ESSENTIAL QUESTION: What is percent yield?
RELEVANCE: How can we determine how much product is produced in a reaction?
NGSSS: SC.912.P.8.9; MAFS.912.N-Q.1.1; LAFS.910.L.3.4.d; LAFS.910.W.1.1
LEARNING OBJECTIVES: Students will be able to:
-apply the mole concept and the law of conservation of mass to calculate quantities of chemicals participating in reactions.
BELL RINGER: Kahoot.it - Balancing Chemical Equations
VOCABULARY: atomic mass unit, Avogadro’s number, molecular formula, molar mass, percent yield
HOME LEARNING: HL 1 Percent Yield
AGENDA
WHOLE GROUP
Our bell ringer was a Kahoot.it on balancing chemical equations.
Classes then completed the GIZMO on Limiting Reagents.
We took notes (be sure to place the date, benchmark, and Essential Question in the table of contents; then make a Cornell notes page with page number, date and Essential Question). Leave the interior of the notes blank. Take notes on the NEXT page. You are to record all that is written in red. You can find a movie of the notes below. To see the actual powerpoint, you can click the link Limiting Reagents and Percent Yield.
Video of the notes on Limiting Reagents and Percent Yield
We also worked through several example problems.
Be prepared to take a quiz on these types of problems next week!
Home learning was distributed, but I did not get a chance to scan it into the computer, so be sure to pick up a copy. Remember, it MUST be included in your interactive notebook!
SMALL GROUP/INDEPENDENT PRACTICE/DI
Students who compete work early should go to
Khan Academy - chemical reactions and stoichiometry - balancing chemical reactions
HOTS:
-How does balancing chemical equations relate to conservation of matter?
-While balancing a chemical equation, why are you allowed to change the coefficients but not the subscripts?
EXIT STRATEGY: - summarize notes
