To determine which of the given molecules shows two atoms of hydrogen (H), let's analyze each option:
1. **2CH4**: This is two molecules of methane. Each CH4 molecule contains 4 hydrogen atoms, so 2CH4 will have \(2 \times 4 = 8\) hydrogen atoms.
2. **HO2**: This molecule contains one hydrogen atom (H) and two oxygen atoms (O), so it has 1 hydrogen atom.
3. **H2SO4**: This molecule includes 2 hydrogen atoms (H), 1 sulfur atom (S), and 4 oxygen atoms (O). Therefore, it has 2 hydrogen atoms.
4. **2H2O**: This represents two molecules of water. Each H2O molecule has 2 hydrogen atoms, so 2H2O will have \(2 \times 2 = 4\) hydrogen atoms.
Based on the analysis, both **H2SO4** and **HO2** contain hydrogen atoms, but only **H2SO4** has exactly two hydrogen atoms.
So, the correct answer is **H2SO4**.
