PLEASE HELP ME LAST QUESTION ON TEST
When balancing a chemical equation, one uses all of the following principals except...

Select one:
a. The number of atoms of each element on the reactant side of the equation must equal the number of atoms of each element on the product side of the equation.
b. Subscripts in a formula may be changed so that the equation is balanced.
c. The coefficients for the reactants and products may be changed to balance the equation.
d. The law of conservation of matter must be obeyed.

Respuesta :

The chemical equation is said to be balanced if the number of the atom of the reactant element is equal to that of the product. In balancing the reactions, subscripts in a formula are never changed. Thus, option b is correct.

What is a balanced reaction?

A balanced chemical reaction is a representation of the elements along with their coefficients and charges in a proportional manner on the reactant and the product side.

To balance a reaction the coefficients for the reactants and products are varied, followed by the law of conservation of matter. In balancing the subscripts in the elemental formula are never changed.  

Therefore, option b. the subscripts of the elemental formula are never changed.
