No Drill – Drill Quiz n Take out a sheet of notebook paper and your drills. For each date listed, write the question AND the answer. You have 10 minutes. n 1/29, n HW: 2/3, 2/9 pg. 14 Types of Reactions (and balancing)

Objectives n IWBAT n n n Translate a verbal description of a chemical reaction into a formula equation, showing states Balance chemical equations by adjusting coefficients Identify the five types of chemical reaction

Quiz Discussion n Let’s n n take a look at two quizzes Organic Chem Quiz Translating/Balancing Quiz n. I am going to do a Re-Do session on Monday for the Translating/Balancing Quiz. If you come, you may take a NEW quiz on Tuesday, after school, or before school by Tuesday. n n If you can’t come to the Monday Re-Do session, you MUST come before school two days for help. You MUST let me know that you’re interested by Thursday!!!!

Types of Reactions Research n You have been assigned a type of chemical reaction. You have done research to define and get important information about that reaction. n Next, you will meet with a group and share your information. n Then, your group will come up with an analogy to explain the different types of reactions.

Types of Reactions – Analogies n Your group will come up with an analogy to explain the different types of reactions. n Let’s share some!

Types of Reactions Assessment

A + B AB

Synthesis

A free element reacts with a compound to form a new compound and to release one of the elements of the original compound

Single Replacement (Single Displacement)

3 Ca. Cl 2 + 2 Al. N 2 Al. Cl 3 + Ca 3 N 2

Double Replacement (Double Displacement)

2 KI + Cl 2 2 KCl + I 2

Single Replacement

Synthesis

Two ionic compounds react to form two new ionic compounds; “switching partners” AB + CD AC + BD

Double Replacement (Double Displacement)

AB + C AC + B

Single Replacement

n ONE compound breaks down into simpler substances n General Equation: AB A + B

Decomposition

Types of Reactions Practice n pg. 14 – Types of Reactions n Using your notes, balance the equation and then predict the type of reaction that the equation represents.
