Question

The overall charge of any compound is going to be zero. Ag has a charge of +1 and CO3 has a charge of -2. If we add the charges for only one of each ion together +1 + -2 = -1. But -1 cannot be the charge of the compound, so how many more Ag+1 should we add to make the charge = 0? If we have 2 Ag+1 and 1 CO3-2, let’s add those charges together. +1 + +1 + -2 = 0. So we have to have two Ag+1 and one CO3-2 to make a compound. What does that look like?

Answer 1

The compound would be written as Ag2CO3

Answer 2

That look like that the compound is Ag2CO3

Step-by-step explanation:

Ag2CO3 is an ionic compound. It's composed by two Ag+1 (each one with one positive charge) and one CO3-2 (with two negative charges) so that the overall charge of the compound is zero. The addition of charges is 2*1 + (-2) = 0.
