Aim: to carry out a test for the presence of oxygen
Method
1:light your bunsen burner
2: add the magnese dioxide to boiling tube and place it in your test tube rack
3:add 2ml of hydrogen peroxide
4: light splint and let it burn a while
5: blow the splint out and insert the glowing embers into the mouth of the boiling tube.
Observation when we added the two chemicals together it foamed up, went brown and heated up. when we put the glowing ember it re lit the splint.
Disscusion: the reason it foamed up is because gas got trapped in the liquid causing it to foam up. the reason it relighted the splint is because it is nearly a pure oxygen environment
conclusion: we did not use the bunsen burner we just lit the splint with a lighter but other wise it worked
