Answer #1

If you talk about fuel combusiton...

then note that % of oxygen may be modified via:

- Enriched oxygen fuel... i.e. from air which contains only 21% of Oxygen, could be enriched up to 100%

- It is several times added in excess, to ensure combustion to form CO2 instead of CO

then...

for performance of combustion, it is clearly important that Oxygen is present

If we talk about high temperatures... we don't want as many Oxygen... because many times we will use the heat generated to "heat" or "increase the temperature" of the oxygen that is leftover...

Hydrogen is oxidized in a fuel cell to make electricity, by the (unbalanced) reaction: H2 + O2  H2O. 1 kg/min H2 is fed to the fuel cell, and oxygen is fed as 21% of air. The oxygen is fed at a rate 50% more than the minimum required to completely oxidize all the H2. Assuming that all the Hydrogen is consumed, find the molar flow rate of all chemical species leaving the fuel cell.

For 1 mole of an arbitrary alcohol (meaning it has oxygen bound in the fuel) such as CXHYOZ, and assuming complete combustion, find the number of moles of air required to burn 1 mol of fuel as a function of x, y, and z. Don’t forget to include the factor of 4.76 in the moles of air. Comment on how this compares with the moles of air required to burn a hydrocarbon fuel CXHY.

A mixture of propane and butane is burned with pure oxygen. The combustion products contain 46.7 mole% H2O. After all the water is removed from the products, the residual gas contains 68.8 mole% CO2 and the balance O2 a. What is the mole percent of propane in the fuel? % b. It now turns out that the fuel mixture may contain not only propane and butane but also other hydrocarbons. The fuel does not contain oxygen. However, the dry combustion...

6. A rocket is loaded with liquid oxygen fuel propellant in preparation for lift-off on a journey to the Moon. The total fuel ( in pounds) is stored in two separate tanks, each with different total fuel capacities. The total amount of fuel in both tanks is given by: F(t) = [(t- 6)^(-2)][(3t +5)^(5/3)]                 Where: F(t) is the total amount of fuel (lbs) in both tanks after t seconds of flight                                     t = the time in seconds;                 Assume: At t...

Sodium silicyde reacts with water to make hydrogen gas that can be used as a fuel. The reaction that accomplishes this has the balanced chemical equation: 2 NaSi(s) + 5H2O(l) → Na2Si2O5(s) + 5H2(g) Suppose a boat engine based on using hydrogen were devised using this reaction and sodium silicide is in a fuel tank (that reacts with water brought in from the body of water on which the boat operates). What happens to the mass of the fuel tank...

In analyzing the city and highway fuel efficiencies of many cars and​ trucks, the mean difference in fuel efficiencies for the 631 vehicles was 7.49 mpg with a standard deviation of 2.53mpg. Find a​ 95% confidence interval for this difference and interpret it in context. The​ 95% confidence interval for the difference in fuel efficiencies is left parenthesis nothing comma nothing right parenthesis, mpg. ​(Round to two decimal places as​ needed.)
