Journal Entry:
What is a catalyst? How does a catalyst affect a chemical reaction?

Learning Intentions

• We will learn what a catalyst is and how they work in chemical reactions.
• We will learn how to write and balance chemical equations.
• We will learn how to identify patterns in chemical equations that reflect different types of reactions.
• We will learn how to classify chemical equations as representing combination, decomposition, single exchange, or double exchange reactions.

Closing Task:

 You can review concepts from this chapter to prepare for our formative assessment.

Content Standards being covered:

Student understands what the letters and numbers stand for in a compound formula, can use those letter and numbers to determine how many of each type of element there are in a formula.

Student can create mathematical representations of chemical reactions and use them to make calculations about products and reactants.

Students can use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction. (HS-PS1-7 and CCC Energy and Matter)
