What kind of energy is used when water decomposes?
To separate water into hydrogen and oxygen, electrolysis is usually used; this uses electrical energy. Of course, the electrical energy can be generated in any of several ways.
What kind of electricity supply is used for electrolysis?
It must be direct current for electrolysis.
Why is it important to recycle the metals you extract using electrolysis?
It takes a lot of electric power to refine metals by electrolysis. Such metals therefore are a kind of stored energy. If they are not recycled, that energy is lost.
What are the products when water is broken down by electrolysis?
The two products when water is broken down by electrolysis is hydrogen gas and oxygen gas. The energy source in photosynthesis is light energy.
Why is it important to recycle metals that you extract by electrolysis?
It takes a lot of electric power to refine metals by electrolysis. Such metals therefore are a kind of stored energy. If they are not recycled, that energy is lost, and more energy will be needed to refine more metals by electrolysis to replace them. High energy consumption is a major factor in environmental pollution.
In what compuonds is oxygen found and how is it extracted?
Oxygen can be found in H20 (water). It can be separated through electrolysis The equation for the electrolysis of water is 2[H20]+energy = 2[H2] + 02
How can water be used as electrical energy?
There is no useable electrical energy in water. But if by electrolysis the water can be split into separate hydrogen and oxygen components which are collected separately, the hydrogen can be burnt as a fuel. When the hydrogen is burnt, no more energy is produced than what went into the original electrolysis, so the water is not a source of energy, it is more of a way to store energy. Moving water can be used to generate electricity, in hydroelectric schemes and in tidal and wave generators.
Is it possible to produce hydrogen and oxygen from electrolysis of water and then burn both of them in internal combustion engine to drive an automobile and Is this hydrogen and oxygen is enough for?
It would be possible but not practical. The electrolysis of water requires energy. Just as much energy goes into the water that is electrolyzed as comes out from burning the hydrogen and oxygen. However, not all of the energy would go into splitting the water during electrolysis and you cannot recover all of the energy from burning it, so neither process is 100% efficient. It would be more efficient to have the electricity power the car directly.
Which energy converts to which energy in electrolysis?
In electrolysis Electrical energy is used for changing thestate of Chemical / Metal structure. Usually during this process heat energy is released as by product.
What happens to lost energy when water is created?
It forms covalent bonds between hydrogen and oxygen. The energy is released when the bonds are broken through electrolysis.
What is the energy source that splits water?
Water can be split into hydrogen and oxygen either:Thermally (water thermo-chemical decomposition) using high grade thermal energy (at temperature preferably above 1000 Co ), orElectrically (water electrolysis) using electrical energy.
How can water be decomposed into its elements hydrogen and oxygen?
Electrolysis of water using carbon rods and a low voltage of electric current will break down water into hydrogen and oxygen. Theoretically, thermolysis (electrolysis at a high temperature) would be more efficient, given a suitable source of heat energy.
