_Al(s) + - 02(g) → _Al2O3 (s)<br> Balance equation
AfilCa [17]
<h2>Al (s) +   O₂ (g)----> Al₂O₃(s)</h2>

Explanation:

Chemical reaction

When two or more substances react and form some new substance it is called as chemical reaction .

For example :

Al (s) +   O₂ (g)----> Al₂O₃(s)

Chemical equation

It is the representation of chemical reaction in terms of symbols ,molecular formulas ,moles , states  etc .

As we know all chemical reaction obeys law of chemical combination therefore chemical reaction need to be balanced .  

Law of conservation of mass

Mass can neither be created nor be destroyed in a chemical reaction , it is always conserved .That is why reactions need to be balanced .

Let us balance

Al (s) +   O₂ (g)----> Al₂O₃(s)

After balancing , it becomes :

2Al (s) +   3/2O₂ (g)----> Al₂O₃(s)
