What are the SI units for
(a) wavelength,
(b) frequency,
(c) period, and
(d) amplitude?
How many values of amplitude are there in one wavelength of a wave, and how is the amplitude related to the energy of a wave?
Ions B and C react to form complex BC. If 20.0mL of 1.25M B is combined with 20.0mL of 1.25M C, 0.00650 mol of complex BC is formed. Determine the equilibrium constant for this reaction.
