Early in the day, Will learned about the kinds of changes in matter that can take place. He wanted to explore these changes in more depth, so he compared the two kinds of ways matter changes and how they differ He recorded his findings in his science notebook. What are the ways in which matter changes and how do they differ?β

Percent ionization for a weak acid (ha) is determined by the following formula: percent ionization=[ha] ionized[ha] initialΓ100%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 9.4Γ10? 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
