Materials that are good conductors are so because

A. They are positive and always attract electrons
B. The protons are relatively mobile.
C. Some of their electrons are free to roam through the atomic structure
D. All of their electrons can be completely removed from the nucleus.

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
