Solution

The correct option is A

True


The statement 'The Chemical equation doesn't change if all its coefficients are multiplied by a common natural number' is true.

Example: Consider the following equations which has the coefficients of Zn, HCl, ZnCl2 and H2 respectively as 1, 2, 1, and 1 respectively.

Zn+2HClZnCl2+H2

If we multiply all the coefficients by a number 3, the equation remains balanced.

3Zn+6HCl3ZnCl2+3H2

The chemical reaction doesn't change, only the molecules involved in the reaction increase by three times.
