Some liquid samples cannot be injected directly into an HPLC system because they could either damage the column or the HPLC system. For these samples, solid phase extraction (SPE) is used prior to analysis. Explain SPE? ( I have som eideas, but having a hard time keeping it short and to the point)
Place drying tube filled with CaCl2 on condenser. Heat to reflux at 190 C for 25 minutes then cool. Add 0.5mL tolulene and petroleum ether 0.5-0.75 mL until slight cloudiness remains. Reheat until clear and cool in ice bath. Collect product and wa..

A truck is initially 6.0km north of the gas station and is moving with a constant speed of 45km/h due south. How far are the vehicles from the gas station when they pass each other
Liquid sodium is being considered as an engine coolant. How many grams of liquid sodium (minimum) are needed to absorb 4.00 MJ of energy (in the form of heat) if the temperature of the sodium is not to increase by more than 10.0 °C? Use CP = 30.8 ..
The solubility of nitrogen gas in water at 0 degree celcius and 1.0 atm is 23.54 mL per liter of the solution. (a) Calculate the Henry Law constant at 0 degree celcius
Carbon monoxide and water vapor, each at 190 Torr, were introduced into a 250 mL container. When the mixture reached equilibrium at 690 ?C, the partial pressure of CO2(g) was 108 Torr.
The difference between these forces is why some solids dissolve by an exothermic reaction (release heat), while other solids absorb heat and cool the solution. For an ionic solid dissolving in water, briefly identify the attractive
