Honors correction
The file posted yesterday (020707) entitled, "Quiz that you could have had today! Allow only 12 minutes! " has an error on question 3d.
The equation should read MgCO3 (s) --> MgO (s) + CO2 (g)
The equation in the file has O2 as a product and no C, which is impossible because there is C in the carbonate anion on the reactant side.
Please make the correction because I cannot re-upload the file until late tonight.
Thank you and good luck tomorrow. There are not many tests this quarter due to the many, many vacation days so each test will weigh heavily towards your third quarter average.
p.s. DO NOT COME INTO CLASS WITHOUT A SCIENTIFIC CALCULATOR TOMORROW OR YOU WILL HAVE TO DO THE TEST WITH AN ABACUS OR A SLIDE-RULER (good luck with all that).
