oil

• crude oil is formed from the remains of ancient plankton and marine algae
• alkanes are saturated hydrocarbons with the general formula CnH2n+2
• filtration is used fo seperate an insoluble solid from a liquid
• evaporation is used to separate a soluble solid from a solution
• distillation is used to seperate liquids with different boiling points
• volatility is the tendency to turn into a gas
• viscosity is how easily it flows
• flammability is how easily it burns
• cracking is the thermal decomposition of long chain alkanes into shorter chain alkenes
• the two types of cracking are steam and catalytic cracking
• alkenes are unsaturated hydrocarbons and have a general formula of CnH2n
• a monomer is a small molecule that bonds with other small molecules to form a larger molecule (polymer)
• a polymer is a large, long chain molecule made from many monomers joined together
