In an experiment from last semester, many of you observed a green solution containing [Ni(H2O)6]2+. Upon adding ethylenediamine (en), you observed a blue (blue) solution containing [Ni(en)2(H2O)2]2+. What does this indicate about the relative size of the crystal field splitting for the water ligand compared to the ethylenediamine ligand? And how do you know?

A 42 year old mother has two different alleles for the X chromosome, A1 and A2;

A 42 year old mother has two different alleles for the X chromosome, A1 and A2; the father’s X has allele A3.A) (3 point) Their son is found to have a single bar body in the nucleus of his cells. He was genetically tested and found to have both the A1 allele and the A3 allele. Describe in detail the defect in meiosis that would make this possible. A narrative or a diagram is an acceptable answer.B) (2 point) Their…

In a popular amusement park ride, a rotating cylinder of radius 4.00 m is set in

In a popular amusement park ride, a rotating cylinder of radius 4.00 m is set in rotation at an angular speed of 6.00 rad/s, as in Figure P7.51. The floor then drops away, leaving the riders suspended against the wall in a vertical position. What minimum coefficient of friction between a rider’s clothing and the wall is needed to keep the rider from slipping? (Hint: Recall that the magnitude of the maximum force of static friction is equal to µn,…
