how do u complete these questions?

Question

2HCI(aq)+Pb(NO3)2(aq)--->
2HI(aq)+K2SO3(s)--->
Pb(NO3)2(aq)+2KCI(aq)--->
Ba(NO3)2(aq)+Na2SO4(aq)--->
K2CO3(aq)+Ba(NO3)2(aq)--->
HCI(aq)+AgNO3(aq)--->

Answer 1

2HCl(aq) + Pb(NO3)2(aq) ==> PbCl2(s) + 2HNO3(aq)

You need the solubility rules to do the others (except for #2. That one is
2HI(aq) + K2SO3(s) ==> H2SO3(aq) + 2KI(aq)
Here is the solubility chart.
