Estimate the crystal field stabilization energy for the octahedral ion hexacyanochromium(III) , if the wavelength of maximum absorption for the ion is 375 nm.

To prevent the presence of air, noble gases are placed over highly reactive chemicals to act as inert "blanketing" gases. a chemical engineer places a mixture of noble gases consisting of 4.37 g of he, 13.36 g of ne, and 36.65 g of kr in a piston-cylinder assembly at stp. calculate the partial pressure in torr of kr.
