To determine which molecules contain two atoms of hydrogen, let's analyze each option:
a. **2CH4** - This represents 2 molecules of methane, which contains 4 hydrogen atoms per molecule. Therefore, 2CH4 has 2 × 4 = 8 hydrogen atoms.
b. **HO2** - This molecule consists of 1 hydrogen atom and 2 oxygen atoms, so it has 1 hydrogen atom.
c. **2H2O** - This represents 2 molecules of water, which contains 2 hydrogen atoms per molecule. Therefore, 2H2O has 2 × 2 = 4 hydrogen atoms.
d. **H2SO4** - This is sulfuric acid, which contains 2 hydrogen atoms, along with 1 sulfur atom and 4 oxygen atoms.
Based on this analysis, the correct answer is:
**d. H2SO4**, as it contains exactly 2 hydrogen atoms.
