The Methane Bomb !How to you mix oxygen and methaneto make an
EXPLOSION?Balance the following equation:___CH4 + ______O2 === ____
CO2 + ____H2OAvagadros Law: Equal volume of two gases at the same
temperature and pressure contain EQUAL numbers of molecules.
How should the volume of Oxygen gas compare withthe volume of
Methane so neither gas is left over?
MethaneMethane andAir 50-50Methane and Oxygen 1:2
Which one is pure methane?
Lighting the bag of pure methane at the top of the bag.Click for
next pageDouble click on movie to start.(movies must be inserted
into your pptMethane is lighter than airit only burns at the edges
of the ball of rising methane takinga longer time to burn and burns
yellow indicatingincomplete combustion.
Methane and airnotice the change in color and speed of
burn.Double click movie to start.Click here for next pageIncomplete
combustion inside the bag needingoxygen from the air to complete
burning.faster than the lst example.
CH 4 + 2 O 2 == 2 H 2 O + CO 21volume methane to 2 volumes
oxygenDouble click on movie to start.Twice the volume contains
twice the number of molecules of oxygen as methane so complete
combustion can occur within the bag and is much faster!
The explosion is quite loudstudents should be at least10 feet
away.also there is possibility of hot plasticif too close. Dont
expect to do it just once! The expense of having a large bottle
andregulator of oxygen is well worth its use during the year.
