When pure carbon is burnt in air some of it is oxidized to C02 and some to CO. If the molar ratio of N2 to 02 is 7.18 and the molar ratio of CO to C02 is 2, what is the percentage excess air used? Exit gases contain only N2, O2, CO and C02.

A pure, low molecular weight hydrocarbon gas is burnt in a furnace giving a flue gas...

A pure, low molecular weight hydrocarbon gas is burnt in a furnace giving a flue gas containing 10.8% CO 2 , 3.8% O 2 and the remainder nitrogen. Calculate the atomic ratio, H/C, and from this the formula of the fuel. Note that this analysis is on a dry basis. 2nd part: Calculate the analysis of the flue gases resulting from the combustion of ethane with 100% excess air. Give the results on a dry basis.

A coal with the following composition was burnt in a power plant with 25.0% excess air. Waht is the percent CO2 shown by Orsat analysis? The air drawn into the furnace at that location has 0.021 moles of water vapor per mole of dry air. Coal analysis: Carbon 64.0%; Hydrogen 4.3%; Nitrogen 1.1%; Sulfur 1.6%. The lab also reported that the coal contained 5.0% moisture and 13.7% ash.

One mole of carbon monoxide at 10 ºC is completely burnt at 1 atm pressure with...

One mole of carbon monoxide at 10 ºC is completely burnt at 1 atm pressure with 50% excess air. The air is fed to the burner at a temperature of 540 ºC. The combustion products leave the burner chamber at 425 ºC. Use a molar flow and enthalpy summary table to help organize your work. Draw a labeled PFD. Define your system. Analyze the energy balance relationship that applies to your system. Calculate the heat involved in this process, in units of kJ per mole...

When a plant grows, the atoms used come from carbon dioxide in the air and water....

When a plant grows, the atoms used come from carbon dioxide in the air and water. Plants are able to accomplish this through the process of photosynthesis, cellular respiration and biosynthesis of macromolecules. Where does the energy come from that allow plants to synthesize the necessary biological macromolecules that allow it to grow? Hint: It is NOT from sunlight. Explain your answer.
