    Usually, biomass refers to wood and other plant material. Technically, any organic matter can be burnt as fuel, though, if dry enough.

    Usually charcoal. Coal contains too many impurities such as sulphur, which can make the food you cook on the barbeque toxic because of the gases in the smoke.

    No, we use graphite.

    Lots of artists use charcoal pencils; they certainly work. Charcoal is a darker black colour, whereas graphite is a metallic grey colour. Although both are almost 100% carbon, graphite has a specific arrangement of carbon atoms so that each atom is bonded to 3 others, leaving the other outer shell electrons to be de-localised, making it an electrical conducter. Because of the structure, graphite forms layers, which stack together. Charcoal has a much more random structure, likely tangled chains of carbons rather than a regular structure.

    Yes. Lead is a metal. Have you reviewed the wiki article on what is a metal so you can better understand what that means?
