5. Which description accurately describes the relationship between speed of fall and mass? Mass (g) Speed of Fall (m/s)
20 12
25 12
30 12
35 12
40 12
a. There is no relationship between the speed
of fall and mass

b. The speed of fall is proportional to the
square of the mass

c. The speed of fall is inversely proportional to
the mass

d. The speed of fall is directly proportional to
the mass

Percent ionization for a weak acid (ha) is determined by the following formula: percent ionization=[ha] ionized[ha] initial×100%for strong acids, ionization is nearly complete (100%) at most concentrations. however, for weak acids, the percent ionization changes significantly with concentration. the more diluted the acid is, the greater percent ionization.a certain weak acid, ha, has a ka value of 9.4×10? 7.part acalculate the percent ionization of ha in a 0.10 m solution.part bcalculate the percent ionization of ha in a 0.010 m solution
