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. so₂, so₃, so₄²⁻ previous answers correct part b list as many similarities between these three species as you can. check all that apply. ☐ all contain 1 sulfur atom. ☐ all represent cations. ☑ all contain nonmetals only. ☑ all have a charge. ☐ all contain sulfur and oxygen. ☑ all represent anions. submit previous answers request answer incorrect; try again; one attempt remaining

Explanation:

1. Analyze each option:

• "All contain 1 sulfur atom": $SO_2$, $SO_3$, and $SO_4^{2 - }$ each have 1 S atom. This is correct.
• "All represent cations": $SO_2$ and $SO_3$ are neutral molecules, $SO_4^{2 - }$ is an anion. So this is wrong.
• "All contain nonmetals only": S and O are nonmetals. This is correct.
• "All have a charge": $SO_2$ and $SO_3$ are neutral (charge = 0), $SO_4^{2 - }$ has a charge. So this is wrong.
• "All contain sulfur and oxygen": $SO_2$ (S, O), $SO_3$ (S, O), $SO_4^{2 - }$ (S, O). This is correct.
• "All represent anions": $SO_2$ and $SO_3$ are neutral molecules, not anions. So this is wrong.

1. Correct options: "All contain 1 sulfur atom", "All contain nonmetals only", "All contain sulfur and oxygen".

Answer:

• All contain 1 sulfur atom.
• All contain nonmetals only.
• All contain sulfur and oxygen.
