Answer 1

Mg + O2 --- 2Mgo

it is a combination reaction or oxidation reaction.

Answer 2

Answer :

The chemical reaction which takes place when Magnesium wire is burnt in air is Combination Reaction. Another type of reaction also takes place which is called Exothermic Reaction because heat or energy gets released when it is burnt in air.

The reaction is given below :

2Mg + O2 -------> 2MgO

Here, magnesium wire is in metal form so it burns in air without any kind of difficulties. In the reaction we can see clearly that magnesium reacts with oxygen to give white powdery substance called Magnesium Oxide(MgO).
