Air contains nitrogen, oxygen, argon, and trace gases. If the partial pressure of nitrogen is 587 mmHg, oxygen is 158 mmHg, argon is 7 mmHg, and the trace gas pressure is negligible, what is the atmospheric pressure?
If the gas was not pure butane but 10 mole percent propane and 90 mole percent butane then determine how would the MW value be affected?
Calculate brightness of a wavelength undergoing Rayleigh scattering.
What is the entropy change if two mole of liquid water is heated from 20 C to 100 C under constant pressure? Cp=75.5 J/mol*K over this temperature interval
The question is do you need to convert volts into something else when using it in the equation of (planks constant x speed of light / volts) or can I leave in volts? or should I convert volts to lambda?
Write equations for the preparation of the following alkenes by the Wittig reaction or the Wadsworth- Emmons modification of the Wittig reaction. Start with any carbonyl compound and Witting or Wadsworth- Emmons reagent together with any other org..
Calculate the change of volume of the cube at a depth of 1.000 km (disregarding the effects of temperature). Take the mean density of sea water as 1.03 g/cm3.
