subscripts are the cation superscripts are the anian
These subscripts are down the chemical symbol and at right. Example: O2
H2+ has a stronger bond than H2. The addition of a positive charge to the H2 molecule increases the attraction between the two hydrogen atoms, resulting in a stronger bond.

the number of the elements that is present in a compound
Be + 2 HCl -> BeCl2 + H2, in which the second and third instances of the number 2 should be subscripts when that font is available.

Balancing only allows you to change the coefficients, NOT the subscripts.

Do you mean subscripts like H2O (ie the 2 would be subscripted)?
If you mean Zn + H2SO4 --> ZnSO4 + H2, then no, it is not a decomposition reaction. In decomposition reactions one reactant is broken down into two or more simpler substances. For example, the electrolysis of water, 2H2O --> 2H2 + O2 is a decomposition reaction. The reaction referred to in your question is a double replacement (displacement) reaction. I apologize that the subscripts are not working at this time.
Some of the subscripts are used incorrectly
In a chemical formula, the significance of subscripts is that it tells you how many atoms of a certain element are present in a structure.
No, when the subscripts are changed, they become different compounds than the intended compounds.
You cannot.
The meaning of subscripts in a chemical formula is to indicate the number of a given atom in the molecule.
