Nitrogen oxide is a pollutant in the lower atmosphere that irritates the eyes and lungs and leads to the formation of acid rain. Nitrogen oxide forms naturally in atmosphere according to the endothermic reaction: N2+O2=2NO(g) Kp= 4.1x10^-31 at 298K
1) Use the ideal gas law to calculate the concentrations of nitrogen and oxygen present in air at a pressure of 1.0atm and a temperature of 298k . Assume that nitrogen composes 78% of air by volume and that oxygen composes 21% of air.
2) Find the "natural" equilibrium concentration of NO in air in units of molecules/cm3.
The solubility of silver sulfate in water is 0.223% (w/v) at 35°C. Calculate the solubility product of this salt at this temperature
How many air molecules are in a 11.5 * 12 * 10 room? Assume atmospheric pressure of 1.00 atm a room temperature of 20.0 Celsius and ideal behavior.
Constant external pressure of3.00 atm, followed by2) against a constant external pressure of 2.00 atm. Calculate q and w. (101.33 J = 1 L atm)
Properties of subatomic particles - Fill in the missing relative masses and relative charges for each of the subatomic particles
Assume that we are comparing the membrane fluidity of lipid bilayers. Rank the fluidity of the following bilayers in the order of increasing fluidity. Explain in each case the rationale behind your prediction
1) How many moles of oxygen atoms are present in a sample that contains 3.86 moles of dioxygen difluoride O2F2? The answer I got from this was: 7.72 moles of O2 atoms?
