Types of Reactions and Predicting Products SNC 2 D

Types of Reactions can be divided into 4 main types: n Synthesis n Decomposition

Types of Reactions can be divided into 4 main types: n Synthesis n Decomposition n Single Displacement/Replacement n Double Displacement/Replacement

Synthesis: 2 or more reactants combine to form 1 product

Synthesis: 2 or more reactants combine to form 1 product

Synthesis: 2 or more reactants combine to form 1 product

Synthesis: 2 or more reactants combine to form 1 product

Synthesis: 2 or more reactants combine to form 1 product e. g. Mg +

Synthesis: 2 or more reactants combine to form 1 product e. g. Mg + O 2 -> Mg. O

Synthesis: 2 or more reactants combine to form 1 product e. g. 2 Mg

Single Displacement: a single element replaces another in a compound

Single Displacement: a single element replaces another in a compound

Single Displacement: a single element replaces another in a compound e. g. Mg. Br

Single Displacement: a single element replaces another in a compound e. g. Mg. Br 2 + Cl 2 Mg. Cl 2 + Br 2 Negative ions replace negative ions!

Single Displacement: a single element replaces another in a compound e. g. Fe +

Single Displacement: a single element replaces another in a compound e. g. Fe + Cu. SO 4

Single Displacement: a single element replaces another in a compound e. g. Fe +

Single Displacement: a single element replaces another in a compound e. g. Fe + Cu. SO 4 Cu + Fe. SO 4 And positive ions replace positive ions!

Double Displacement: parts of two compounds switch places

Double Displacement: parts of two compounds switch places

Double Displacement: parts of two compounds switch places e. g. Na. OH + Fe.

Double Displacement: parts of two compounds switch places e. g. Na. OH + Fe. Cl 3

Double Displacement: parts of two compounds switch places e. g. Na. OH + Fe.

Double Displacement: parts of two compounds switch places e. g. Na. OH + Fe. Cl 3 Fe(OH)3 + Na. Cl

Double Displacement: parts of two compounds switch places e. g. 3 Na. OH +

Double Displacement: parts of two compounds switch places e. g. 3 Na. OH + Fe. Cl 3 Fe(OH)3 + 3 Na. Cl

Double Displacement: parts of two compounds switch places e. g. 3 Na. OH +

Double Displacement: parts of two compounds switch places e. g. 3 Na. OH + Fe. Cl 3 Fe(OH)3 + 3 Na. Cl Remember that positive ions pair with negative ions.

Combustion And remember that there also exist combustion reactions: e. g. the combustion of

Combustion And remember that there also exist combustion reactions: e. g. the combustion of hydrocarbons like methane CH 4 + O 2 CO 2 + H 2 O
