Question

Mention the chemical equation of reaction between the Mg and O2 and write its physical state of reactants and products??​

Answer 1

Answer:

2Mg + O2 = 2MgO

Explanation:

Physical states of Mg is Solid and of O is gaseous and that of product's (MgO) is solid

Answer 2

When a magnesium is heated, it burns in air with a dazzling white flame to form a white powder called magnesium oxide. Magnesium combines with oxygen present in air to form magnesium oxide.

Magnesium + oxygen → Magnesium oxide.

The burning of magnesium in air to form magnesium oxide is an example of a chemical reaction . In this chemical reaction there are two reactants ' magnesium and oxygen ' but only one product ' magnesium oxide '. The properties of the product magnesium oxide are entirely different from those of the reactants magnesium and oxygen.

Representation of the reaction in form of chemical equation :

• Magnesium → Mg

• Oxygen → $\sf{O_2}$

• Magnesium Oxide → MgO

$\sf{Mg + O_2 = MgO}$

Balanced :-

• $\sf{2Mg + O_2 = 2MgO}$

Physical states of these reactants and products are :-

• Magnesium → Mg ( In Solid State)

• Oxygen → $\sf{O_2}$ ( Gaseous State)

• Magnesium Oxide → MgO ( In Solid State Or White powder)
