We had one of Najwa’s friend over and decided to do a science experiment. The goal was to electrolyze water so that it decomposes into two gases: oxygen O2 and hydrogen H2. The end results is that there’s twice as much hydrogen as oxygen creating what’s called oxyhydrogen. And when this is placed near a flame, the gas ignites.
The chemical formula of a water molecule is H2O, which means that it consists of two hydrogen atoms and one oxygen atom. The bottle contains a mixture of two parts gaseous hydrogen and one part gaseous oxygen. When this mixture is ignited, the immediate reaction of water formation takes place with a characteristic “pop!” sound. The water vapor formed in this reaction blows the candle out.
