If anyone could verify the net ionic equations I put up on here for me, and tell me what I'm doing wrong, that would be great!
Sn(NO3)2aq + 2NaOHaq -> Sn(OH)2s + 2NaNO3aq
Net: Sn2+aq + 2OH1-aq -> Sn(OH)2s
2NaOHaq + K2SO4aq -> Na2SO4aq + 2KOHaq
Net: 2Na1+aq + 2OH1-aq + 2K1-aq + SO42-aq -> 2Na1+aq + SO4^2-aq + 2K1-aq + 2OH1-aq
Na2Saq + Cu(C2H3O2)aq ->2Na(C2H3O2)aq + CuSs
Net: S2-aq + Cu2+[aq] -> CuSs
