5-13-2. What is the net ionic equation for the reaction between
HF(aq) and Ca(OH)2(aq)?
A. 2 HF(aq) + Ca(OH)2(aq) → 2 H2O(l) + CaF2(s)
B. 2 H+(aq) + 2 F-(aq) + Ca2+(aq) + 2 OH-(aq) → 2 H2O(l) +
2F-(aq) + Ca2+(aq)
C. 2 HF(aq) + Ca2+(aq) + 2 OH-(aq) → 2 H2O(l) + 2F-(aq) + Ca2+(aq)
D. 2 HF(aq) + Ca2+(aq) + 2 OH-(aq) → 2 H2O(l) + CaF2(s)



5-13-3. What is the net ionic equation for the reaction between
HNO3(aq) and NH3(aq)?
A. HNO3(aq) + NH3(aq) → NH4NO3(aq)
B. H+(aq) + NO3-(aq) + NH3(aq) → NH4+(aq) + NO3-(aq)
C. H+(aq) + NH3(aq) → NH4+(aq)



5-13-4. What is the net ionic equation for the reaction between
Mg(OH)2 in milk of magnesia with HCl (in stomach acid)? The complete formula equation is:
Mg(OH)2 + 2 HCl → MgCl2 + 2 H2O
A. Mg2+ + 2 OH- + 2 H+ + 2 Cl- → Mg2+ + 2 Cl- + 2 H2O
B. Mg(OH)2 + 2 H+ + 2 Cl- → Mg2+ + 2 Cl- + 2 H2O
C. H+ + OH- → H2O
D. Mg(OH)2 + 2 H+ → Mg2+ + 2 H2O
