Question

Write the differences between balanced and unbalanced chemical equations.

Answer 1

I. balanced chemical reaction obeys the law of conservation of mass.

I. unbalanced chemical reaction does not obey the law of conservation of mass

Answer 2

__________________________

Balanced and unbalanced chemical equations :

Balanced chemical equation : The equation which contains an equal number of atoms of each element on both sides of the arrow is called a balanced chemical equation.

2Mg + O2 → 2MgO

A balanced chemical equation must obeys the law of conservation of mass.

Unbalanced chemical equation : The equation in which the number of atoms of each element on both sides of the arrow is not equal.

H2 + O2 → H2O
