Question

Assertion : A chemical equation should be balanced.
Reason : Number of atoms of each element should be
same on reactants as well as products side.

Answer 1

Answer:

ASSERTION IS TRUE

Explanation:

A BALANCED CHEMICAL EQUATION SIGNIFIES THE REACTANS AND PRODUCTS HAVE SAME NUMBER OF ATOMS ACCORDING TO LAW OF CONSERVATION OF MASS, MASS CAN NEITHER BE CREATED NOR DESTROYED.

HOPE THIS HELPS

Answer 2

The answer is- Both Assertion and Reason are correct but the reason is not the correct explanation of the assertion.

EXPLANATION

• The above problem can be simply explained as follows.
• A balanced chemical reaction is one in which there are equal number of atoms on both side of the chemical reaction.
• Mass of the reactant and product must be equal in a reaction.
• According to the law of conservation mass- since energy can neither be created nor be destroyed, mass in a closed system should remain constant.
• For example - The reaction between Oxygen and Magnesium is shown as -

2Mg + O₂ ----------> 2MgO

• It can be seen that that atoms of manganese and oxygen are equal on both the sides.
