17) As the atoms in Period 3 of the Periodic Table are considered from left to right, the atoms generally show A) an increase in radius and an increase in ionization energy
B) a decrease in radius and a decrease in ionization energy
C) a decrease in radius and an increase in ionization energy
D) an increase in radius and a decrease ionization energy

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
