The coefficients in a balanced chemical equation are important because they give the ratio of the reactants and the products.
Those ratios are fixed and when the reagents react do it in the same proportion and yield the products in the same proportion of the coefficients.
Then, the coefficients are the basis for the calculations of the amount of substances that react and the amount of substances that are formed as result of the reaction.
Answer:
neutrons
Explanation:
Atomic number : It is defined as the number of electrons or number of protons present in a neutral atom.
Mass number is the number of the entities present in the nucleus which is the equal to the sum of the number of protons and electrons.
Mass number = Number of protons + Number of neutrons
Thus both C14 and C12 have same number of protons as they have same atomic number.
The difference in the mass number of both the isotopes is sue to the difference in the number of neutrons.
Atomic number = Number of protons = 6
For CC- 14, Number of neutrons = 14 - 6 = 8
For C 12, Number of neutrons = 12 - 6 = 6
