week 21 

if  not done & weather permits:

Objective: electrolyze water and use hydrogen fuel cell; write equations for reactions;

lesson: sunny day.. electrolysis outside with hydrogen fuel cell kit; go over hw problems; start activity series if time; start HCl and penny start

hw fuel cell sketch and form

 mon

no school presidents day 

tue

objective: calculate theoretical yield, actual (experimental)yield, and  % yield; stoichiometric calculations

lesson:  discuss lab;    finish correcting hw problems;  demo methanol pop; calculate water from starting amount of methanol.  get final measurement from oven. 

hw ch9 bs lab  - finish calculations for 3 trials (with my data as trial 2) &  answer conclusions,& submit form  

wed

Objective:   Use stoichiometry to calculate % yield; molar volume of gases; gas stoichiometry

lesson: finish bs lab  chapter 9 notes stoich; notes actual, theoretical, and % yield; limiting and excess reactants

Lesson:  do   mgo lab  ; go over hw problems;  

Lesson: go over text problems, then magnesium oxide video of burning  g. et mgo lab data in class; if you are absent, use this data:  crucible= 75.50g  crucible & Mg= 75.95g  crucible and MgO= 76.10g. 

hw   mgo lab.  calculations, conclusions, and form

thur no class

friday

Objective:  calculate amounts of reactants and products using stochiometry; calculate % yield;  molar volume of gases

lesson: discuss MgO lab    discuss propane demo & example if time permits; 

Lesson: Don't understand stochiometry?  maybe this guy can help. Don't understand stochiometry? how to to do stochiometry   

   why the bottles? Hint: molar volume of gases

hw  all types stoch interactive  (do all 18 !! show da on paper)
