Question

What is not represented by a balanced chemical equation?

A. The formulas for all substances are correct.
B. The same subscripts are on each side of the equation.
C. The same mass is represented on each side of the equation.
D. The same number of atoms are on each side of the equation.

Answer 1

The correct answer is:

B) The same subscripts are on each side of the equation.

Answer 2

Answer: The correct answer is Option B.

Step-by-step explanation:

A balanced chemical equation follows law of conservation of mass.

This law states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form. This means that total mass on the reactant side is equal to the total mass on the product side.

This also means that the total number of individual atoms on the reactant side will be equal to the total number of individual atoms on the product side.

For Example: Reaction of hydrochloric acid with sodium hydroxide, the equation follows:

`HCl+NaOH\rightarrow NaCl+H_2O`

From the above chemical equation, the chemical formula for the substances are written correctly on both the sides of the reaction. But the subscript of hydrogen on the reactant side is 1 and on the product side is 2.

Thus, the correct answer is Option B.
