Answer 1

Oxidation - : when oxygen is added & your hydrogen is removed then it is known as oxidation.
The explanation is in the attachment

Answer 2

Oxidation is the loss of electrons during a reaction by a molecule, atom or ion.

Oxidation occurs when the oxidation state of a molecule, atom or ion is increased. The opposite process is called reduction, which occurs when there is a gain of electrons or the oxidation state of an atom, molecule, or ion decreases.

An example of a reaction is that between hydrogen and fluorine gas to form hydrofluoric acid:

H2 + F2 → 2 HF

In this reaction, hydrogen is being oxidized and fluorine is being reduced. The reaction may be better understood if it is written in terms of two half-reactions.

H2 → 2 H+ + 2 e-

F2 + 2 e- → 2 F-

Note there is no oxygen anywhere in this reaction

or in simple wording

oxidation:-

addition of oxygen and removal of hydrogen is known as oxidation

reducation :- removal of oxygen and addition of hydrogen is known as reducation
