Question

identify from the following reactions the reactant that undergo oxidation and reduction

Answer 1

oxidation and reduction is not coming in class 10 board so in my school it is not taught yet but it will be after the course will be completed

Answer 2

Heya!!

------------------------------------

Oxidation means addition of O2 or removal of H2 gas while reduction means removal of O2 or addition of H2 gas.

1. Fe + S - > FeS
This reaction is not redox reaction.

2. 2Ag2 O - > 4Ag + O2
In this reaction, silver oxide gets reduced.

3. 2Mg + O2 - > 2MgO
In this reaction, magnesium gets oxidized.

4. NiO + H2 - > Ni + H20
In this reaction, nickel oxide (NiO) gets reduced.

Hope it helps uh :)
