Method 1. Set up the experiment as shown in the diagram.
Glass funnel Glass tubing into the atmosphere.
Vacuum pump
Twin-holed stopper
Limewater
2. Switch on the vacuum pump. 3. Light the Bunsen burner to burn methane gas. 4. Leave fuel to burn. 5. Record your results and account for any changes you see in the test tube containing limewater.
Analyse and interpret 1. What gas is produced when methane is burned? 2. What does this experiment tell you about the effect that burning fossil fuels has on CO2
levels in the atmosphere? 3. What is the chemical equation for the combustion of methane gas?
