CHEM QUESTION PLEASE HELP?

According to the soubility rule :
1) compounds that are souble or mostly souble are (aq)
- group 1 from periodic table, NH4, chlorates, acetates, nitrates
- Halides (except Pb+2, Ag+, Hg+2
- Sulfate (except Ca+2, Sr2+, Ba 2+, Pb2+ and Hg2 2+
2) compound that are insouble (s)
- Hydroxides, sulfides (except for the rules above and group 2
sulfides
- Carbonates, phosphates, chromates,(except for above rules)

So in this case CO3 (carbonate) is part of number 2 which says that carbonate is a solid. Therefore the answer is Solid.

I would imagine a carbonate of any transition metal to be a solid. If that's what you ment by physical state?

Solid, this is represented by an (s) for state symbol equation.
