2H2O

Answer 1

The molecule that shows two atoms of hydrogen (H) is **2H2O**.

Here's a breakdown of the options:

1. **2CH4**: This indicates 2 molecules of methane, which has a total of 8 hydrogen atoms (2 x 4 H).
2. **H2SO4**: This molecule has 2 hydrogen atoms.
3. **HO2**: This molecule has 1 hydrogen atom.
4. **2H2O**: This indicates 2 molecules of water, which has a total of 4 hydrogen atoms (2 x 2 H).

Therefore, both **H2SO4** and **2H2O** can represent two atoms of hydrogen, but if you strictly need to identify a single molecule with two hydrogen atoms, **H2SO4** is the best representation. However, in the context of numbers, **2H2O** has more than two hydrogen atoms.

If you are specifically looking for an answer with **only** two hydrogen atoms, then **H2SO4** is correct.
