Question

oxidation number of H5P3O10​

Answer 1

Answer:

The sum of the oxidation numbers of a species that is not ionic must equal 0.

Oxygen is always given a -2.

Hydrogen is almost always given a +1.

Answer 2

H5p3o10

H = + 1, 0 = -2

So,

5(+1) + 3(P) + 10(-2) = 0

3P - 15 = 0

3P = +15

P = +5
