Types of Chemical Reactions

Types of Chemical Reactions 1. 2. 3. 4. 5. 6. Synthesis reactions Decomposition reactions Single displacement reactions Double displacement reactions Combustion reactions Redox Reactions According to your Performance Standards, you need to be able to identify each type. Let us first understand each type of reactions

Reaction AB + CD → AB + CD

Combustion Reaction Redox Reaction The burning of carbon or carbon compounds to give carbon dioxide and water. Note: You will get only carbon dioxide when carbon burns; No water will be formed. C(s) + O 2 (g) → CO 2(g) CH 4(g) + O 2(g) → CO 2(g) + H 2 O(l) Reaction between two cations The ion with higher charge becomes an ion with smaller charge (Reduction); the ion with smaller charge becomes an ion with higher charge (Oxidation) (Overall reaction)

Identify the Types of Chemical Reaction in each of the following Balance the reactions 1 to 6 and indicate which type of chemical reaction (synthesis, decomposition, singledisplacement, double-displacement or combustion) is being represented: 1. ____ Na. Br + ____ Ca(OH)2 ___ Ca. Br 2 + ____ Na. OH Reaction Type : _______ 1. ____ NH 3+ ____ H 2 SO 4 ____ (NH 4)2 SO 4 Reaction Type : _______ 1. ____ C 5 H 9 O + ____ O 2 ____ CO 2 + ____ H 2 O Reaction Type : _______ 1. ____ Pb + ____ H 3 PO 4 ____ H 2 + ____ Pb 3(PO 4)2 Reaction Type : _______ 1. ____ Li 3 N + ____ NH 4 NO 3 ___ Li. NO 3 + ___ (NH 4)3 N Reaction Type : _______ 1. ____ HBr + ___ Al(OH)3 ___ H 2 O + ___ Al. Br 3 Reaction Type : _______
