Answer 1

__Agl+__Fe2(CO3)3--> __Fel3+__Ag2CO3

You're just making these things hard on yourself..

1.Look at CO3 on the left. There are 3 so add a 3 on the right for Ag2CO3.
2. That means 6 Ag so place a 6 for AgI on the left.
3. That means 6I so 2 FeI3 on the right.
4. I didn't check and I ALWAYS do but I'll leave it for you to check.
