Question

Identify the oxidising agent; 2Mg + O2 --------- 2MgO. Also explain it.

Answer 1

Here the oxidizing agent is Mg and the reducing agent is the O2.

This is because Mg is getting taking in O and is reducing itself to form MgO.

This Magnesium oxide, or magnesia, so formed is a white hygroscopic solid mineral that occurs naturally as percales and is a source of magnesium.

Answer 2

Answer:

Explanation:Oxidation is the process of loss of electrons whereas Reduction is the process of gain of electrons.

An element that is oxidized is a reducing agent, because the element loses electrons, and an element that is reduced is an oxidizing agent, because the element gains electrons

An oxidizing agent is gains electrons and A reducing agent is loses electrons

And here Oxygen gain electron from magnesium to complete the octet and magnesium lose electron to complete its octet...

So here Oxygen is reduced so it is oxidising agent and magnesium is oxidised so it is reducing agent...

Hence you clear as SPRITE
