A chemical formula looks like this:
H2O (with 2 being an index meaning there are 2 hydrogen atoms, and you will notice an index by that its smaller than the coefficient, which is the normal sized number). H2O is obviously water
another example is H2SO4, which is sulfur acid. Both 2 and 4 are indexes meaning there are two hydrogen atoms (H) and 4 oxygen atoms (O)
2HCL is a third example, here we got no indexes just one coefficient, meaning we got 2 HCL molecules. HCL is the formula for salt acid.

How many H atoms are present in a chemical formula?
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.
How can one identify a base from its chemical formula?
To identify a base from its chemical formula, look for hydroxide ions (OH-) in the formula. Bases typically contain hydroxide ions, which give them their characteristic properties.

Why does fizzing occur in a reaction between copper ii oxide and sulphuric acid?
The chemical formula for copper (ii) oxide is CuO The chemical formula for Sulphuric acid is H2SO4. So a chemical reaction between them would look like this: CuO + H2SO4 -> CuSO4 + H2O
