Additional Info
  • Do page 260 #2, 3a, 4-5 and p. 277 #7, 9, and 10a-e
  • Do p. 270# 1-4. (Hint: For #4, it is very helpful to write a word equation for each one first....THEN write the formula under each word. and only THEN try to balance the equation!) Do them the way we have gone over in class.
  • If you didn't already, complete the 2-sided worksheet on balancing equations and predicting reactions (which was handed out during class on Thursday, and which you worked on in class with Mrs. Christiansen). See the following hints:
    • Hint #1: Remember to list the TYPE of reaction (of the 5 types) in addition to balancing on the front side.
    • Hint #2: On the bottom and back, it REALLY helps to try to do a word equation first, then write the correct formulas, and THEN balance. When students try to jump right to the balancing, they often make lots of mistakes.
    • Hint #3: remember your 7 diatomic elements, all of which end in -gen or -ine. ex. hydroGEN, oxyGEN, chlorINE, etc.) They are diatomic when alone (as an element), not when part of a compound.
