chemical reactions quick check\nwhich of the following molecules shows two atoms of hydrogen (h)? (1 point)\n○ 2ch₄\n○ h₂so₄\n○ ho₂\n○ 2h₂o
Answer
Explanation:
Step1: Analyze $2CH_4$
The sub - script of $H$ in $CH_4$ is 4, and with the coefficient 2, the number of $H$ atoms is $2\times4 = 8$.
Step2: Analyze $H_2SO_4$
The sub - script of $H$ is 2, so it has 2 hydrogen atoms.
Step3: Analyze $HO_2$
The sub - script of $H$ is 1, so it has 1 hydrogen atom.
Step4: Analyze $2H_2O$
The sub - script of $H$ in $H_2O$ is 2, and with the coefficient 2, the number of $H$ atoms is $2\times2=4$.
Answer:
$H_2SO_4$
