For the Particle-on-Sphere problem, solve for the following. a) For the l = 0 state determine the average angular momentum. L ?^2=-?^2 ?^2 ?^2=(1/(?sin?^2 ?) ?/(??^2 )+1/sin? ?/?? sin? ?/??) b) For the l = 2, ml = -1 state determine the average angular momentum and the average angular momentum in the z-axis
Calculate the pH in the solution formed by adding 10.0 mL of 0.100 M HCl to 20.0 mL of 0.100 M NH3
What is the minimum volume of water needed to recrystallize 50 mg of phthalic acid? How much phthalic acis will remain in solution after recrystallization?
Calculate the concentration of the acetate ion (mol/L) in a solution prepared by dissolving 1.00×10-2 mol of HCl(g) in 1.00 L of 9.00×10-1 M aqueous acetic acid. Equilibrium constants may be found in an appendix to your text.
If matose is made up of two alpha D-glucose units connected together by an alpha(1-4) linkage, how can it give a positive test as a reducing sugar?
Concentrated hydrochloric acid, HCl, has a composition of 37.5 %. The solutes molar mass is 36.461 g/mol. You may assume the molar mass of water is 18.015g/mol.
