Another Cheesy Chemistry Music
Video…
• http://www.youtube.com/watch?v=QjVYz00Kxc&feature=channel&list=UL
• 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=rWCvymhpfY&feature=channel&list=UL
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
