Question
**Assertion (A):** A balanced chemical equation obeys the law of conservation of mass. <br>**Reason (R):** The number of atoms of each element remains the same on both sides of a balanced equation.
Answer: A
💡 Solution & Explanation
Balancing ensures that every atom entering the reaction is accounted for in the products. Since the number of atoms is conserved, the total mass is also conserved. [1, 12]
