Question

which of the following molecules shows two atoms of hydrogen (h)? (1 point) o h₂so₄ o ho₂ o 2ch₄ o 2h₂o

Explanation:

Step1: Analyze $H_2SO_4$

In $H_2SO_4$, the sub - script 2 next to $H$ indicates there are 2 hydrogen atoms in one molecule of sulfuric acid.

Step2: Analyze $HO_2$

In $HO_2$, there is 1 hydrogen atom in one molecule.

Step3: Analyze $2CH_4$

In $CH_4$, there are 4 hydrogen atoms in one molecule of methane. And the coefficient 2 just means 2 molecules of methane, so the total number of hydrogen atoms in $2CH_4$ is 8.

Step4: Analyze $2H_2O$

In $H_2O$, there are 2 hydrogen atoms in one molecule of water. But the coefficient 2 means 2 molecules of water, so the total number of hydrogen atoms in $2H_2O$ is 4.

Answer:

$H_2SO_4$
