2H2+O2 => 2H2O

Answer 2

@ParthKohli Can you help me?

Answer 3

the question ?

Answer 4

i mean what is the ques ?

Answer 5

Hydrogen gets oxidized (obviously, it has oxygen attach to it!) so that must mean that oxygen was reduced. In this instance, oxygen was the oxidizing agent and hydrogen the reducing agent. Nuff said?

Answer 6

you may always verify this fact by comparing oxidation numbers..

Answer 7

Oxidation is defined as the addition of oxygen or loss of electrons (LEO) and Reduction is the gain of electrons or addition of a proton. GER.

Answer 8

Oxidation happens to an atom when a more electronegative atom pulls electrons away from it. Oxygen is one of the most electronegative atoms, and you can check this by looking at the periodic table trends. Reduction is just the other side of the reaction. You can't have oxidation without reduction because one gives and one takes.

So no, oxidation isn't defined as the addition of oxygen, but it's nearly always true (you can oxidize oxygen) so generally we say that if you add oxygen you're oxidizing something because it will tend to pull electrons towards it, and if you add hydrogen you can consider it as reduction because it will donate electrons very readily.
