Petroleum is essentially highly reduced (i.e. opposite of oxidized) carbon in liquid form. This means molecules about 4 or 5 carbons up to maybe 25 carbons, bonded with (mostly) hydrogen. read more
Petroleum is essentially highly reduced (i.e. opposite of oxidized) carbon in liquid form. This means molecules about 4 or 5 carbons up to maybe 25 carbons, bonded with (mostly) hydrogen. The reason it is so useful is that you can react it with oxygen (air) and burn it for energy. read more
