1. Consider equimolar samples of different ideal gases at the same volume and temperature. Gas A has a higher molar mass than gas B. Compare the pressures. Compare the rms speeds. Compare the average kinetic energies.
A>B A>B A>BA=B A=B A=BA<B A<B A<B

The minimum frequency of light needed to eject electrons from a metal is called the threshold frequency, ?0. Find the minimum energy needed to eject electrons from a metal with a threshold frequency of 5.73 × 10^14 s-1.
a 5.00 gram sample of potassium chlorate/potassium chloride mixture was heated in a test tube. A total of 1.00 L of oxygen gas was collected over water at 25 degrees c and 741 torr. determine the percentage of potassium chlorate in the mixture.
Treating 1-butanol with sulfuric acid establishes an equilibrium with 1-butyl bisulfate and water as shown.
Starting with needed alkanes, alkenes and inorganic regrets, devise syntheses for the following compounds. Yout method should produce each compound in good yield and free of isomers.
A sample of gas is confined to a cylinder housed with a movable piston. The gas occupies a volume of 1.8 L at 1.8 atm and 25°C. Calculate the volume of the gas sample if the pressure is increased to 8.6 atm at constant temperature.
Two volatile liquids (A and B) form an ideal mixture at 300.0K which just begins to boil at a pressure of 0.3000 atm. The vapor pressure of pure component A is 0.5000 atm and the vapor pressure of pure component B is 0.2000 atm
Use this information to estimate the X-X (single-)bond energy in the X2H4 molecule.
Calculate the molarity of a solution made by adding 27.8 mL of concentrated hydrochloric acid (37.3 % by mass, density 1.19 g/mL) to some water in a volumetric flask, then adding water
Calculate the molarity of each of the following solutions. (a) 29.0 g of ethanol (C2H5OH) in 545 mL of solution
An automobile engine requires a carburetor or fuel inector to mix the fuel with air. The fuel and air must be mixed in a particlar ratio to achieve maximum efficiency in the combustion of the fuel.
describe an experiment that you could perform in lab that would provide the data so you could calculate the Ka value for sulfamic acid, HSO3NH2.
