What is the temperature dependence of the jump rate ? where does it come from?~exp(-q/rt); it comes from the fact that at finite temperature the atoms exchange energy via vibrational ""collisions"".

Marcel just purchased 1.69 grams of iron fillings in order to make living putty for his 6 year old niece. how many moles of iron are made in his sample?

12. calculate the hydroxide ion concentration of a solution with ph = 3.25. show all calculations leading to an answer

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
