What intermolecular forces are present in Ethyl Alcohol and why does it have a lower boiling point than water (h2o)
A cylinder, with a piston pressing down with a constant pressure, is filled with 1.90 mole of a gas (), and its volume is 40.0 liter (). If 0.400mole of gas leak out, and the pressure and temperature remain the same, what is the final volume of th..
Carry out a calculation that would show only Al(OH)3, but not Mg(OH)2, will form precipitate in a solution that contain 0.10 M Al3+ and 0.10 M Mg2+ if the solution is buffered at pH = 9.00.
Two peaks on chromatogram have k1= 3.1 and k2= 4.9. Column efficiency is 2000 theoretical plates, void volume is 1mL. calculate the resolution between these compounds.
How could you use a conductometric titration to determine the molarity of either reacting solutions, assuming you knew the concentration of one
if a 210 mg piece of gold (density=19.32 b/cm^3) is hammered into a sheep measuring 2.3*10 ft. what is the average thickness of the sheet in meters?
A student prepared a saturated solution of copper (II) tartrate by cooling it to 10 degrees C. While the solution was still cool, the concentration of copper (II) was determined. How would the value of the solubility product (Ksp) be affected? Exp..
One of the students in lab decided to use two fractionating columns (one on top of the other) instead of just one. How would this: a) affect the separation between hexane and heptane?
