                                     and do mole and mass
   soda?                             conversions.

• Focus question: What is the law of conservation
  of mass and what does it have to do with
  balancing chemical equations?

• As you watch the video, jot down your thoughts
  on the focus question under your catalyst. Then,
  be ready to share.
Chemical Reactions Study Guide
• Why? This study guide reviews and practices the
  skills necessary for success in our next unit –
  Stoichiometry!
• Instructions:
• Work quietly with the person next to you.
• Show all your work on a separate sheet of paper.
• Answers are posted at the front of the room.
• When you complete a section (reach a stop sign),
  get up, check your answers, correct any mistakes,
  and get a stamp.
• Do we need a break? http://www.youtube.com/watch?v=rWCv-

If you finish your study guide…
• Choose 1 of the following options:
 ▫ Continue working on your balancing equations
   race worksheet.
 ▫ Pick an article from the back counter that you
   have not read yet. Read and complete the reading
   questions.
 ▫ Start HW: p. 295 #50 & 53, p. 251 #12, 14, 15, p.
   252 #33 & 39

1. What is the molar mass of NH3?
2. What is the mass (in grams) of 3 moles NH3 ?
3. I have 34g NH3. How many moles NH3 do I
   have?
4. Balance the following chemical reaction
   equation:
    __ NH3 +__ CuO → __ Cu +_ N2 + _H2O
