Determine the ratio of ethyl a mine(CH3CH2NH2) to the ethyl ammonium ion (CH3CH2NH3+) in a solution with a pH of 11.0 pKa forCH3CH2NH3+ =10.636
Determine the numbers of grams of NaCH3COO must be added to 150.0 mL of a .150 M solution of CH3COOH to produce a buffer of pH4.75? Suppose that the volume will remain constant, pK A forCH3COOH = 4.757.
Illustrate the probability envelopes for each of the 3d-orbitals. Make sure that you indicate the positions of the axes(x, y & z) and the sign of the wave function for each portion on the orbital.
Suppose you conclude that the reaction order n=0 for a reaction with t half-life at 10 min, 20 min, and 40 min, because half-life is dependent on the concentration. But why can't the reaction be second order (n=2) where half-life is also concentra
Determine the numbers of grams of dry NH4Cl required to be added to 2.50 L of a 0.700 M solution of ammonia, NH3, to prepare a buffer solution that has a PH of 8.81? Kb for ammonia is 1.8x10^-5.
Suppose the correlation, r, between two variables x and y is -0.44. What percentage of the variability in y cannot be explained by x?
Determine the half-life of 90Y. A freshly isolated sample of 90Y was found to have an activity of 9.7 x 105 disintegrations per minute at the 1:00 P.M. on December 3, 2006.
If the activity of carbon-14 decay in an equal mass of living matter is 33.6 disintegrations per second, determine the age of the charcoal? The activity of radioactive carbon-14 decay of a piece of charcoal found at a volcanic site is 20.4 disint
