Question

Giving examples state the difference between balanced and unbalanced chemical equations

Answer 1

__________________________

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

Answer 2

Explanation:

Balanced Chemical Equation :

A balanced chemical reaction is that in which the total number of atoms of each element are equal on both sides of the equation.

Example :

2H2 + O2 ➡️ 2H2O

Unbalanced Chemical equation :

An unbalanced chemical equation is a one in which the number of moles of each element in the reaction is not equal to the number of moles of the corruspounding element in the product.

Example :

H2 + O2 ➡️ H2O
