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
