Caffeine (C8H10N4O2) is a weak base that is related to ammonia. For the purposes of this question, we will abbreviate the formula of caffeine
to CafN (producing cafNH+ in solution).
For a 0.70 M solution of CafN (Kb = 4.1 x 10-4), :

b) Determine the concentration of H3O+ and OH-. Show all your
entire process. [4]

c) Determine the pH and pOH. Show your work. [2]

Those are different gas lawshere is a brief description of themcharles's law states that volume and temperature are directly proportional to each other as long as pressure is held constant.  boyle's law asserts that pressure and volume are inversely proportional to each other at fixed temperature.gay-lussac's law introduces a direct proportionality between temperature and pressure as long as it is at a constant volume.    source:

The answer to your question would be  h+ + cn– + li+ + oh– mc001-4.jpg li+ + cn– + h2o. the total ionic equation for the following reaction is  h+ + cn– + li+ + oh– mc001-4.jpg li+ + cn– + h2o.
