A subscript in a balanced chemical equation indicates the number of atoms of an element present in a molecule. It is a small number that appears at the bottom right of the element's symbol. Balancing the equation ensures that the number of atoms of each element is the same on both sides of the equation.
Subscripts in a chemical formula represent the number of each atom present in a compound. Changing a subscript without changing the corresponding coefficients in a balanced chemical equation would alter the chemical formula and lead to an unbalanced equation. To balance the equation, adjust the coefficients in front of the compounds rather than changing the subscripts.

The subscript 2 in a chemical equation typically indicates that there are two atoms of that element present in the compound or molecule. It represents the stoichiometry of that element within the compound.
The balanced chemical equation for potassium chloride is 2KCl = 2K + Cl2.
The balanced chemical equation for copper sulfate is: CuSO4 + H2O → CuSO4•5H2O
Subscripts in a chemical formula represent the number of each atom present in a compound. Changing a subscript without changing the corresponding coefficients in a balanced chemical equation would alter the chemical formula and lead to an unbalanced equation. To balance the equation, adjust the coefficients in front of the compounds rather than changing the subscripts.
A balanced chemical equation has correct placed coefficients and a representative chemical equation need these coefficients.

Proteins have a very complicate chemical formula but not a "balanced chemical equation".
The subscript is mentioned only in a chemical formula.3 FeCl3 in a chemical reaction is not similar to Fe3O4 in a chemical formula.
The subscript 2 in a chemical equation typically indicates that there are two atoms of that element present in the compound or molecule. It represents the stoichiometry of that element within the compound.
Do not try this! 2Na +2HCl --> 2NaCl + H2 The last 2 should be a subscript.
The balanced chemical equation for potassium chloride is 2KCl = 2K + Cl2.
The subscript denotes how much of that atom is in the molecule.
How does a subscript affect the element just before it?
No, the chemical equation is not balanced. The correct balanced equation is 2SO2 + O2 → 2SO3.
