When you burn a mixture of iron and sulphur, iron sulpide is made. What is the gas given off?
^Please help me!!!
If it is just a reaction of Fe and S, no gas is given off.
HOWEVER, when igniting this in air, the stuff is so hot, iron sulfide fumes come up, sulfur comes up, and some sulfur dioxide comes up from the hot reaction going on in air. The sulfur dioxide will bring tears to your eyes.
