Na2S + HNO3 à2NaNO3 + H2S
Hydrogenation: Fullerenes are easily hydrogenated by several methods to C60H18, C60H36.
Bromination: Bucky ball can added up 24 bromine atoms to the sphere C60Br24. Fluorine can also be added up C60F48.
Friedel-Craft Alkylation: Buck ball ann react with carbo-benzene and aluminum chloride in a fiedel-craft alkylation type reaction.

(2n+1)H2 + nCO à CnH2n+2 + nH2O
Cyclic Compound: Ring or closed chain compounds in which carbon is attached with each other in the form of ring. General formula is CnH2n. They have two less hydrogen atoms than open chain compounds. Melting point, boiling point and densities are more due to more compact structures. Example cyclo-prpane, cyclo-butane.
Coal: coal is a solid black or brownish black sedimentary rock usually found in layers called coal beds, coal is the major source of energy all over the world.
