Carbon Flashcards
Bonding and structure in graphite
Covalent giant lattice
Each carbon atom is covalently bonded to 3 other carbon atoms, forming layers of hexagons which easily slide over each other
Bonding and structure of buckminsterfullerene
Covalent simple molecular
Strong covalent bonds within the molecules but weak intermolecular forces between the molecules
Acid + metal carbonate =
Salt + Carbon dioxide + water
Metal carbonate =
Metal oxide + carbon dioxide
Key phrase about carbon monoxide
It is a colourless, odourless and extremely poisonous gas because it reduces the capacity of the blood to carry oxygen
Why is carbon dioxide used in fizzy drinks
It is slightly soluble in water
What happens when carbon dioxide reacts with water
It undergoes a chemical reaction with the water to form a weak acid, carbonic acid (H2CO3)
Why is carbon dioxide used in fire extinguishers
It is more dense than air and does not support combustion
Bonding and structure in a diamond
Covalent giant lattice
Each carbon atom is covalently bonded to 4 other carbon atoms
