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 probabili
The reaction of methyl iodide with sodium hydroxide proceeds as follows with dichloromethane as the solvent: Ch2Cl2 Ch3I + NaOH ------------> CH3OH + NaI Clearly and unambiguously show what effects switching the solvents t water would have on the reaction coordinate diagram. Sketch this on the graph
I have my final report and I have 2 questions about it. So our final product was a brown crystalline solid that had an absorbance at about 880nm. My first question is how is brown reflected (not in a literal sense) in the visible spectrum? that's outside visible region and I could find nothing about brown solids and absorbance
In forming a chelate with a metal ion, a mixture of free EDTA (abbreviated Y^4-) and metal chelate (abbreviated MY^n-4) can buffer the free metal ion concentration at values near the dissociation constant of the metal chelate, just as a weak acid and a salt can buffer the hydrogen ion concentration at values near the acid dissoc

I have a few questions regarding a couple problems I had to do. I will attach the exercise so it is easier to read. For the first calculation of Kf, I couldn't find anywhere online or in my books on how to derive that calculation. For the next Ksp, I got 2.24x10^7. For the next one I got using the Nernst equation, E=1.07 for
