I need help figuring out the solution to this problem and am unsure where to start. Can you please show all work and steps so I can understand the calculations.
1. Pyridine (C5H5N) is a weak base with a pKb of 8.77. Write the Kb expression for this reaction.
p in pKb is equal to negative logarithm.
In the solution shown below, log on right hand side becomes antilog which is 10 raised to the power -8.77.

I need help figuring out how to approach a problem. I need to determine the initial velocity of an object for it to be at a specific height at a specific time. For example, what would the initial velocity of an object need to be for it to be at 38.7m @ 4.7 seconds if thrown straight up from the ground (launched up at 90 degrees)? If I understand correctly, there could be two answers, one for the initial trip...
Determining Ionic StrengthUnlike strong acids and bases that ionize completely in solution, weak acids or bases partially ionize. The tendency to ionize (i.e., the ionic strength) of a weak acid or base can be quantified in several ways includingKa or Kb,pKa or pKb,and percent ionization.Part APyridine is a weak base that is used in the manufacture of pesticides and plastic resins. It is also a component of cigarette smoke. Pyridine ionizes in water as follows:C5H5N+H2O?C5H5NH++OH?The pKb of pyridine is 8.75....
