    I don't have too much faith in myself for this one xD. I can tell you this isn't a physical change (changing shape or form.) so exclude 3 and 4. So now they are out of the way, it's either 1 or two.

    As far as I know, the answer is 2. A yellow gas forms.

    But I cannot guarantee it's %100.
