Resource summary

Carbon Dioxide
1 even though it takes up less than 1% of the air it has vital importance
1.1 carbon dioxide is produced when carbon is burned in oxygen gas
1.1.1 the word equation is; calcium carbonate + hydrochloric acid = calcium chloride + water+ carbon dioxide
1.1.1.1 CaCO3 + 2HCL = Cacl2 + h2o +co2
2 you can test for the presence of co2 using limewater
2.1 limewater + carbon dioxide = chalk + water
2.1.1 Ca(OH)2 + CO2 = CaCO3 +H2O
3 physical properties
3.1 colourless, odourless, tasteless gas
3.1.1 slightly soluble in water
3.1.1.1 more dense than air
4 chemical properties
4.1 does not support combustion
4.1.1 turns limewater milky
4.1.1.1 dissolves in water to form carbonic acid
5 uses of carbon dioxide
5.1 fizzy drinks
5.2 fire extinguishers
5.3 refrigeration
