Answer:
C10H22
Explanation:
Graphite is known as an allotrope of carbon. Its characteristics include being black and slippery and as used as lubricants.
Gold (Au) is an element on the periodic table with atomic number 79 and a mass number 197 which exists as a metal due to its hydrogen bonds.
C10H22 which is also known as decane belongs to the Alkane family.The General forces of attraction between the alkane family are weak but in the case of decade there is Van der waal force which makes Decane C10H22 a Molecular Solid.
