Inorganic Chemical Reactions can be categorized into the following broad categories: combination reactions, decomposition reactions, single displacement reactions and double displacement reactions.
The Periodic Table is the arrangement of elements in tabular form based on atomic numbers and electronic configurations.
For questions 5-7, determine the oxidation state of the metal in each of the following complexes. Draw ALL linkage isomers and stereoisomers for each complex CLEARLY showing enantiomers. Where possible, label each isomer as cis, trans, fac, mer, Δ and/or Λ. You must properly use shorthand notation for multidentate ligands.

A mixture of Mn2+, Mg2+ and Zn2+ was analyzed as follows: The 25000 mL sample was treated with 0.25 g of NH3OH+Cl- (hydroxylammonium cgloride, a reducing agent that maintains manganese in the +2 state), 10 mL of ammonia buffer (pH 10), and a few drops of erichrome black T indicator and then duluted to 100 mL. It was warmed to 40
Consider the titration of 50.0 mL of 0.0110 M Y^3+ (y=yttrium) with 0.0220 M EDTA at pH 5.00. Calculate pY^3+ at the following volumes of added EDTA and sketch the titration curve: (a) 0mL (b) 10.0 mL (c) 25 mL (d) 30.0 mL.
Materials and Methods Protocol was titled Synthesis and application of a radical trapping agent was obtained from CHEM 3880-A1.

I am confused on how to approach these problems. This is an ungraded class review and I would like to understand before going to class, so I can ask additional questions. Thanks for the assistance. 2. Is a high spin or low spin d6 metal ion complex most likely to undergo substitution by a dissociative process? Explain the rea
I need help with this question: 1. Six-coordinate CR(3) complexes of the type trans-(CrL4A2)n+, generally have magnetic moments consistent with three unpaired electrons, which suggests occupancy of the d orbitals as shown to the right. In principle, a complex with only one unpaired electron could be generated by a suitable choi
4. Circle the letter corresponding to the correct answer for the following. For which of the following complexes can a tetralredral coordination geometry be unequivocally excluded based upon its magnetic properties? a) Cu(PPh3)3Cl (diamagnetic) b) P(PPhr3)2Cl2 (diamagnetic) c) Ni(PPh3)2Br2 (paramagnetic) d) Co(PPh3)2Cl2 (par
See the attached file. 3. A plot of the lattice energies for MCI; salts for M = Ca to Zn and a drawing of the cell are shown to the right. In the electrostatic model for "ionic bonding" U is proportional to (Z+)(Z-)e2A/(r+ + r.) where Z+ and Z- are the ion charges, A is the structure (Madelung) constant and r+ + r are the radi
Sir, I have located the articles and maybe one more. I am having trouble zeroing in on the right answer for the questions and format (like should I put it in a table) since formatting/clarity is graded. Also, how do I go about finding the articles. When I queried on the [Rh(PPh3)3(H)(CO)] or hydroformylation or whatever, I g
I am confused and frustrated on this topic. I do not know how to begin or exactly what is being asked. An explanation with work would be helpful. A question like this will appear on our next quiz. Thanks.
I have attached a question involving bonding and symmetry. I am totally confused on how to do this. Any explanation with work would be greatly appreciated. I am going to have similar problem on the next exam.
Obtain a 1H NMR spectra of the product in CDCl3 (given with this posting). Integrate the two low-field sets of peaks at 3.8 and 4.2 ppm, analyze the coupling constant (J) patterns to assign the two sets of peaks (as I discussed before, the MNova software auto assigns it for you), and report the percentage distribution of cis- an
I have attached the data in pdf form (GC information); document that is the peaks for NMR integrated (chloroform as the deuterated solvent) and a word doc in rich text (duplicating the excel format) that must be completed. I need assistance with calculations.
I need the cis and trans alcohol % from the attached information received by GC. The solvent was methanol. I believe this is done by using the peak area but I'm not sure about how to go about it.
I need help finding the cis and trans alcohol % of the H'NMR from the attachment. The deuterated solvent was chlorform. I have rerun with auto integration but don't know to find j value, I am new the software MestReNova.

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
