- An experiment to prove that 21% of
the air is oxygen
- At the start 100cm cubed of air contained
- 78cm cubed nitrogen
- 21cm cubed oxygen
- 1cm cubed argon
- At the end only 8cm cubed of air remained
- 78cm cubed N2
- 1cm cubed Ar
- All oxygen was used in the reaction
- 78cm cubed N2
- 78cm cubed nitrogen
- Reaction:
- copper+oxygen
