Answer:
Coefficients.
Explanation:
A general chemical reaction is given by:
aA + bB → cC + dD
Where a, b, c, and d are the stoichiometric coefficients. In a balanced equation, they will be written, so the amount of the elements will be equal on each side of the equation. The coefficient multiplies the atoms.
A subscript is a number that follows a letter below it, and in a chemical formula, it represents how much of that element is presented in the compound. For example in O₂, the subscript 2 represents that are two atoms of oxygen in the molecule.
A superscript follows the letter or number above it, and in an equation, it represents exponentiation: the number will be multiplied by itself the number times of the superscript. For example, in 5², the two represent that the 5 must be multiplied by itself two times: 5x5 = 25.
