How much does a hydrogen fuel cell cost?
There are currently no hydrogen powered cars commercially available. These cars would be far from green in any event because of the way we make hydrogen currently. Hydrogen is currently made by stripping hydrogen from natural gas and venting the rest of the material to the air.
How much energy is released when hydrogen and oxygen gases react to produce 15.0gg of water?
When hydrogen and oxygen gases react to produce water, 285.5 kJ of energy is released per mole of water formed. To calculate the energy released when 15.0g of water is produced, you first need to determine the number of moles of water produced, then multiply by 285.5 kJ/mol to find the total energy released.
How much energy does a wind powered generator produce?
The Phillipe Starcke wind turbine is currently in design and is expected to generate about 60% of a house's energy. When it goes on the market it will be around $500.

How much carbon dioxide is generated from an electrical vehicle?
The same problem exists for both Electric and Hydrogen powered vehicles: Where does the Energy for the substances that these Alternate Energy Modes require come from? It currently comes from Coal.
How much hydrogen would be required to produce 7.5 mol of water?
To produce 1 mol of water, 2 mol of hydrogen is needed. Therefore, to produce 7.5 mol of water, you would need 15 mol of hydrogen.
How much energy does a car engine have?
A car engine is technically a heat engine that has no energy of its own but it converts the chemical energy in the fuels into heat and then into kinetic energy by turning a rotating shaft. The chemicals that react to make the engine work consists of carbon and hydrogen from the gasoline in the fuel tank, and oxygen taken from the atmosphere. The carbon reacts with oxygen to produce carbon dioxide and heat, while the hydrogen reacts with oxygen to produce water and heat.
Hydrogen is present in the center of the sun then why is it not used as a major source of energy as we are facing shortage of energy?
The technology doesn't currently exist to get reasonable amounts of energy from hydrogen fusion. It is hoped, however, that Deuterium - which is much easier to fuse than normal hydrogen - can be fused some time in the foreseeable future. The problem is that the hydrogen (or deuterium) would have to be heated to something like 100 million Kelvin (or Centigrade), and maintained at that temperature for a few seconds at least - and at a high pressure, too.
How much energy is needed to completely remove an electron from n2 in a hydrogen atom?
How much energy is required to move the electron of the hydrogen atom from the 1s to the 2s orbital
How much energy does an airplane engine produce?
The energy does a airplane engine produce is 10 kg of ht?
Why can the sun not be powered by a process such as the combustion of hydrogen and oxygen to form water?
Such a process would produce much, much less energy than nuclear reactions; the Sun would not be able to shine for billions of years, and producing the amount of energy it produces.Such a process would produce much, much less energy than nuclear reactions; the Sun would not be able to shine for billions of years, and producing the amount of energy it produces.Such a process would produce much, much less energy than nuclear reactions; the Sun would not be able to shine for billions of years, and producing the amount of energy it produces.Such a process would produce much, much less energy than nuclear reactions; the Sun would not be able to shine for billions of years, and producing the amount of energy it produces.
How much energy does a supernova produce during its explosive event?
A supernova can produce as much energy in a few seconds as our sun will in its entire lifetime.
