Journal Entry:

Consider this chemical reaction: AgNO₃(aq) + KCl(aq) -->KNO₃(aq) +AgCl(s)

a. What do you expect to observe if you carry out this reaction in a laboratory?

b. Write an interpretation of the chemical equation, describing what is taking place.

Learning Intentions

• We will  learn how to relate chemical equations to real world observations

• We will learn how to make predictions based on chemical equations.

Closing Task:

 You can examine a chemical equation and describe what is taking place.

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)
