Objectives 5.9, 5.10, 5.11, 5.12

SUMMARY OF REACTION TYPES LEARNED Synthesis reaction - Two or more substances combine to form a new compound

Example: A + B AB Decomposition reaction - A single compound undergoes a reaction that produces two or more simpler substances

Example: AB A + B or ABC AB + C Single Displacement reaction - One element replaces or “displaces” another element in a compound

Example: A + BC AC + B Remember – Element can only displace another element BELOW itself on the activity series chart!

Double Displacement reaction - Ions of two compounds exchange places to form two new compounds Example: AB + CD AD + CB

Combustion reaction - Substance combines with oxygen, and releases energy in the form of light and heat. Example: CxHx + O2 (g) CO2 (g) + H2O (l)

Goal: You’re goal today is to work in groups and to use each other, class notes, and the guided PowerPoint as resources to be able to predict products for synthesis, decomposition, single displacement, double displacement and combustion reactions.

Method: Based on class discussions, you will attempt to predict products based upon the reaction type determined. For any struggles/clarifications you might need, please refer to the narrated PowerPoint slides for guidance and examples.

Objective: Every student will be able to correctly predict products, write correct formulas, and balance equations for each of the types of chemical reactions. Please see reverse side for assignment to be turned in. ALL STUDENTS MUST BE WORKING TOGETHER ON THE SAME REACTION TYPE. There will be no dividing up questions amongst the group.

Use the following websites for guided examples for each of the following reaction types:

FOR EACH OF THE FOLLOWING EQUATIONS, identify the reaction type, predict the products (making sure to NEVER carry subscripts unless part of a polyatomic ion), write correct formulas of products (using charges of elements in new compounds formed) and balance the equation. For single displacement and double displacement reactions, make sure to determine if a reaction will take place (SD – activity series chart, DD – solubility chart).
