ChemistryThe earth and its atmosphereGCSEOCR Created by: saradomiCreated on: 13-04-14 13:24 what was the early atmosphere made up of? mostly CO2, water vapour with virtually no oxygen 1 of 10 how did the oceans form? when the water vapour condensed when the earth cooled 2 of 10 how did the early CO2 dissolve? a lot of it dissolved into the oceans, green plants also removed carbon dioxide and produced oxygen by photosynthesis 3 of 10 what is the earths atmosphere made up of today? nitrogen 78% oxygen 21% argon 1% 4 of 10 how is carbon monoxide produced? if there's not enough oxygen available when fuel burns, this is called incomplete burning 5 of 10 in what form does sulfur dioxide leave the atmosphere? acid rain 6 of 10 how is nitrogen monoxide formed? when nitrogen and oxygen in the air are exposed to very high temperatures, this happens in car engines 7 of 10 how is nitrogen dioxide formed? once the nitrogen monoxide is in the air, it goes on to react with more oxygen, producing nitrogen dioxide 8 of 10 what do catalytic converters in cars do to nitrogen monoxide? converts nitrogen monoxide into nitrogen and oxygen, this is a reduction reaction as the nitrogen loses oxygen 9 of 10 what do catalytic converters do to carbon monoxide? converts carbon monoxide into carbon dioxide by adding oxygen, this is an oxidation reaction 10 of 10
