Combustion is basically the process of burning something. For combustion to take place there must be three key components: A fuel, an oxidizer and something to ignite the fuel. The ignition will light the fuel then the oxidizer feeds the burning fuel oxygen which makes the fire bigger. Fuels can be in many different forms they can be in the form of solids, liquids or gas. Something we did during class to get a better understanding was we created hydrogen by using magnesium and citric acid and it filled up a balloon then we burned it. Personally I'm a hands on learner so this was great for me. When we burned our balloons I believe that the candle ignited our hydrogen and then since it was a gas all the oxygen around it oxidized it and created an explosion (Look at the image below) Update: On tuesday we actually went into great detail on what exactly happened on an atomic level. When we mixed magnesium with the citric acid we created hydrogen. When we added heat to the whole equation all the atoms started to move around and that released energy which is what we saw as an explosion.
