Hi! I am having some trouble with this question, can you please help me?
Which of the following describe chemical properties? Check all that apply.
- Iodine (a purple solid) becomes a purple gas.
- Titanium is less dense that iron .
- Water freezes at 0'C
- Sugar burns in air to form water and carbon dioxide.
I am thinking that the answer is only the last option, sugar burns in air to form water and carbon dioxide. But I am not sure.
Thanks for your help.

The last one is the only one that involves a chemical reaction.
