Question 1

graphite has a ____ melting and boiling point?

Answer 1

graphite has a high melting and boiling point

Question 2

why does graphite have high melting and boiling points?

Answer 2

because a lot of energy is needed to break the large amount of strong covalent bonds

Question 3

why is graphite a good conductor of electricity and heat?

Answer 3

because every carbon atoms bonds forms 3 bonds, leaving one delocalised electron free to move about and conduct electricity and thermal energy

Question 4

Answer 5

hexagonal rings are arranged into layers, with no covalent bonds in between layers

Question 6

because there is no covalent bonds between layers, this means that layers can slide over, making graphite ___ and ___?
