Concentration, changing temperature, pressure and surface area
Name the four things that increase rate of rection.
A compound of hydrogen and carbon only.
What is a hydrocarbon
Black, viscous and can cause cancer
Describe crude oil
Refinery gas, gasoline, naptha, kerosene, diesel oil, lubricating oil, fuel oil and bitumen
What is the order of the products made from the fractional distillation of crude oil.
Cars
What is gasoline used for?
Making chemicals
What is naptha used for?
Jet fuel
What is kerosene used for?
Large vehicles like trucks
What is diesel used for?
Oils, waxes and polishes
What is lubricating oil used for?
Tarmac and roofing.
What is bitumen used for?
Soulful dioxide and nitrogen dioxide
What two chemicals cause acid rain?
Hydrocarbon + oxygen = carbon dioxide + water
What is the chemical equation for complete combustion?
The carbon oxidises to carbon dioxide and hydrogen oxidises to water
What happens to carbon and hydrogen in complete combustion?
Hydrocarbon + oxygen = carbon monoxide + water
What is the chemical equation for incomplete combustion?
When there is an insufficient supply of oxygen
When does incomplete combustion occur?
Carbon monoxide gets into the blood stream and stops red blood cells from carrying oxgen, tissues and cells die.
Why is carbon monoxide poisonous?
Lime water will go from clear to cloudy.
What is the test for CO2
Put a lit splint in a test tube of hydrogen
What is the test for hydrogen
Anhydrous copper sulphate turns from white to blue.
What is the test for water
Because it is a mixture of hydrocarbons which are not chemically combined.
Why is crude oil a mixture
Nitrogen, carbon dioxide, water, carbon monoxide, nitrogen monoxide, carbon particulates (soot)
What comes out of the exhaust of a car?
A mixture of hydrocarbons
What is fuel
A unit molecule from which a polymer is made
What is a monomer
A long chain molecule made up of repeating units of monomers
What is a polymer
A monomer which is put in brackets to show what would be repeated
What is a repeating unit
A bond that connects two atoms
What is a double bond
By burning in incinerators or burying
How are polymers usually disposed of
Plastic bags and bottles
What is polythene used for?
Crates and ropes
What is polypropene used for?
Water pipes and cable insulation
What is polychlorothene used for?
Because they have very strong bonds
Why are polymers difficult to break down?
