17 Αυγ 2024 · In theory, it's easy to make water from hydrogen gas and oxygen gas. Mix the two gases together, add a spark or sufficient heat to provide the activation energy to start the reaction, and presto—instant water.
7 Απρ 2022 · Theoretically, it is possible. You would need to combine two moles of hydrogen gas and one mole of oxygen gas to turn them into water. However, you need activation energy to join them together and start the reaction.
16 Ιουν 2020 · Making water from hydrogen and oxygen is as simple as mixing hydrogen gas and oxygen gas and adding a spark or heat. The balanced equation for the chemical reaction is: 2 H 2 + O 2 → 2 H 2 O. This is a synthesis reaction that makes water from its elements. It’s also a combustion reaction.
13 Ιουλ 2014 · The reverse reaction, water to hydrogen and oxygen, has a positive Gibbs free energy, so you need to add energy in the form of electricity to the system to make the reaction happen.
24 Απρ 2017 · While water can be formed through countless chemical reactions, the most efficient way to create a water molecule out of oxygen and hydrogen atoms is to burn hydrogen gas (H2) in the presence of oxygen gas (O2).
One way to create water is through chemical reactions. Specifically, combining hydrogen gas (H2) and oxygen gas (O2) in the right conditions will result in the formation of water vapor (H2O). This process is called combustion or burning and typically occurs in engines, such as car engines or rocket engines.
Grant Mason from the BYU Department of Physics and Astronomy demonstrates the reaction of hydrogen and oxygen to form water.
