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.
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?
It is much easier to control the hydrogen and oxygen during direct combustion than during their reaction in a fuel cell.
Does oxygen produce energy under combustion?
Oxygen can react with other elements and release energy.
What two type of bonds do water molecules form?
Hydrogen and oxygen are the component of elements of water, which give water the chemical formula H2O. There's plenty of oxygen in our air; about 20% of our air is oxygen. Hydrogen, however, isn't so common. It's so light that it rises straight up into the upper atmosphere and often just keeps going right into space.
What are the essential elements in order that combustion take place?
there should b presence of oxygen....

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).
What are two indicators that a combustion reaction has occurred?
energy is released and oxygen is consumed
What releases water and energy?
Combustion of hydrogen gives a lot of heat and water. The stoichiometric reaction of hydrogen with oxygen is: 2H2(g) + O2(g) gives 2H2O(l) + 572 kJ Hydrogen's Enthalpy of Combustion is 286 kJ/mole
What process can make pure water?
If pure water is required the combustion of hydrogen and oxygen in a previously evacuated inert container would provide the purest result
Does oxygen produce energy under combustion?
Oxygen can react with other elements and release energy.
What is the real principle behind hydrogen fuel cars?
Two hydrogen molecules combine with one oxygen molecule to form two molecules of water. This is the combustion of hydrogen. The end product is water vapor. In the burning process, energy is released much the same way that gasoline burns in a car engine. Same process, different fuels. But in this case, there are no noxious byproducts of combustion - only water.
How is the energy from biomass released?
Energy from biomass is released by combustion.
Why does complete combustion release more energy than incomplete combustion?
in complete combustion the amount of oxygen is higher/more than the amount of oxygen in incomplete combustion. Heat needs oxygen.
Does the sun's energy come from the burning combustion of hydrogen?
No. The sun's energy comes from the nuclear fusion of hydrogen, not combustion. In this reaction hydrogen atoms fuse with one another to form helium atoms. The fusion of hydrogen yields about 4.5 million times more energy than you would get from burning the same amount.
