Is this the correct equation for the formation of [Co(NH3)5(ONO)]^2+ from [Co(NH3)5Cl]^2+ ...

[Co(NH3)5Cl]^2+ + NO2 --> [Co(NH3)5(ONO)]^2+ + Cl-

I'm a bit unsure because the charges don't balance

Check the sign on NO2 on the left. I think it should be -1.

To determine if the given chemical equation for the formation of [Co(NH3)5(ONO)]^2+ from [Co(NH3)5Cl]^2+ is correct, we need to ensure that the charges are balanced on both sides of the equation.

First, let's analyze the charges on the reactant side of the equation:
- [Co(NH3)5Cl]^2+ has a charge of +2.
- NO2 (nitrite ion) typically has a charge of -1.

Now, let's analyze the charges on the product side of the equation:
- [Co(NH3)5(ONO)]^2+ has a charge of +2.
- Cl- has a charge of -1.

Based on this analysis, we observe that the charges are not balanced. The reactant side has a total charge of +2 from [Co(NH3)5Cl]^2+ and -1 from NO2, resulting in a net charge of +1. On the other hand, the product side has a total charge of +2 from [Co(NH3)5(ONO)]^2+ and -1 from Cl-, resulting in a net charge of +1.

To balance the charges, we need to make sure that the total charge on the reactant side is equal to the total charge on the product side. In this case, since the net charge is already +1 in both cases, we can conclude that the given equation is balanced as it is.
