Tutor's home Rahul taught math to my 9th grader. He took the effort to understand what chapters was difficult for him and prepared custom material for him. It helped my son a lot. I will recommend him any day.

The law followed when balancing a chemical equation is the "law of conservation of mass." This law states that mass is neither created nor destroyed in a chemical reaction; it is conserved. In other words, the total mass of the reactants must equal the total mass of the products.
When balancing a chemical equation, you adjust the coefficients (the numbers in front of the chemical formulas) to ensure that the number of atoms of each element on both sides of the equation is the same. This balancing process maintains the conservation of mass.
b)
6Na + 6H3O → 6NaOH + 3H2
Now, the equation is balanced. The number of each type of atom on both sides of the equation is the same, and the law of conservation of mass is upheld.

The equation is indeed balanced in terms of the number of atoms of each element. Therefore, Assertion (A) is correct.
Reason (R) states that the law of conservation of mass holds good for a chemical equation. This is also correct. The law of conservation of mass is a fundamental principle in chemistry, which states that the total mass of the reactants in a chemical reaction is equal to the total mass of the products. In other words, mass is neither created nor destroyed in a chemical reaction; it is conserved.
Since both Assertion (A) and Reason (R) are correct, they are related, and Reason (R) provides a valid explanation for Assertion (A).
