Couple of questions to those knowledgeable and been researching Chemtrails

Aeroplanes run on Jet fuel.

Jet fuel is ignited and burned in the jet engines.

Jet fuel is made from crude oil. Crude oil comes out the ground and is refined in an oil refinery. Crude oil is refined & spilt up and made into various oils….for example gasoil, gasoline, kerosene, naphtha, lube oil etc….its a long list of different oils that mankind can use that come from crude oil. I know mercury is in crude oil, depending from which hole it comes out of….maybe the mercury is not refined out in the oil refinery?

Q: Does anyone know what the chemical make-up of Jet fuel is? Jet fuel is made up of various chemical components….is one of those components mercury?

Q: What happens to mercury when it is burnt/ignited? Is it turned into something else? Is it destroyed? Does it turn into a gas? Is the gas heavier or lighter than air? Or does it remain as liquid mercury and fall to the ground? That smoking tooth video…the mercury vapour rises up.
