All combustion reactions involve a chemical change in which oxygen reacts with elements or compounds to produce oxides. Combustion reactions give out heat, so they will always be exothermic reactions. You need to be able to describe the combustion reactions of magnesium, hydrogen and sulfur.
A variety of fuels undergo combustion, and the products made can be identified. The fire triangle identifies the three things that are required for a fire to burn. Calorimetry is used to measure...
Adjust the flow of hydrogen so that a test tube can easily be filled to a given mark. Allow the gas to escape for a minute or two to purge all the air from the system. If the hydrogen contains little or no air, then a test tube full should ignite without a ‘pop’ and burn quietly.
