The reaction observed in this video is the precipitation of lead iodide from solutions of lead nitrate and potassium iodide. Pb(NO3)2(aq) + 2 KI (aq) → PbI2(s) + 2 KNO3(aq) Does this reaction conform to the law of conservation of matter?

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
