oxidation state on homonuclear molecules or elemental species = 0

Oxygen = -2 always

you can figure out the rest by balancing the charges

Alright, so for a i got 0, b -3, c -2, d 1, e 2, f -2 and g 0. Are these right?

Let me see if I get this right: You suggest that hydrogen in water have the oxidation number -3?

I believe so

-5? And in that equation, which element was reduced and which
was oxidized?

And can verify my answers please?

aluminum is right. again it does not have charge and is an elemental species.

Both hydrogens are positive one as well?

Yes. it is 2 times +1

Alright, so what about for e through g?

hello?

Sorry I was thinking. both e and g are wrong.

Not quite.

\[-1=-8+4+x\]
\[x=-1+8-4=3\]

So aluminum was reduced, so which was oxidized?

which one are you working on?

Awesome. so then which was oxidized and which was reduced?

I mean for all of the elements in the equations, it seems like aluminum gained electrons

we already did everything in the equation
