The combustion reaction of hydrogen and oxygen produces the explosive energy needed to power the space shuttle and is being engineered as a source of continuous energy for fuel cells in electric vehicles. With the Micro Mole Rockets: Hydrogen and Oxygen Mole Ratio—ChemTopic™ Lab Activity, generate microscale quantities of hydrogen and oxygen and test their explosive nature separately and in proportional mixtures to find the most “powerful” gas mixture that can launch a rocket across the room!
