Answer 1

The reactions are written in each case:

a) Molecular:

Ba (OH) 2 (aq) + 2 HCl (aq) = BaCl2 (aq) + 2 H2O (l)

Complete:

Ba + 2 + 2 OH- + 2 H + + 2 Cl- = Ba + 2 + 2 Cl-2 = 2 H2O

Net:

OH- + H + = H2O

b) Molecular:

3 HClO3 (aq) + Fe (OH) 3 (aq) = Fe (ClO3) 3 (aq) + 3 H2O (l)

Complete:

3 H + + 3 ClO3- + Fe + 3 + 3 OH- = Fe + 3 + 3 ClO3- + 3 H2O

Net:

H + + OH- = H2O

C) Molecular:

NH3 (aq) + HI (aq) = NH4 + (aq) + I- (aq)

Complete:

NH3 + H + + I- = NH4 + + I-

Net:

NH3 + H + = NH4 +
