Remember we are having a review day for naming compounds and writing chemical equaitons on Monday, November 16th. On Tuesday, November 17th, we will be having a review over mole conversions, percent composition and empirical formulas. YOU MUST BE AT ONE OF THESE SESSIONS IN ORDER TO RETAKE A QUEST.
We are starting stoichiometry notes with a cool lab by the end of next week maybe. Read the packet I gave you to be ready for class on Monday.
