The chemical formula (3H_2SO_4) represents three molecules of sulfuric acid. Each molecule of sulfuric acid contains 2 hydrogen (H) atoms, 1 sulfur (S) atom, and 4 oxygen (O) atoms. Therefore, in total, there are (3 \times 2 = 6) hydrogen atoms, (3 \times 1 = 3) sulfur atoms, and (3 \times 4 = 12) oxygen atoms. Overall, there are 6 hydrogen, 3 sulfur, and 12 oxygen atoms, totaling 21 atoms in (3H_2SO_4).

There are two elements, carbon and hydrogen.
Sulphuric Acid:- H2SO4 Aluminium Hydroxide:- Al(OH)3
The current periodic table contains 118 elements, as of April 2010, but many more may still be discovered.
There are two hydrogens in H2SO4. So there are six hydrogens in 3H2SO4.
There are 24 hydrogen atoms present in 3H2SO4. This calculation is done by multiplying the subscript of the hydrogen in H2SO4 (which is 2) by the coefficient in front of the compound (which is 3).
The balanced equation for aluminum reacting with sulfuric acid is 2Al + 3H2SO4 -> Al2(SO4)3 + 3H2.

When sulfuric acid reacts with hematite (iron oxide), it forms iron sulfate and water. The chemical equation for this reaction is: Fe2O3 (hematite) + 3H2SO4 (sulfuric acid) → Fe2(SO4)3 (iron sulfate) + 3H2O (water).
When aluminium reacts with sulphuric acid, it produces aluminium sulfate, hydrogen gas, and water. The balanced chemical equation for this reaction is: 2Al + 3H2SO4 → Al2(SO4)3 + 3H2. This is an example of a single displacement or redox reaction.
