Diamond is extremely hard and does not conduct electricity. Which statement explains these properties?.

C. It has no delocalised electrons and each carbon atom forms four covalent bonds with other carbon atoms.

Explanation:

Diamond is composed solely by carbon atoms. As the difference of electronegativity between atoms is 0, diamond is a fully covalent compound.The lack of electrical conductivity stems from a lack of available electrons, this means that there are no delocalised electrons.

The information in the first point discards options A and D, while the second point discards option B. Thus the answer is option C.

Adozen is 12, and your needing to calculate the weight of one medium egg, so i would do 21/12=1.75 per egg, and check your answer by doing 1.75 * 12= 21 : ) : ): ): ): ) i hoped i

The correct answer is weight.
