Calculate the ratio of diffusion rates for carbon monoxide and carbon dioxide.

What is the partial pressure of hydrogen gas in a mixture of hydrogen and helium if the total pressure is 600 mmHg and the partial pressure of helium is 439 mmHg?

What factors affect the rate of diffusion of oxygen and carbon dioxide?

Find the partial pressure of carbon dioxide in a gas mixture with a total pressure of 30.4 kPa if the partial pressures of the other two gases in the mixture are 16.5 kPa and 3.7 kPa.

What is the molar mass of a gas dial takes three times longer to effuse than helium?

Determine the locus of centers of all circles passing through two given points. Give an accurate, simple description of the locus.

When solid sugar crystals are dissolved in a glass of water, they form a clear homogeneous solution in which the crystals are not visible. If the beaker is left out at room temperature for a few days, the crystals reappear in the bottom and on the sides of the glass. Is this an example of freezing?

Write the formula for each molecule. bromous acid

Compare and contrast intermolecular forces and describe intramolecular forces.

Two vessels are labeled A and B. Vessel A contains NH3 gas at 70 degree C, and vessel B contains Ne gas at the same temperature. If the average kinetic energy of NH3 is 7.1*10^(-21) J/molecule, calculate the meansquare speed of Ne atoms in m2/s2.

Consider the following gases, all at

$$\mathrm { STP } : \mathrm { Ne } , \mathrm { SF } _ { 6 } , \mathrm { N } _ { 2 } , \mathrm { CH } _ { 4 }$$

Which has the highest average kinetic-molecular energy?

Explain what determines a substance's state at a given temperature.

A 2.00-L flask is filled with propane gas $\left(\mathrm{C}_{3} \mathrm{H}_{\mathrm{8}}\right)$ at a pressure of 1.00 atm and a temperature of $-15.0^{\circ} \mathrm{C}$. What is the mass of the propane in the flask?

A gas at $89^{\circ} \mathrm{C}$ occupies a volume of 0.67 L. At what Celsius temperature will the volume increase to 1.12 L?
