2. Using the concentration of the H2SO4 and the balanced equation for the reaction in Lab 9, determine the volume of acid necessary for the titration of 6.9 moles of oxalate salt and then for the titration of 0.3123 grams of sodium oxalate. Why is the second volume more practical

The characteristics of two different types of reactions are shown below: reaction a: electrons are gained by the atoms of an element. reaction b: protons are lost by the atom of an element. which statement is true about the atoms of the elements that participate in the two reactions? their identity changes in both reaction a and reaction b. their identity changes in reaction a but not in reaction b. their identity changes in reaction b but not in reaction a. their identity remains the same in both reaction a and reaction b.
