At an altitude of 45.00 km, the average atmospheric temperature is essentially ... - 115. At an altitude of 45.00 km, the average atmospheric temperature is essentially 0 degrees C. What is the average number of air molecules per cubic centimeter of air at this altitude?
Problem with Henry's constants and partial pressures - Consider the following aqueous route to oxidize SO2:
SO2(aq) + H2O2(aq) -> H2SO4(aq) k = 1.1 X 10^3 L/mols
a. The partial pressure and Henry's law constants for SO2 and H2O2 are 2.1 ppm (KH = 1.2 mol L-1atm-1) and 4.8 ppb (KH = 1.0E5 mol L-1atm-1), respectively. Calculate the reaction rate of this process.
b. Calculate the reaction rate...
NTA fraction, given pH and HCO3 concentr - What is the fraction of NTA present after HT2- has been brought to equilibrium with solid PbCO3 at pH 7.00, in a medium in which [HCO3-] = 1.00E-3 M?
Hint: Use the equilibrium constant expression to solve this problem.
I used a couple of study guides but could not get the right answers..please help, thanx!
average steady state concentration of 222Rn - Radioactive radon gas (222Rn) enters an average building at a rate of
5 picocuries per second per square meter of foundation area. Consider
a house with a foundation of 400 square meters and a volume of 1000 cubic
meters. Assume the house if well designed for energy conservation so that
the ventilation rate is low and only one tenth of the air ...
