Presentation transcript:

Clicker #1 Balance the following equation and determine the sum of the coefficients: C2H5OH + O2 → CO2 + H2O A) 4 B) 5 C) 8 D) 9 E) 10 This is a quick way for us to see if you balanced the equation correctly.

Clicker #2 What are the possible products? AgNO3(aq) + KCl(aq) → ? A) AgCl and KNO3 B) AgNO3 and KCl C) AgK and NO3Cl D) Any of the above could be the products.

Clicker #3 So what is true about KNO3? A) KNO3 is aqueous (soluble) in all three reactions. B) KNO3 is the solid in reactions 1 and 2 but not reaction 3. C) KNO3 is the solid in reaction 1 but not in reactions 2 and 3. D) KNO3 is the solid in reaction 2 but not in reactions 1 and 3 E) KNO3 is the solid in reaction 3 but not in reactions 1 and 2.

Precipitation Reactions Know how to use the solubility rules (you will be given them on the exam). Know how to write equations from reactants (ionic reactants). Understand what solutions “look” like at a very magnified level.
