To determine which molecule contains two atoms of hydrogen (H), we can analyze the given options:
1. **2CH4**: This indicates two molecules of methane (CH₄), which has 4 hydrogen atoms per molecule. Thus, it contains **2 × 4 = 8 hydrogen atoms**.
2. **2H2O**: This indicates two molecules of water (H₂O), which has 2 hydrogen atoms per molecule. Thus, it contains **2 × 2 = 4 hydrogen atoms**.
3. **H2SO4**: This molecule, sulfuric acid, has 2 hydrogen atoms, since it is represented as H₂.
4. **HO2**: This molecule contains 1 hydrogen atom (H) and 2 oxygen atoms (O), totaling **1 hydrogen atom**.
The correct answer is **H2SO4**, which shows **two atoms of hydrogen (H)**.
