A

Oxidising
reactive with combustible subsatnces to cause fire
fumes in moist air
soluble in water and forms Hydrochloric acid
A mixture of Chlorine and Hydrogen explodes when exposed to sunlight to give Hydrogen Chloride. In the dark, no reaction occurs, so activation of the reaction by light energy is required.
Chlorine combines directly with most non-metals
