Question

Please help! I really need help with this.

The name listed for C2(CO3) is incorrect please give an explanation of what the correct name would be. And no the formula isn't supposed to be Cr2(CO3)3 so I'm just confused.

Answer 1

Should just be CrCO3

Step-by-step explanation:

The (II) in Chromium (II) Carbonate is referring to the charge. The Chromium ion with a 2+ charge balances with Carbonate's 2- charge, meaning no extra ions need to be added.
