Show that wave function(x)=cos(npix/L+pi) is a solution to the schrodinger equation for a particle in a box with infinite potential at x=0 and x=l where n is an integer. Normalize the function. Test whether these wavefunctions are orthogonal for different values of n.
Suppose a solution contains 0.25 M Pb2 and 0.49 M Al3 . Calculate the pH range that would allow Al(OH)3 to precipitate but not Pb(OH)2
Phosphoric acid can be prepared by reaction of sulfuric acid with "phosphate rock" according to the equation: Ca3(PO4)2+3H2SO4 ---> 3CaSO4 + 2H3PO4 What is the molar mass of Ca3(PO4)2?
we need to form a cyclohexanone with a methyl group at the 6 position and a 2,3-butanediol group (with both OH groups at the back (dashed lines)) at the 2 position. All carbons on the target need to come from the starting materials, but other than..
