What holds the complexes together: The set of ligands are held to a metal ion by largely electrostatic forces (although there really is a high degree of covalency). The forces arise from the positive charge on the metal ion and the electric dipoles of the ligands‚ whose negative ends are associated with the donor atom lone pairs. See Chem 341. 2. What

After created the RAND()values‚ I copied and pasted the values in the column F4:F16 because I needed to freeze the number‚ otherwise it would keep changing. Using the random probabilities numbers created previously by the function RAND(). I used Excel function VLOOKUP to find the number of days needed to repair =VLOOKUP(F4‚LookUp‚2) to =VLOOKUP(F16‚LookUp‚2) and the sum gave me the information of number of

Vol. 1 ACETIC ACID 115 ACETIC ACID 1. Introduction Acetic acid [64-19-7]‚ CH3COOH‚ is a corrosive organic acid having a sharp odor‚ burning taste‚ and pernicious blistering properties. It is found in ocean water‚ oilfield brines‚ rain‚ and at trace concentrations in many plant and animal liquids. It is central to all biological energy pathways. Fermentation of fruit and vegetable juices yields 2–12% acetic acid solutions‚ usually called vinegar (qv). Any sugar-containing sap or juice can

Subsequent forecasts were derived by exponential smoothing. Using the exponential smoothing method‚ find the forecast time for period 5. (Hint: You need to first find the smoothing constant‚ α.) To find α: 50= 50 + α(42-50) -8α = -2 α = 0.25 F5 = 50 + 0.25(46 – 50) F5 = 49
