Question

which of the following molecules shows two atoms of hydrogen (H)
H2SO4
2CH4
2H2O
HO2

Answer 1

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

1. **H2SO4**: This molecule has 2 hydrogen atoms (H).
2. **2CH4**: This represents 2 molecules of methane, each containing 4 hydrogen atoms, totaling 8 hydrogen atoms (2 × 4 = 8).
3. **2H2O**: This represents 2 molecules of water, each containing 2 hydrogen atoms, totaling 4 hydrogen atoms (2 × 2 = 4).
4. **HO2**: This molecule contains 1 hydrogen atom.

Based on this breakdown, **H2SO4** is the only molecule that has exactly two hydrogen atoms.
