Going from a 72% to a 94% is a very impressive leap, for me. Particularly if the test consisted of only numericals. I am also glad that this test also covered chapter 5, a bit like a retake of ch.5. Thus the previous test of 72% is not worth as much. This test was also the largest test given so far since it covered all the mathematical concepts of chapter 5 to 7. Questions could consist of determining the empirical as well as the molecular formula, the mass percentage of a specific element in a compound or of the entire compound, determine the limiting reactant, determine the moles needed of an element or compound to react with different one(s).
