To determine which of the given molecules shows two atoms of hydrogen (H), let's analyze each option:
A. H2SO4 (Sulfuric acid): This molecule contains 2 hydrogen atoms (H2).
B. HO2 (Hydrogen peroxide): This molecule contains 1 hydrogen atom (H) and 2 oxygen atoms (O2).
C. 2H2O (Water): This notation means there are 2 molecules of water, each containing 2 hydrogen atoms. Therefore, 2 H2O contains a total of 4 hydrogen atoms (2 x 2 H = 4 H).
D. 2CH4 (Methane): This notation means there are 2 molecules of methane, each containing 4 hydrogen atoms. Therefore, 2 CH4 contains a total of 8 hydrogen atoms (2 x 4 H = 8 H).
The correct answer is **A. H2SO4**, as it contains exactly two atoms of hydrogen.
