Answer 10

When I searched it says this

Answer 11

Or this

Answer 12

If the
oxidation numbers
of the individual elements as reactants change upon reaction.

Explanation:
Oxidation numbers are theoretical constructs and have marginal physical significance. Formally, the oxidation number of an element in a compound is the charge the element would have if all the bonding electrons were broken, with the charge assigned to the most electronegative atom.

Answer 13

Thanks, that is more towards the chemical side of things, but I can research the visual side.
