Question

write the correct formula for each species: sulfur dioxide, sulfur trioxide, the sulfate ion. express your answers as chemical formulas separated by a comma.

Explanation:

Step1: Determine formula for sulfur dioxide

Sulfur dioxide has 1 sulfur (S) and 2 oxygen (O) atoms. So formula is $SO_2$.

Step2: Determine formula for sulfur trioxide

Sulfur trioxide has 1 sulfur (S) and 3 oxygen (O) atoms. So formula is $SO_3$.

Step3: Determine formula for sulfate ion

Sulfate ion is a polyatomic ion with formula $SO_4^{2 - }$.

Answer:

$SO_2$, $SO_3$, $SO_4^{2-}$
