Question

What is the difference between `SO_2`, and `SeO_2`?

Answer 1

`SO_2` is a room temperature gas that has a normal boiling point of `-10` `""^@C`.

Explanation:

And as I recall `SeO_2` is a non-molecular, room temperature solid. On the other hand, `SO_2` is molecular.

`SeO_2` is comprised of one selenium atom, and two oxygen atoms, while `SO_2` is made up of one sulfur atom and two oxygen atoms. In `SeO_2` there are no molecular boundaries.

And `SO_2` is a room temperature gas....that has a boiling point of `−10^∘C`

And so we truly compare apples with oranges.........
