Hydrogen peroxide heat of reaction
WebPlace about 1 cm 3 of washing up liquid into each of the measuring cylinders. To each one add the amount of catalyst specified above. Then add 25 cm 3 of 50 volume hydrogen peroxide solution to each cylinder. The addition of the catalyst to each cylinder should be done as nearly simultaneously as possible – using two assistants will help. WebHydrogen peroxide's chemical formula is H 2 O 2. When it comes into contact with silver, the silver acts as a catalyst. The reaction frees the extra oxygen atom to produce water, and also generates a lot of heat. The heat turns the water into steam, which the engine can eject at a very high speed through a rocket nozzle.
