Answer 1

Answer:

The term oxidation was originally used to describe reactions in which an element combines with oxygen. Example: The reaction between magnesium metal and oxygen to form magnesium oxide involves the oxidation of magnesium. ... And, each O2 molecule gains four electrons to form a pair of O2- ions.

Answer 2

Answer:

$\boxed {\boxed{ \huge{ \blue{ \bold{ \underline{ANSWER}}}}}}$

Oxidation reactions can be defined in terms of addition of oxygen or the removal of hydrogen.

Examples: Addition of Oxygen:

(a). CuO(s) + H₂(g) → Cu(s) + H2O(l)

CuO adds oxygen to H₂; CuO is therefore the oxidizing agent or oxidant, it oxidizes the H₂ to H2O.

(b). C(s) + H2O(g) → H₂(g) + CO(g)

H2O is the oxidizing agent; it gives oxygen to carbon, which is oxidized to CO.
