Answer 1

Answer:

1) Petroleum is a naturally occurring complex mixture made up predominantly of organic carbon and hydrogen compounds. It also frequently contains significant amounts of nitrogen, sulfur and oxygen together with smaller quantities of nickel, vanadium and other elements.

2) Liquid and gaseous fuels do not leave any residue after burning. ... Liquid and gaseous fuels produce little or no smoke, whereas most of the solid fuels burn with smoke. 6. Liquid and gaseous fuels have relatively low ignition temperature and hence they burn more easily than solid fuels.
