Explain how much purified aspartic acid would you wait for to recover (assuming no losses due to technique) and define the missing L-aspartic acid?
How to calculate the concentration of these species at equilibrium
Demonstrate how you could prepare each of the following compounds from Propane and any necessary organic or inorganic reagents.
The emission spectrum for a one-electron ion in the gas phase. All the lines result from electronic transitions from excited states to the n=3 state. If the wavelength of line B is 142.5 nm, calculate the wavelength of line A.
An aqueous solution containing 5.38g of an optically pure compound was diluted to 200.0 ml with water placed in a polarimeter tube 20.0cm long. The measured rotation was -3.43degrees at 25 C. Calculate the specific rotation of the compound.
a constant volume container holds an equilibrium mixture of cl2g pcl3g and pcl5g gases which have partial pressures
