1. Chem Catalyst How can you tell if a reaction is: - a single replacement reaction? - a decomposition reaction? - a combustion reaction? - a combination reaction? - a double replacement reaction?

2. Today’s Agenda: 1. Catalyst 2. Quiz 3. Notes: Predicting products 4. HW: p. 339 #26

3. Predicting Products: - Combination: - Form the ionic compound that results from the two elements - Ex: Write the equation for the reaction of solid Be and oxygen gas

4. Predicting Products: - Decomposition: - Separate the elements - Ex: Write the equation for the decomposition of HI

5. Predicting Products: - Single-Replacement: - A metal will replace a less active metal in the ionic compound - Ex: Write the equation for the reaction of solid iron and aqueous lead (II) nitrate

6. Predicting Products: - Double-Replacement: - Separate the ionic compounds and trade cations to write new ionic compounds - Ex: Write the equation for the reaction of NaOH and Fe(NO 3 ) 3
