Carbon Dioxide
- even though it takes up less than 1% of the air it has vital importance
- carbon dioxide is produced when carbon is burned in oxygen gas
- the word equation is; calcium carbonate + hydrochloric acid
= calcium chloride + water+ carbon dioxide
- CaCO3 + 2HCL = Cacl2 + h2o +co2
- CaCO3 + 2HCL = Cacl2 + h2o +co2
- the word equation is; calcium carbonate + hydrochloric acid
= calcium chloride + water+ carbon dioxide
- carbon dioxide is produced when carbon is burned in oxygen gas
- you can test for the presence of co2 using limewater
- limewater + carbon dioxide = chalk + water
- Ca(OH)2 + CO2 = CaCO3 +H2O
- Ca(OH)2 + CO2 = CaCO3 +H2O
- limewater + carbon dioxide = chalk + water
