Abalanced chemical equation indicates both the number of particles of reactants and products and the number of
a. orbits.
c. nuclei.
b. electrons.
d. moles

Option (d) is the correct answer.

Explanation:

A chemical reaction equation that shows same number of reactants and products is known as a balanced chemical equation.

For example,

Here, number 2 placed before the sodium (Na) atoms depicts that 2 moles of sodium reacts with 1 mole of chlorine to give 2 moles of sodium chloride salt.

Therefore, in a balanced chemical reaction equation number of moles are also equal on both reactant and product side.

Thus, we can conclude that a balanced chemical equation indicates both the number of particles of reactants and products and the number of moles.
