Chemical formulas are made of symbols representing elements and subscripts indicating the number of atoms of each element in a molecule.
subscripts
No - they are usually balanced by changing the numbers before the molecules.
The chemical symbol for heroin is C21H23NO5. Its chemical formula represents the specific elements and their proportions in a single molecule of heroin. Chemical formulas are used to identify and represent the composition of substances, which is important in understanding their properties and behavior.
No, subscripts cannot be changed in a chemical formula to balance a chemical equation. Balancing a chemical equation involves adjusting the coefficients in front of the chemical formulas to ensure that the number of each type of atom is the same on both sides of the equation. Changing subscripts would alter the chemical identities of the substances involved.

indicate the number of atoms or ions in a single unit
Changing subscripts in a chemical formula changes the actual chemical species present, leading to a different reaction. Subscripts represent the ratio of elements in a compound and should not be changed to balance chemical equations. Balancing equations is done by adjusting coefficients in front of chemical formulas, not by changing subscripts.

Subscripts are most familiar to use in the writing of chemical formulas such as H2O -- the 2 should be a subscript -- and in mathematics you will see variables with subscripts.
Compounds are represented by chemical formulas, which show the types and numbers of atoms present in the compound. These formulas can be written using chemical symbols for individual elements and subscripts to indicate the number of atoms. Examples include H2O for water and CO2 for carbon dioxide.
