Presentation Transcript

  1. Warm up How would you define a double replacement reaction?

  2. Warm up answers A chemical reaction in which the ions of the reactants switch partners to form products

  3. TEST TESTTESTTESTTESTTESTTEST This experiment will be graded as a test grade, therefore it is worth a larger percentage of your grade than the other experiments we have done so far. Adjust your effort accordingly if you need to.

  4. question What are the products of the following reactions? A. Sodium Carbonate with Silver Nitrate B. Sodium Carbonate with Lead Nitrate C. Sodium Carbonate with Calcium Chloride

  5. hypothesis Learn a little about each chemical before you make a hypothesis

  6. Background information Sodium Carbonate http://en.wikipedia.org/wiki/Sodium_carbonate Lead Nitrate http://en.wikipedia.org/wiki/Lead(II)_nitrate Silver Nitrate http://en.wikipedia.org/wiki/AgNO3 Calcium Chloride http://en.wikipedia.org/wiki/Calcium_chloride Now make your hypotheses (plural of hypothesis)

  7. methods Mix the chemicals together

  8. results Record your observations in a data table. Draw a picture (or use a photo), and write a description

  9. conclusion A. 2 AgNO3 + Na2CO3 ?? + ?? B. Pb(NO3)2 + Na2CO3?? + ?? C. CaCl2+ Na2CO3?? + ??

  10. Cool down Go through your notebook and make sure you have notes for every experiment we have done so far What is a creative way you could apply what you learned in class today?
