

   Ca2+ (aq) + 2Cl-(aq) ----------> CaCl2(s)
