those are subscripts and mean that there are 2 hydrogen atoms and 1 sulfur atom and 4 oxygen atoms
because 2(H2)+4(SO4)=6x4(4 molecules of H2SO4)=24, there are 24 atoms in this molecule
H2SO4 is a chemical. I think you mean , 'What elements are in H2SO4'. They are Hydrogen (H) Sulphur(S) and Oxygen (O). H2SO4 is Sulphuric Acid. It is a combination of '-- 2 atoms of hydrogen 1 atom of sulphur 4 atoms of oxygen.
Pb + H2SO4 -> PbSO4 + H2
H+ and SO4 (2-) above the 4
The formula H2SO4 represents 7 atoms in a molecule: 2 H atoms, 1 S atom, and 4 O atoms.
H2SO4 is the molecular formula for Sulphuric Acid - Broken up the formula stands for this, 2 Hydrogen atoms, one Sulphur atom and 4 Oxygen atoms.

The formula H2SO4 represents 7 atoms in a molecule: 2 H atoms, 1 S atom, and 4 O atoms.
H2SO4 is sulphuric acid. The letters and numbers are: - 2 x H = 2 hydrogen atoms 1 x S = 1 sulphur atom 4 x O = 4 oxygen atoms. In strictest chemical terms , the numbers after the letter symbol should be written 'subscript'.
4H2SO4 = 4*(2(H)+1(S)+4(O)) = 4*(2+1+4) = 4*7 = 28 There are 28 atoms in 4 moles of H2SO4.
H2SO4 . This tells us that there are 2 hydrogen ato,ms, one sulphur atom and 4 oxygen atoms in a molecule of sulphuric acid .
Each molecule of the compound, H2SO4, contains the following elements: Hydrogen (2 atoms), Sulfur (1 atom) Oxygen (4 atoms).
The reaction is:C + 2 H2SO4 = CO2 + 2 SO2 + 2 H2O
