- T 1: earths early atmosphere
- 1)volcanoes caused the early atmosphere and released number of gasses
- 2) the gasses released was little oxygen, little argon, water vapor, carbon dioxide, nitrogen
- when the earth has cooled down water vapor condensed and formed into to oceans and seas
- then once oceans formed green plants evolved and photosynthesis's and produced oxygen. ( that how oxygen increased in the early atmosphere)
- dead organism raised once oxygen was present and absorbed co2 in the atmospherethis is also know as ( calcium carbonate
- then once oceans formed green plants evolved and photosynthesis's and produced oxygen. ( that how oxygen increased in the early atmosphere)
- when the earth has cooled down water vapor condensed and formed into to oceans and seas
- 2) the gasses released was little oxygen, little argon, water vapor, carbon dioxide, nitrogen
- 1)volcanoes caused the early atmosphere and released number of gasses
- T 2: types of rocks formed
- sedimentary rocks formed: when dead marine organism sunk to the bottom of the sea, as layers and layers over pile high pressure caused it to squash ans formed sedimentary rock.
- T 3: acid & alkali & indadigestion
- acids: PH 1-6 alkali PH 8-14
- ACID + BASE ( GREATER THAN PH 7) = SALT + WATER
- 3 ACIDS: hydrochloric acid (hcl) nitric acid and sulfuric acid
- e.g. hcl + metal hydroxide = salt ( sodium chloride) + water (H2O)
- acid + alkali = nutralisation
- indigestion tablets: ! it convert excess acid in the stomach into water (H2O)
- acid + alkali = nutralisation
- e.g. hcl + metal hydroxide = salt ( sodium chloride) + water (H2O)
- 3 ACIDS: hydrochloric acid (hcl) nitric acid and sulfuric acid
- ACID + BASE ( GREATER THAN PH 7) = SALT + WATER
- acids: PH 1-6 alkali PH 8-14
- T 4: metal ores & electorlysis
- metal ores are when metal can be extracted from oxygen. oxidase means gaining oxygen. reduction is losing oxygen
- you can extract metal also by electrolysis meaning using water and electricity to separate two compounds
- REMEMBER! POTASSIUM,SODIUM, CALCIUM,MAGNISIUM AND ALUMINIUM ARE MOST REACTIVE AND USED TO ELECTROLYSIS
- remember!c zinc, iron, lead, tin, copper are least reactive so they are extracted by carbon!
- REMEMBER! SILVER GOLD AND PLATINUM ARE UNCOMBINED METALS
- ELECTROLYSIS IS USED BY D.C CURRENT AND BREAKS THE TWO ATOMS OF THE COMPOUND APART!
- REMEMBER! SILVER GOLD AND PLATINUM ARE UNCOMBINED METALS
- remember!c zinc, iron, lead, tin, copper are least reactive so they are extracted by carbon!

- T 5: combustion & recycling & pollution
- CRUDE oil: is a mixture of hydrocarbons and is fossil flues that is burned into fractional distalation
- it is fraction-ed into: bitumen+fuel oil+kerosene+deasil+naphtha+petrol+gasses
- complete combustion is when there is plenty of oxygen and we can know this because it produce a clear blue flame
- incomplete combustion is when there in not enough oxygen to go round we can know this when the flame is orange and this means that its giving off carbon monoxide which is a toxic gas as it can kill humans
- this cause global warming and acid rain because co2 and sulfur causes acid rain which kills trees and limestone building
- recycling is a way to cause less pollution also its re- usable and we are not wasting earth natural resources also it can take up landfill sites and take energy and sort them into to metals, wood and plastics
- this cause global warming and acid rain because co2 and sulfur causes acid rain which kills trees and limestone building
