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

  1. 2H2O - This represents two molecules of water (H2O). Each water molecule contains two hydrogen atoms, so this represents a total of \(2 \times 2 = 4\) hydrogen atoms.

  2. H2SO4 - This molecule (sulfuric acid) contains two hydrogen atoms, as indicated by the "H2" in the formula.

  3. HO2 - This molecule contains only one hydrogen atom, as indicated by the single "H".

  4. 2CH4 - This represents two molecules of methane (CH4). Each methane molecule contains four hydrogen atoms, so this represents a total of \(2 \times 4 = 8\) hydrogen atoms.

Based on the above analysis, the molecules that contain exactly two hydrogen atoms are:

  • H2SO4

So, the correct response is: H2SO4
