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.
Uranium fuel pellet used in nuclear power stations produce far more energy per kilogram than the energy produced by burning coal How much coal has to be burnt to produce the same amount of energy as?
1 kg of U-235 will produce as much energy as 1500 tons of coal
What carbohydrate do for your body?
carbohydrates breaks down to polysachorides->mono...-sugar> energy for the body to run => fuel of energy biol.242
Does nuclear fuel produce sixty eight percent of the electrical energy in US?
No, much less, about 20 percent at present
Hydrogen fuel cells combine hydrogen and oxygen to produce water and energy Assume 1 kg of fuel is used and the mass of the water produced is 1.10 x 10-11 kg How much energy is produced by this fuel?
do the math
What is renewable alternative to coal?
You can use many different things. some examples are: Bio-Fuel (still in development) Wind (not as reliable as coal) solar (doesn't produce as much energy as coal) hydro (doesn't produce as much energy as coal)
How much fossil fuel energy is used to produce 100 MW of electricity to a town?
i gotta do same question for my science assignment
How much coal has to be burned to produce the same amount of energy as is generated by a kilogram of uranium fuel pellet?
About 1500 tons of coal
Why do carbohydrates in the mitochondria produce more ATP than those outside the cell?
Because oxidation is complete. Much energy is conserved.
How much energy does wave energy produce?
500w
How much less carbon dioxide do fuel cell cars emit?
Fuel cell cars use hydrogen to drive the fuel cell in the car which generates electricity. The only emissions are water and heat. No carbon dioxide at all. (The production of the hydrogen will have a carbon footprint, unless it was produced using renewable energy.)
How much fuel does the average car produce a year?
Produce means to make/manufacture. Cars dont produce fuel - please restate the question.
