Question #1: If 200 mL of 0.300 M Cr(NO3)3(aq) is added to 100 mL of 4.0 × 10^-4 M NaF(aq) at 25 degrees celcius, will a CrF3 precipitate form? For CrF3 in water at 25°C, Ksp = 6.6 × 10^-11.

Question #2: The 3dxy orbital has its high probability regions lying between the x and y axes. The 3dz2 orbital has its high probability regions mainly on the z axis. The ligands in a complex ion with coordination number six lie on the x, y, and z axes. Which statement is true for the orbitals in this complex ion?
(a) The 3dxy and 3dz2 orbitals have the same energy.
(b) The 3dxy orbital has a higher energy than the 3dz2 orbital.
(c) The 3dxy orbital has a lower energy than the 3dz2 orbital.
