What else can I help you with?
Does hydrogen burn and produce energy when it reacts with oxygen?
Yes, hydrogen burns and produces energy when it reacts with oxygen, a process known as combustion.
Which element is required for the combustion of fossil fuels?
Oxygen is required for the combustion of fossil fuels. During combustion, the carbon and hydrogen in the fossil fuels react with oxygen to produce carbon dioxide, water, and heat energy.
How does the reaction of hydrogen and oxygen to produce energy in a fuel cell differ from their interaction during the direct combustion of hydrogen and oxygen?
In a fuel cell, the reaction of hydrogen and oxygen occurs electrochemically, producing electricity as a byproduct. This process is more efficient and produces less waste compared to direct combustion of hydrogen and oxygen, which releases energy in the form of heat without generating electricity. Fuel cells offer a cleaner and more controlled way to harness energy from hydrogen compared to combustion.
Is energy in water from hydrogen molecules?
No. The hydrogen and oxygen in water are combined into a single substance; it does not get one property from hydrogen or another from oxygen but rather has its own unique set of properties based on how they are combined. It is unclear what "energy" you are referring to.
Why doesn't water formed by hydrogen and oxygen combust?
When hydrogen and oxygen react to form water, the chemical reaction is exothermic, meaning it releases energy in the form of heat. This process stabilizes the water molecules and prevents them from further reacting with oxygen in a combustion reaction. In other words, the energy released during the formation of water is higher than what would be required for further combustion.

Can hydrogen support combustion?
Hydrogen is a fuel for combustion, but cannot support it in the manner than oxygen can.
How is energy released within biomass fuels?
Energy is released from biomass fuels through the process of combustion, where the fuel is burned in the presence of oxygen. During combustion, the carbon and hydrogen in the biomass react with oxygen to release heat energy in the form of heat and light. This energy can be harnessed to produce heat, electricity, or other forms of energy.
How do motors on hydrogen cars differ from combustion or hybrid engines?
Like a gas combustion engine, a hydrogen engine relies on the combustion process - in this case, combustion that results when hydrogen is combined with oxygen. Fuel cells in a hydrogen-powered car then convert this mechanical energy into electrical energy.

Will the energy produced on combustion of hydrogen be more than the energy used for separation of hydrogen from water through electrolysis?
In theory, the energy produced by creating four oxygen-hydrogen bonds after breaking two Oxygen-oxygen and hydrogen-hydrogen bonds in the reaction O2 + 2H2 -> 2H2O (hydrogen combustion in oxygen) is exactly the same than the energy needed to break four oxygen-hydrogen bonds to create two oxygen-oxygen and hydrogen-hydrogen bonds in the reaction 2H2O -> O2 + 2H2 (water electrolysis) However, you will always have great energy loss during electrolysis (an important part of your energy will be used to warm up your water) and in getting back your energy from your oxygen and hydrogen gas (a combustible battery or a motor will warm up too).
Why does hydrogen lose its combustibility after it combines with oxygen?
When hydrogen combines with oxygen to form water, the chemical reaction releases energy and forms a stable compound. This new molecular structure of water does not have the same properties as hydrogen gas, such as combustibility. The energy released during the reaction is no longer available to sustain combustion.
How do we turn hydrogen into energy we can use?
Hydrogen can be burnt with oxygen and the formation of the chemical bonds between the atoms releases energy as heat. Free hydrogen is normally manufactured by electrolysis from water, and this requires energy to separate the hydrogen-oxygen bonds, and it is this energy that is released when the chemical bonds are re-formed by combustion.
Is the Combustion of Hydrogen Endothermic?
No, the combustion of hydrogen is exothermic, meaning it releases heat energy. When hydrogen reacts with oxygen to form water, it releases energy in the form of heat and light.
