What do the sub scripts in a chemical equation tell about the equation?
The subscript denotes how much of that atom is in the molecule.
Do you have to use subscript in chemical formulas?
Not every chemical formula requires subscript. For example table salt is NaCl, sodium chloride. No subscript. But most chemical formulae do require subscript, such as water, H2O.

What does 3 types of subscript tell you?
- the atomic number of a chemical element or- the number of a type of an atom in a molecule or- indices for physical/chemical parameters
What do the subscript and coefficent in a chemical equation tell us?
The subscript in a chemical equation tells us the ratio of atoms of each element present in a compound. The coefficient tells us the number of molecules or formula units involved in the reaction.
What does a subscript in a chemical formula represents?

What do the subscript numbers represent in a chemical formula?
They tell you how often an atom - or a group of atoms - are repeated.
What is the subscript is the chemical expression of dihydrogen oxide?
The chemical formula of dihydrogen oxide is H2O. This means that the subscript for hydrogen in this chemical expression is 2.
