1502 Chapter 15: Chemical Equilibrium Outline and Problems:
  • Write all answers in your bound journal
  • Make it NEAT and in COMPLETE SENTENCES, clearly identify which section you are working (using numbers)
  • Box final answers if doing math.
  • -4pt if you do not title and date the entry
  • -1pt (per infraction) if you do not clearly identify the sections, or number the problems

 
Section 3 & 5 (20pts)
