Phosgene decomposes by the reaction COCL(g) CO(g) + Cl2 K2=8.3x10^-4 (at 360C) When 5.00 mol of COCL2(g) are placed in a 10.0 L flask, find the quilibrium concentration of COCL2, CO and CL2 using the follow steops a) write out the quadratic equation B) show if this is a valid assumption
A 55.0-{ g} piece of ice at 0.0 C is added to a sample of water at 8.0 C. All of the ice melts and the temperature of the water decreases to 0.0 C.
The slope of the Gran Plot for the titration of KHP with NaOH was found to be -1E-05. Use this to determine ka2. Other values that may be of importance: concentration was measured
 What is the pH of the acidic solution before titration? 4.  What is the pH of the reaction mixture after 10.0 mL of NaOH was added?
A 1.00L Solution contains 3.50x10^-4 M Cu(NO3)2 and 2.20x10^-3M ethylenediamine(en). The kf for Cu(en)2^2+ is 1x10^20. What is the concentration of Cu2+(aq) in the solution
Protein Quantification :why did you choose one standard curve over the other for analysis of your unknown?
An analyst is to determine the molarity of a NaOH solution. Three aliquots of standard KHP are weighed out 0.3078g, 0.4967g, and 0.3821g
Calculate the CO3- concentration of a 5.45 x 10-4 M H2CO3 (carbonic acid) solution. Ka1 and Ka2 of carbonic acid are 4.3 x 10-7 and 4.8 x 10-11 respectively.
although even more strained than cyclopro-panone, is nevertheless quite stable and can even be distilled. Explain, taking the polarity of the carbonyl group into account.
Consider the following unbalanced reduction half equation. MnO4-+H=+e- > Mn2++H2O. How many H= are needed for the balanced half-equation.
Explain why it is unnecessary to run both of the following reactions: zinc + copper (II) sulfate, copper + zinc sulfate
A vapor composed of 0.45 mole fraction ethanol and 0.55 mole fraction acetic acid at 120.0 mmHg (absolute), is in equilibrium with a liquid phase also composed of ethanol and acetic acid.
draw the structure of the expected dichlorocarbene adduct of methyl methacrylate. another product could have been obtained. It is the chloroform adduct to the double bond (Michael type reaction). what would this structure look like.
