Final answer:
The molecular equation and net ionic equation for the given reactions are provided.
Step-by-step explanation:
For part a, the molecular equation for the reaction AgNO3 + Hl is AgNO3(aq) + Hl(aq) → Agl(s) + HNO3(aq). The net ionic equation is Ag+(aq) + I-(aq) → Agl(s).
For parts b and c, both reactions will not occur. The molecular equations for these reactions are:
b. Ba(NO3)2(aq) + K2CO3(aq) → NR
c. Mg(NO3)2(aq) + K2SO4(aq) → NR
