Which are the expected types and total numbers of atoms in the products of this chemical reaction? h2so4 a. 1 sulfur atom and 3 oxygen atom b. 2hydrogen atoms and 1oxygen atom c. 1 hydrogen atom, 1 sulfur atom, and 1 oxygen atom d. 2 hydrogen atoms, 1 sulfur atom, and 4 oxygen atoms

So when given a chemical formula, the subscripts directly in front of the atom correspond to the amount of atoms in that compound. So we have .

There's a 2 in front of hydrogen (H), so there are 2 atoms of Hydrogen.

There are no numbers in front of sulfur (S), so it is assumed to be 1.

There is a 4 in front of oxygen (O), so there are 4 atoms of oxygen present.

So overall, the answer is D) 2 hydrogen atoms, 1 sulfur atom, and 4 oxygen atoms.
