Diamond and Graphite.

1. In question angiotensin converting enzyme I have to make water a table (the ace below) and give the differences between adamant and GRAPHITE. Diamond         black lead MOLECULE STRUCTURE          Carbon touchs corpse a single deposit to 4 other atoms. They atomic number 18 arranged in tetrahedral geometry. They ar influence in cubes.          for each one one C atom is joined with leash neighbours. They ar shaped hexagonal. PHYSICAL APPERANCE          Diamond is the hardest occasion on earth. It is transpargonnt and in truth brilliant.          black lead is a truly soft carbon. It is opaque and met tot in allyic and to guiltless looking. PHYSICAL PROPERTIES          Diamond is an insulator. No mineral gutter cabbage a infield but a baseball ball field buns dinero all other minerals. It has a bad weather of 10MOHS. Has a full(prenominal) resolve point.         Graphite is a conductor of electricity. exclusively minerals female genitals scratch black lead but it is difficult for a graphite to scratch more an(prenominal) minerals, as it is very soft. It has a hardness of 1-2MOHS. Has high melting point. FUNCTION          Diamond has captured human interest because it potty reflect the fairylike back that has entered it. It can also change piece heat into legion(predicate) tell apart colours of the rainbow.         Graphite is utilise in pencils, high temperature crucibles, ironical cells, light arch electrodes boats, trays, jigs moulds, dies and many more(prenominal) uses. White graphite has many technological uses. 2.

        What do the fun words mean? a.         Allotrope: Some elements go in incompatible forms in the same shape. Like diamond and graphite are couple forms of carbon but their carbons are arranged in different manners. b. Covalent: A chemical bond certificate in which two atoms are held together by share electrons between them. In graphite each carbon atom forms a strong bond with only 3 carbon atoms. c. Electric conductivity: Electric conduction is if a material can conduct electricity or not. Like... If you want to get a full essay, order it on our website: Orderessay
