Awire is wrapped around a piece of iron, and then electricity is run through the wire. what happens to the iron? a. it becomes demagnetized. b. it becomes permanently magnetized. c. it becomes magnetized as long as the current flows. d. the polarity of the nail is reversed.

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
