The reaction of toluene, C7H8, with potassium permanganate, KMnO4, gives a 70% yield. C7H8(I) + 2KMnO4 (aq) -> KC7 H5O2 (aq) +2MnO2(s) +KOH(aq) +H2O(I)

A) if 8.60g of C7H8 is reacted with excess KMnO4 what is the theoretical yield in grams of KC7H5O2?

B) what mass of KC7H5O2 can be expected?

Which statement is true according to the kinetic theory? a. molecules of different gases with the same mass and temperature always have the same average density. b. molecules of different gases with the same mass and temperature always have the same average volume. c. molecules of different gases with the same mass and temperature always have the same pressure. d. molecules of different gases with the same mass and temperature always have the same molecular mass. e. molecules of different gases with the same mass and temperature always have the same average kinetic energy.
