Problem- Anyone who can help with R and S nomenclature on enantiomers I tried the prioritizing of substituent groups and still missed several problems. The wording in the books is so thick and superfluous. Simply looking for help with an easy way to remember the clockwise and counterclockwise naming system.
Describe the bonding in N3- (Azide ion) in terms of an molecular orbital picture in which each terminal N atom is sp hybridized with one hybrid orbital accommodating one lone pair of electrons
The present limit of detection of THC in urine is 20 nangrams (1 nanogram =1*10^-9) per milliliter of urine (1milliliter = 1ML=1*10^-3L). Calculate the molarity of the solution at the limet of dection. Molecular weight of THC is 315 g/mol.
Calculate the pH of a buffer solution prepared by dissolving 0.20 mole of cyanic acid (HCNO) and 0.80 mole of sodium cyanate (NaCNO) in enough water to make 1.0 liter of solution. [Ka(HCNO) = 2.0 ? 10-4]
The volume of a sample of Cl2 is 5.62 L at 740 torr and 33 degrees celsius. What volume will the Cl2 occupy at 107 degrees celsius and 680 torr ?
What is the molar solubility of silver bromide in a solution that also contains 0.050M Ag+ ions at 25 °C? The Ksp of AgBr is 5.4 × 10-13.
Briefly discuss how the solubility, crystallization and extraction techniques aid one in separation of the components of "Panacetin".
Imagine a person accidentally swallows a drop of liquid oxygen, which has a density of 1.149 g/mL. Assuming the liquid drop has a volume of .075mL, calculate the volume that would be produced when the liquid vaporizes in the person's stomach at 37..
Find out the volume of a .750M K2Cr2O7 solution required to completely react with 5.10g Cu. The molecular mass of K2Cr2O7 is 294.185.
