Specific Expectations for Academic grade 11 Chemistry: Chemical Reactions
 Write balanced chemical equations to represent synthesis, decomposition, single
displacement, double displacement, and combustion reactions using the IUPAC
nomenclature system
Materials needed:
 Demo: piece of magnesium metal, Bunsen burner, flint, safety goggles, tongs
 Class activity: handout with chemical reaction problems
Time sequence:
 Approximately 1 minute to go over learning goal and agenda
 Approximately 5 minutes for Demo and related discussion
 Approximately 4 minutes to review reaction patterns, polyatomic ions, and balancing
equations
 Approximately 5 minutes to teach predicting products of chemical reactions
 Approximately 5 minutes for take-up of class activity
Introduction
 Today’s lesson will be on predicting the products of chemical reactions
 The learning goal for today’s lesson is to predict the products of synthesis,
decomposition, single displacement, and double displacement, and combustion
reactions and write balanced chemical equations for the reaction
 Here is the agenda for today: 1) Demo 2) Review of reaction patterns, polyatomic ions,
and balancing equations 3) Lesson on predicting products of chemical reactions 4)
Activity take-up
 We will start the class with the demo: magnesium combustion
Key questions:
 Demo:
1. What type of reaction do you expect to see when something is burned?
(expected answer: combustion)
2. What are the starting reagents? (expected answer: magnesium metal, oxygen)
3. What might the product be? (expected answer: MgO)
 Review:
1. What are the four types of reactions you learned last year?
2. When writing out a complete reaction, what must we do to preserve
mass/molecule composition on both the reagent and product sides? (expected
answer: balance)
3. Are the elements in a polyatomic ion separable?
 Lesson:
1. Can you predict the product of this reaction based on the patterns we
discussed?
vi)
vii)
2. What could be the first step in helping you predict the product of a reaction?
(expected answer: finding the pattern)
3. What type of reaction could a combustion reaction be? (expected answer:
synthesis – related to the demo)
Concluding Idea/Summary
 Keep in mind: make sure equations are balanced, consider that the elements in
polyatomic ions are all one entity
 If a particular reaction appears difficult, start off by identifying the pattern
 Expectations: be able to predict products and write balanced chemical equations to
represent synthesis, decomposition, single displacement, double displacement, and
combustion reactions for quizzes, tests, assignments
