What happen when the following substances were ignited?

Question

1.) Hexane
2.) Benzene
3.) Acetylene

Answer 1

These three substances are hydrocarbons.

So when they are burned at an open area,it inflames giving Carbon dioxide and water. As the reaction is exothermic,lot of heat will be produced.

But if they are burned in a closed area with limited oxygen they burn to give carbon monoxide instead of carbon dioxide.Otherwise the reaction would be same with same observations.

So it depends where u inflame them

Answer 2

Acetylene is a gas with a wide explosive range.
It will burn very quickly.

Hexane will be either a light liquid or vapor at normal temp.s /press.
It will burn somewhat more slowly.

Benzene is a heavier liquid, will be more difficult to ignite, will produce the most energy / volume.

Answer 3

they combine with oxygen and get oxidised.

acytelene burns and gives out a lot of heat....used in oxy-acetylene torches.

Answer 4

That stuff is probable the fragrance or physique spray oils that grew to become into used in the cologne plus regardless of alternative factors have been used in the formula, ie. coloring brokers, fixatives, and so forth.
