The charge of b is +3 and the charge of o is -2. what is its formula?

a) b3o2

b) b2o3

c) o2b3

The formula is B2O3. The charges need to equal each other to obtain a neutral compound of no charge hence 2 B has a charge of +6 and 3 O has a charge of -6 to cancel out each other, resulting in a stable uncharged compound.

Option B: B2O3

In order to make a compound, it has to be neutral. We have to combine the +3 charged and the -2 charges until they cancel out.

The only possible compound is B2O3, since the positive charges add up to +6 and the negative charges add up to -6.
