Question

multiple choice 1 point
in which of these compounds are there twice as many oxygen atoms as hydrogen atoms?
h₂so₄
h₃po₄
hclo₃
h₂o

Explanation:

Step1: Analyze $H_2SO_4$

In $H_2SO_4$, there are 2 hydrogen atoms and 4 oxygen atoms. Since $4 = 2\times2$, the number of oxygen atoms is twice the number of hydrogen atoms.

Step2: Analyze $H_3PO_4$

In $H_3PO_4$, there are 3 hydrogen atoms and 4 oxygen atoms. And $4
eq2\times3$.

Step3: Analyze $HClO_3$

In $HClO_3$, there is 1 hydrogen atom and 3 oxygen atoms. And $3
eq2\times1$.

Step4: Analyze $H_2O$

In $H_2O$, there are 2 hydrogen atoms and 1 oxygen atom. And $1
eq2\times2$.

Answer:

$H_2SO_4$
