An aerosol spray can with a volume of 270 ml contains 3.0 g of propane gas as propellant. what is the pressure in atms if the can is 20 degrees celsius?
Need to prepare a solution of 0.2 L 0.4 M then determine how many cm^3 of a solution of H2SO4 (sulfuric acid) 80.0%
At 373 K, Keq = 2.39 for the following reaction: SO2Cl2(g) = SO2(g) + Cl2(g) In an equilibrium mixture of the three gases, the partial pressures of SO2Cl2 and SO2 are 3.31 atm and 1.59 atm, respectively.
There are very few compounds that contain an element from the noble gas family (elements in column 18, rightmost column). Explain why there are so few noble gas compounds in nature.
