Question

Responses

2H2O
2 cap h sub 2 cap o

2CH4
2 cap c cap h sub 4

HO2
cap h cap o sub 2

H2SO4

Answer 1

To determine which of the listed molecules contains two atoms of hydrogen (H), we can analyze each option:

1. 2H2O (2 water molecules) - Each water molecule (H2O) contains 2 hydrogen atoms. Therefore, 2H2O contains \( 2 \times 2 = 4 \) hydrogen atoms.

2. 2CH4 (2 methane molecules) - Each methane molecule (CH4) contains 4 hydrogen atoms. Therefore, 2CH4 contains \( 2 \times 4 = 8 \) hydrogen atoms.

3. HO2 (hydrogen peroxide) - This molecule contains only 1 hydrogen atom and 2 oxygen atoms. So, it contains 1 hydrogen atom.

4. H2SO4 (sulfuric acid) - This molecule contains 2 hydrogen atoms, along with 1 sulfur and 4 oxygen atoms.

Out of all the options presented, H2SO4 is the only molecule that contains exactly two atoms of hydrogen.
