A mixture of 70 mole% propane and 30 mole% hydrogen is burned with 30% excess air. Fractional conversions of 90% of the propane and 85% of the hydrogen are achieved; of the propane that reacts, 90% reacts to form CO2 and the balance reacts to form CO. The hot combustion product gas passes through a boiler in which heat transferred from the gas converts boiler feedwater into steam.
(A) Calculate the concentration of CO (ppm) in the stack gas.
The reactant concentration in a zero-order reaction was 8.00×10-2 after 100 and 4.00×10-2 after 370 .
is it possible to use methylene blue to determine the concentration of ascorbic acid in orange
Ethanol (C2H6O), the intoxicant in alcoholic beverages, is also used as a precursor of many other organic compounds. In acid solution, ethanol forms diethyl ether (C4H10O)
A gas measures 180. ml. at 870C and 800. mm Hg. Find its volume at standard temperature and 800 mm Hg of pressure.
The mass of an average blueberry is 0.72 g and the mass of an automobile is 1900 kg. Find the number of automobiles whose total mass is the same as 1.0 {rm mol} blueberries.
Explain using resonance and inductive effects why trifluoroacetic acid (Pka = -0.25) is more acidic than ethanol (pKa = 16?
We are investigating the keto-enol tautomerization of acetylacetone (pentane-2,4-dione) in an aqueous solutions at 25 degrees Celsius. The standard reaction Gibbs energy for the enol ketone tautomerization is -3.64 kJ/mol.
An unknown volume of water at 18.2 degrees Celsius is added to 21.6 mL of water at 35.0 degrees Celsius. If the final temperature is 23.5 degrees Celsius, what was the unknown volume
Calculate the work(in kilojoules) done during a synthesis of ammonia(see reaction below) in which the volume contracts from 8.6L to 4.3L at a constant external pressure of 44atm.
When making an alcoholic beverage, such as beer and wine, Brix is a measurement used to assess the amount of sugar present in the fermentation matrix or grape juice.
A gas occupies a volume of 1.0 L at a temperature of 27°C and 500 torr pressure. calculate the volume of the gas if the temperature is changed to 60°C and the pressure to 700 torr
Explain why C-H single bond stretching is observed in the functional group (higher energy) region of the IR, but the absorptions corresponding to other single bond stretching vibrations
