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.
Which gas is both harmful and beneficial?
Oxygen is a gas all animals need to live, but too much can kill, and the presence of oxygen enables combustion (fire).
How much oxygen does a patient undergoing oxygen therapy receive?
The physician will prescribe the specific amount of oxygen needed by the patient.
How much combustion energy is released from two Hydrogen Atoms and one Oxygen Atom?
478 KiloJoules per mole
If hexane was burned in a limited supply of oxygen the combustion would not be complete?
This depends on how much hexane was being burned and how much oxygen was present.Because the complete combustion of carbon involves placing two moles of oxygen on one mole of carbon plus the formation of water, you would need 19 moles of diatomic oxygen for every one mole of hexane.1 C6H14 + 19 O2 --> 6 CO2 + 7 H2O
How much oxygen is needed to sustain the burning process?
15%
What is the difference between respiration and combustion?
combustion is a burning of carbohydrate molecule in the presence of oxygen in blood while respiration is process of breathing through which the body and blood gets oxygen.
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.
How do you calculate the ammount of air to burn a given fuel?
First work out the balanced Chemical equation for the combustion of the fuel concerned. That will give you the amount of Oxygen needed. Convert the amount of fuel to be burned into to molar quantities and this will in tun tell you haw many moles of Oxygen will be needed. You then need to determine how much air (say by volume) contains that number of moles of Oxygen, given that air is only 21% oxygen.
How much oxygen takes to burn propane?
C3H8 + 5O2 -> 3CO2 + 4H2O That is the complete combustion for Propane.
How hot is a charcoal fire?
Really Hot! :D I hope that helped!' Depends how much oxygen is added as oxygen does not burn BUT it does vigorously support combustion
How much oxygen is needed by a human body?
A lot
Which gas is both harmful and beneficial?
Oxygen is a gas all animals need to live, but too much can kill, and the presence of oxygen enables combustion (fire).
Can mars sustain human life?
No, Mars can't sustain human life because there is too little oxygen, too much carbon dioxide, and it is too far away from the sun to sustain a warm enough temperature for life here on earth.
Can you ignite Neptune?
No, you can't ignite Neptune. While much of Neptune's atmosphere is hydrogen, there is no oxygen there to support combustion.
What does engine running rich or lean mean?
An engine runs by the combustion of a mixture of oxygen and gasoline. If this mix has too much oxygen, it is said to run lean. When the mixture has too much gasoline in relation to oxygen, it is running rich.
How much oxygen does a patient undergoing oxygen therapy receive?
The physician will prescribe the specific amount of oxygen needed by the patient.
