Locate electronic spectral parameters for the tris(ethylenediamine)nickel(II) ion in solution and the magnetic moment (in Bohr magnetons) for a salt (indicate the counter ion). Spectral parameters should include: wavelengths of absorption maxima (A.), extinction coefficients (E) IODq (lODq is the same as 80) Racah parameter B.
Note that there are three spin-allowed transitions for octahedral Ni(II) in the region 300-1000nm. Primary literature references to all data must be provided.
Describe an incident (fire, spill, explosion, etc) you have experienced (or research one on the Internet, professional journal, or scientific magazine article) that involved a hazardous organic material(s) and required mitigation.
Consider a container of volume 2.0 dm3 that is divided into two compartments of equal size. In the left compartment there is nitrogen at 1.0 atm and 25°C; in the right compartment there is oxygen at the same temperature and pressure
Calculate the specific heat capacity of nickel from these experimental data, assuming that no heat escapes to the surroundings or is transferred to the calorimeter. Specific heat of water = 4.184 J/g oC atomic mass Ni = 58.7 g/mol Calculate your a..

Draw 2 resonance structures for each of the following molecules. Calculate the formal charge for each atom and indicate whether the structures are equivalent. Benzene, C6H6
how does the strength of the attraction between water molecules and sodium and chloride ions compare with the strength
The arrangement of the orbitals is the same in a multielectron atom and a single-electron atom. In the Li atom, the 3s, 3p, and 3d orbitals have different energies. The He atom has one electron each in 1s and 2s orbitals.
how much energy is required to vaporize 48.7 g of CH2Cl2 at its boiling point if its Hvap = 31.6 kg/mol
Suppose that a molecular orbital has the form N(0.145A + 0.844B). Find a linear combination of the orbitals A and B that has zero overlap with this combination.
Explain why the atomic mass of an atom is a decimal number and how that value was determined before being placed on the periodic table.
The difference between a law and a theory is the difference between what and why. Explain.
suppose a reaction mixture when diluted with water afforded 300mlof an aqueous solution of 30g of the reaction product
