*Determine if a chemical reaction is a Redox reaction or not
*Using appropriate drawings and explanation, determine which specie will be oxidized & reduced
*Using appropriate drawings and explanation, determine which reactants (whole species) will be the reducing agent & oxidizing agent.

*Determine if a chemical reaction is a Redox reaction or not(11.1 & 11.2)
*Using appropriate drawings and explanation, determine which specie will be oxidized & reduced (11.1 & 11.2)
*Using appropriate drawings and explanation, determine which reactants (whole species) will be the reducing agent & oxidizing agent. (11.1 & 11.2)

Limiting Reactant
Broad Concept(MCAS Framework): The conservation of atoms in chemical reactions leads to the ability to calculate the mass of products and reactants (5.Chemical Reactions and Stoichiometry)

Essential Question: Do you have enough pieces of bologna for your bologna sandwiches for the Super Bowl (Go Patriots)

Each student will be able to:

Determine if a questions is limiting reactant problem or not.(5.5)
Determine/calculate which reactant is limiting (and therefore in excess).(5.5)
Determine the amount of product(s) produced in the rxn .(5.5)
Determine the amount of excess reactant material .(5.5)

Determine the actual yield, theoretical yield, and percent yield of product(s)..(5.6)

Redox (Oxidation-Reduction) Reactions

Broad Concept(MCAS Framework): Oxidation-reduction reactions occur by electron transfer and constitute a major class of chemical reaction.(11.Oxidation-Reduction and Electrochemistry)

Essential Question: Follow the bouncing electron to show who is doing work. (LEOthe lion goes GER)

Each student will be able to:

Determine if a chemical reaction is a Redox reaction or not(11.1 & 11.2)
Using appropriate drawings and explanation, determine which specie will be oxidized & reduced (11.1 & 11.2)
Using appropriate drawings and explanation, determine which reactants (whole species) will be the reducing agent & oxidizing agent. (11.1 & 11.2)

WILL NOT REQUIRE STUDENTS TO KNOW HOW TO BALANCE REDOX REACTIONS
