H2SO4

Answer 1

To determine which of the given molecules contains two atoms of hydrogen (H), let's analyze each option:

1. HO2: This molecule contains one hydrogen atom (H).
2. 2H2O: This means there are two water molecules. Each water molecule (H2O) has two hydrogen atoms, so 2H2O has a total of 2 x 2 = 4 hydrogen atoms.
3. 2CH4: This means there are two methane molecules (CH4). Each methane molecule has four hydrogen atoms, so 2CH4 has a total of 2 x 4 = 8 hydrogen atoms.
4. H2SO4: This molecule contains two hydrogen atoms, as indicated by the "H2" at the beginning of the chemical formula.

The only correct response showing exactly two atoms of hydrogen is H2SO4.
