catalyst
Catalyst
  • Please take out your homework.
  • Answer the following question on your catalyst:
objective
Objective
  • I can describe chemical reactions by balancing chemical equations.
  • I can identify different types of reactions and predict the products of reactions.
agenda
Agenda
  • Catalyst
  • Video Investigation: Cu (s) + AgNO3 (aq) ??
  • Interactive Notes & Practice: Chemical Reactions
notes video investigation
Notes: Video Investigation
  • Reaction: http://www.youtube.com/watch?v=Sn1dkafX9As&feature=fvwrel
    • Cu (s) + 2 AgNO3(aq)  ??
  • Focus Questions:
    • What do you see happening?
    • What do you think the products are?
    • How could you test whether your prediction is correct?
think pair share vocabulary review
Think, Pair, Share: Vocabulary Review
  • Think: Match the types of reactions with their definitions. Put a star next to the reaction type that you think you saw in the video.
  • Pair: Share your answers with your neighbor. Compare answers. Do you agree or disagree?
  • Share: At least 5 people will share.
vocabular y review answers
Vocabulary Review Answers
  • Synthesis
    • Two or more reactants are put together to form a single compound.
  • Decomposition
    • A single compound breaks down into two or more elements or simpler compounds.
  • Combustion
    • The reaction of a carbon-based compound with oxygen.
  • Single Replacement
    • A single uncombined element replaces another in a compound.
  • Double Replacement
    • Parts of two compounds switch places to form two new compounds.

    • http://www.youtube.com/watch?v=OBdgeJFzSec
    • __ Mg(s) + __HCl (aq)  __ H2 (g) + __ MgCl2 (s)
  • Describe what you see in the space on your worksheet.
  • Then, balance the equation.
part 4 the activity series
Part 4: The activity series
  • Turn to page 832 of your textbook!
  • The results of replacement reactions are summarized in the activity series.
  • Elements are listed from the most active on the top to the least active on the bottom.
  • A more active element will replace those listed below it in a single replacement reaction. We can use the activity series to predict whether a reaction will occur.
  • TPS: Where are metals on the activity series? Where are nonmetals? What other patterns do you see?
activity series example
Activity Series Example
  • Locate copper (Cu) and silver (Ag) on the activity series.
  • Which is more active? Will the following reaction occur?
  • Cu (s) + 2 AgNO3 (aq)  ??
  • Answer: Yes! Copper is more active. It replaces silver.
  • Cu (s) + 2 AgNO3 (aq) 2 Ag (s) + Cu(NO3)2 (aq)
  • Think Box: Answer the think box question on your worksheet.
practice thumbs up down
Practice: Thumbs Up/Down
  • Will Calcium (Ca) replace Magnesium (Mg)?
    • Yes – calcium is higher on the activity series.
  • Will Lead (Pb) replace Calcium (Ca)?
    • No – lead is lower on the activity series.
  • Will Zinc (Zn) replace Nickel (Ni)?
    • Yes – zinc is higher on the activity series.
partner practice
Partner Practice
  • Work with your partner to complete the rest of the worksheet.
  • Raise your hand when you are done to get a stamp.
  • Answers are posted on the board.
homework
Homework
