Calculate the heat required to convert 24.0 g of C2Cl3F3 from a liquid at 12.00°C to a gas at 56.00°C
Aerosol cans carry clear warnings against incineration because of the high pressures that can develop upon heating. Suppose a can contains a residual amount of gas at a pressure of 755mm Hg and a temperature of 25 C
if CO2 gas is collected over water at 25 degrees C and 775torr, what is the partial pressure of the CO2? The vapor pressure of water at 25degrees C is 23.8torr.
