By looking at an actual chemical formula for a compound, we could tell you how many hydrogen atoms there are per molecule (or at least per formula unit) of that compound.Without the specific chemical formula, we can't. So the question is meaningless ... how many hydrogen atoms are present in a chemical formula depends on what the chemical formula is.
When a water molecule is being taken from the equation, that represents condensation synthesis, also known as dehydration synthesis. When a water molecule is being added to the equation, it represents hydrolysis.
VSEPR predict the geometry of a chemical molecule.
The chemical formula of a compound does not indicate the structure of the molecule, such as the ways in which the atoms are bonded to one another. For example, CO2 is the chemical formula for carbon dioxide, but doesn't tell you how the atoms are bonded together. The structural formula of carbon dioxide is O=C=O. Now we can see that the carbon atom is in the middle, and the two oxygen atoms both form a double bond with the central carbon atom, and not to each other. It also shows that it is a linear molecule.
Yes, chemical equations describe chemical reactions. A chemical equation tells you what substances are reacting, what substances are produced and, in a balanced equation, provides the coefficients to tell us in what ratio the substances react or are produced.
What and how many elements it's composed of
A chemical formula tells you the number of each type of atom in the molecule or structure.
It tells what elements are present in a molecule and how many atoms of each element are present.
That each molecule contains 1 atom of carbon and 4 atoms of hydrogen.

the purpose of a subscript is to tell how many atoms of that chemical is used in the formulaThe number of atoms of the same element in the molecule ~APEX

that it has 3 of them

A compound formula, or molecular formula, tells you about the chemical composition of the substance in terms of the number of atoms of that element that are present. From there, the empirical formula may also be derived by simplifying the molecular formula, as well as its structural formula.
