Question

Which of these is/are conserved during a chemical reaction?
A. Mass only
B. Charge only
C. Both mass and charge
D. Neither mass nor charge

Answer 1

Answer:

a). mass only

Explanation:

mass neither be destroyed neither be created

Answer 2

Both Mass and Charge are conserved during a chemical reaction. Hence the correct option is (C.) Both Mass and Charge.

• According to the Law of Conservation of Mass, mass can neither be created nor be destroyed during a chemical reaction, it can only be converted from one form to another. Therefore, the total mass of the reactants is always equal to the total mass of the products.
• According to the Law of Conservation of Charge, the charge always remains conserved. The law states that the total electric charge in a closed system remains constant and cannot be created or destroyed, but it can only be transferred from one object to another or transformed into different forms.
• Hence during a chemical reaction both charge, as well as mass, are conserved. Hence the correct option is (C.) Both Mass and Charge.
