Question

Assign oxidation numbers to each atom in the following compounds: HI, PBr3, GeS2, KH, As2O5, H3PO4 (the numbers should be subscripts)

Answer 1

Do you have the seven rules?

I will go over one ..
H3PO4
Rule: H is +1
Rule: O is -2 except in peroxides.
Rule: The sum of the oxidation numbers in a compound is zero.
3+ P -8=0 which makes P + 5

Try some yourself, memorize the rules. We will check your work.
