Question

2.
All the chemical equations must be balanced. Why ? Guess and write.
​

Answer 1

Answer:

The chemical equation needs to be balanced so that it follows the law of conservation of mass. A balanced chemical equation happens when the number of the different atoms of elements on the reactants side is equal to that of the products side. Balancing chemical equations is a process of trial and error.

Answer 2

All the chemical equations must be balanced to follow law of conservation of matter.

• Law kf conservation states that matter can neither be created nor be destroyed.
• A balanced chemical equation consists of equal number of atoms on both the sides of the equation and follows the law of conservation of matter.
• If balanced equations are not used then it represents that the law of conservation of matter will be violated because there will be unequal number of atoms on both sides of the reaction which would be incorrect.
