Problem- If the [FeSCN]std is 3.50x10^-4 M and the absorbance at equilibrium is 0.162 and the absorbance of the standard is 0.299, calculate the [FeSCN]eq.
I need proficient help to solve the above problem
Many important drugs contain the amine functional group, which makes them basic. Many drugs also contain an amide group, which is effectively neutral. Suggest a way to separate ephedrine, a stimulant and decongestant drug shown below
Solid CrF3 contains a Cr(III) ion surrounded by six F- ions in an octahedral geometry, all at distances of 190 pm. However, MnF3 is in a distorted geometry with Mn-F distances of 179, 191, and 209 pm (two of each). Suggest an explanation.
Compute the packing efficiency for an fcc lattice, keeping in mind that the close-packing direction is along the body diagonal, yielding a row of atoms along a face diagonal (i.e., the face diagonal = 4r). How does this compare to primitive cubic ..
