N₂0₃

what is the oxidation number

Answer / explanation:

The oxidation number of N2O3

The oxidation number of O = - 2

The oxidation number of N = x

Since there are 2 moles of N

And 3 moles of O

Therefore,

2 * x + (-2 * 3) = 0

2x + (-6) = 0

+ * - = -

2x - 6 = 0

Find x, divide both sides by 2

2x = 6

2x / 2 = 6/2

2 cancels 2

x = + 3

The negative or positive sign is very important, so it must be added.
