Just took an a pex quiz
(I picked C and got it incorrect)
The coefficients of a balanced reaction. Hence, option D is correct.
A balanced equation is a chemical reaction in which the number of atoms for each element in the reaction and oxidation numbers are the same for both the reactants and the products.
To adjust the substance condition, you need to ensure the number of molecules of every component on the reactant side is equivalent to the number of particles of every component on the item side.
To make the two sides equal, we need to duplicate the number of particles in every component until the two sides are equivalent.
Hence, option D is correct.
