The Question is incomplete here is the complete question " Suppose an iron atom in the oxidation state +3 formed a complex with three hydroxide anions and three water molecules. Write the chemical formula of this complex.
Answer:
{Fe(OH)3(H20)3}
Explanation:
Oxidation state is the electron gained or lost by and atom, So if iron is in +3 state in formula it must have lost three electron.
We know that OH posses the oxidation state of -1 and water have zero oxidation state. SO, Let's take iron equal to y and find its oxidation state in the formula
y + 3 ( - 1 ) + 3 ( 0 ) = 0
y - 3 + 0 = 0
y-3=0
y= + 3
Hence it's proved that iron has +3 oxygen state.

A
because B. should be aluminum (III) ion
C. should be K, not P
D. iron is Fe not I
Do you need us to balance it?
Answer:
Atmospheric nitrogen is not heavier than chemical nitrogen, largely because “chemical nitrogen” is ultimately derived from atmospheric nitrogen. On the other hand, you could be asking why the atomic mass of nitrogen is not the same as the mass of nitrogen gas; that's because gaseous nitrogen is diatomic, .
