  1. 12/19/2010 Standards: Many Objectives: a. Check for understanding with Test 2 - Ch 2,3,4,5,6,8, & 9 DO NOW: 1. Clear floor and tables: You will want calculator, pencil, scantron, and help sheet. HOMEWORK: 1. ChemThink.com (10 pts) Due tonight by 12:00 midnight ========================================================= STAMPS: NONE ChemThink.com (10 pts) Due tonight by 12:00 midnight

  2. Spotlight.exe 12/20/2010 Standards: 3(Stoichiometry & Conservation of Mass) Objectives: a. Be able to balance simple chemical equations b. Be able to recognize: coefficients, reactants, & products HOMEWORK: 1. SN Ch 10.1 p. 125-128 (4 pts) Std 3 2. Ch 10.1 PP's, p. 279 1-3 (1 pt) Std 3 ========================================================= STAMPS: NONE

  3. Name:_________________ Date: 12/19/11 Per:_____ DO NOW: 1. Balance these equations: a. ___ HgO ---> ___Hg + ___O2 b. ___ Zn + ___ HCl --> ___ ZnCl2 ___ H2 Continue to take notes on everything requested by the video and turn in at end of period (5 pts)

  4. Std 3

  5. Spotlight.exe DO NOW: 1. Balance these equations: a. ___ HgO ---> ___Hg + ___O2 b. ___ Zn + ___ HCl --> ___ ZnCl2 ___ H2 1 2 Coefficient - the number in front of each element/compound in an equation

  6. Spotlight.exe LEFT RIGHT Reactants Products Cu(s) + AgNO3 (aq) -----> Ag(s) + Cu(NO3)2(aq) The LAW of CONSERVATION OF MASS requires that we balance chemical equations

  7. Link for video showing reaction of copper wire (Cu) with silver nitrate solution ( AgNO3 ) http://www.mrwiggersci.com/chem/Smart-Board-Activities/Ch10-Chemical-Reactions/Cu-plus-AgNO3-vid.mpg Spotlight.exe link If watching at home, click here to see vide Cu(s) + AgNO3 (aq) -----> Ag(s) + Cu(NO3)2(aq) 2 1

  8. __H2 +__O2 --->__H2O 2 1 Work through this sample together, or click on the video file below to watch, listen, and learn how to balance a chemical equation. Video Tutorial Answer 2H2+ O2 2H2O balancing chemical equations.avi

  9. Balance the following equation. __C+ __Cl2 ---> __CCl4 2 1 Answer C+ 2Cl2 CCl4

  10. __CaCO3 --->__CaO + __CO2 2 1 Answer CaCO3 CaO + CO2

  11. DIRECTIONS: Copy these equations on the paper you will be turning in. Balance each equation on your own. 1. __H2 + __Cl2---> __HCl __Na+ __F2 ---> __NaF 2. __H2O2 ---> __H2O + __O2 3. __KClO3 --->__KCl+ __O2 4. __P+ __O2---> __P4O10 5.

  12. 12/21/2011 Standards: 3(Stoichiometry & Conservation of Matter) Objectives: a. Practice Balancing Equations DO NOW: 1. Balance these 3 equations: a. C2H5OH (l) + O2 (g)à CO2 (g) + H2O (g) b. NH3(g) + O2 (g)à NO (g) + H2O (g) c. SiO2 (S) + HF (aq)à SiF4 (g) + H2O (l) HOMEWORK: 1. Have a Merry Christmas and a Happy New Year!!!
