Combustion+II

__ COMBUSTION Station one: __ Combustion 2 : This is a process in which a substance reacts with oxygen to give heat an light. __ Equations of combustion: __ One example: C3H8 + 5 O2 ® 3 CO2 + 4 H2+ heat + light = Propane gas Another example: CaCO3 ® CaO + CO2 + heat+ light= calcium carbonate Websites: [] []

Station 2 The two real life examples are shown below Wood- is an example of combustion, the process of combustion in burning wood is that the wood heats up to approximately 212 Fahrenheit then it evaporates the moisture in it, at this point no heat is coming from the wood. The wood solids start to break down, which converts the fuel gases which in turn release fuel vapors. The second example is Combustion of a rocket engine ,the process is that oxygen is presented and it resolve in heat ,which produces hot gas from the pre burner which is used to power the engine pumps. The left over gas is then injected in the combustion chamber, which in side is high pressure which ,in turn makes the rocket go. [] [] [])

Station 3

station 4 media type="custom" key="3675303" __ Station 5 __ Methane + oxygen  à    carbon dioxide + water + heat + light CH4 + 2O2   à    CO2 + 2H2O + heat + light Combustion- burning of a fuel in the presence of oxygen. Requirements: fuel, oxygen, ignition source. fuel= hydrocarbon or alkanes In this reaction we had a sealed methane gas filled easter egg with a hole in the top covered by a piece of tape. We struck a match( ignition source) and removed the tape releasing the gas. Oxygen is present which leads to the final little poof when they combine.
