which of the following molecules shows two atoms of hydrogen (h)? (1 point)\n○ h₂so₄\n○ ho₂\n○ 2ch₄\n○ 2h₂o
Answer
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. But the coefficient 2 in front just means 2 molecules of $CH_4$, so the number of hydrogen atoms in 2 molecules is $2\times4 = 8$.
Step4: Analyze $2H_2O$
In $H_2O$, there are 2 hydrogen atoms in one molecule. The coefficient 2 in front means 2 molecules of water, so the total number of hydrogen atoms is $2\times2=4$.
Answer:
$H_2SO_4$
