The pressure of an unknown gas is measured with a manometer. The pressure is measured as 673 mmX. What is the pressure in mmHg? Instead of mercury the manometer is filled with a liquid (X) whose density is 0.575 g/cc.
If a solution contains 57.2% H2O, 32.6% HDO and 10.2%D2O by mass, what is DS, DG, DV and DH for the separation process if the temperature is 21 °C? Liquid chromatography can be used to separate compounds.
If P is fixed can T vary if a solution of 0.1 mol al AgNO3 in water saturated with AgCl and AgBr (both solids present), is placed in an evacuated vessel of larger volume than the solution. List all the components present.
The volume of the mixture is 1.7 L and its total pressure is 0.810 atm if zinc metal is added to hydrochloric acid to generate hydrogen gas and is collected over a liquid whose temperature is the same as pure water at 20.0 degrees C (18 torr).
