Question

On what basis is a chemical equation balanced?

Answer 1

Hey!!!

In chemical reactions the number of atoms of an element or molecule is equal to the number of atoms of the same atom or molecule in the reactant side.

Number of moles can also be taken into consideration....

HOPE IT HELPS.....

Answer 2

Chemical equation is balanced on the basis of law of conservation of mass, i.e. number of atoms of the elements on the left side(reactants) should be equal to number of atoms of same elements on right side(products).

example - Mg + o↓2  = Mgo

AFTER BALANCING

2 Mg + o↓2  = 2Mgo
