When hydrogen peroxide is added to yeast, an exothermic reaction occurs, which means the temperature rises. To combine hydrogen and oxygen to make water, you basically have to mix the gases together and light them with a match. How can I trap the hydrogen and oxygen for later use?

The way of mixing (sludge or biogas recirculation) and the point of oxygen supply (headspace or liquid phase) played an important role on hydrogen sulphide oxidation.
I plan on getting the hydrogen and oxygen through the electrolysis of water. It said to mix the gases together and light them with a match. Hydrogen peroxide is a powerful oxidising agent but is unusual in that it can act as reducing agent under certain conditions. The intensive mixing characteristics of these innovative burners have been developed through extensive test work at Linde’s own pilot plant – Experiments simulating mixing of liquid oxygen (LO(2)) and liquid hydrogen (LH(2) have been performed. If you mix hydrogen and oxygen then set the mixture on fire, you'll get water.
No : mixing both gasses in one reservoir/container under low pressure and even in the right stoichiometric mix will not result in water being formed. This is because the speed of the molecules does not provide enough kinetic energy to activate the reaction during collisions between the reactants.

A mixture of gases is formed, with the potential to violently react if sufficient energy were introduced to the mixture. The reaction might look like this ... 2H2(g) + O2(g) --> 2H2O They measured the pressure developed in various gas mixtures, the greatest pressure of 7.6 atm being developed for a stoichiometric mixture of hydrogen and oxygen. For a science fair, I am planning on combining hydrogen and oxygen to form water. During combustion, oxygen is added to a molecule, which produces water in this reaction. Hydrogen and oxygen gases mix at room temperature with no chemical reaction. Abstract: Hydrogen peroxide is a substance which destroys yeast, an organic fungi. Just the mixing of hydrogen and oxygen isn't a change at all. The ratio is 2 parts hydrogen atoms to one part oxygen atoms--or really one H2 molecule plus one oxygen … (Something Cheap) I read in one website how to make water with hydrogen and oxygen. Reacting hydrogen and oxygen is basically burning hydrogen gas, except rather than using the limited amount of oxygen in the air, you're feeding the fire. No & Yes, No : Mixing a few steel gas cylinders won’t give any result exept a lot of noise. Yeast has an enzyme has catalase which acts as a catalyst.
