Question

Which of the following molecules shows two atoms of hydrogen (H)?(1 point)
Responses

2CH4
2 cap c cap h sub 4

2H2O
2 cap h sub 2 cap o

HO2
cap h cap o sub 2

H2SO4

Answer 1

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

1. **2CH4 (2 cap c cap h sub 4)**:
- This represents two molecules of methanol (CH4), which has 4 hydrogen atoms in each molecule. So, 2CH4 has 2 x 4 = 8 hydrogen atoms.

2. **2H2O (2 cap h sub 2 cap o)**:
- This represents two molecules of water (H2O), which has 2 hydrogen atoms in each molecule. So, 2H2O has 2 x 2 = 4 hydrogen atoms.

3. **HO2 (cap h cap o sub 2)**:
- This molecule has one hydrogen atom (H) and two oxygen atoms (O). So, it has 1 hydrogen atom.

4. **H2SO4**:
- This molecule (sulfuric acid) has two hydrogen atoms (H2) along with sulfur (S) and four oxygen atoms (O4). So, it has 2 hydrogen atoms.

Based on the analysis, the molecule that shows exactly **two atoms** of hydrogen is **H2SO4**.
