Types of Reactions

5 Types of Reactions Combustion Synthesis Decomposition Single Displacement Double Displacement

Combustion Oxidation reduction of an organic compound where heat is released Organic compound reacts with oxygen to make carbon dioxide and water CH4 + 2O2 → CO2 + 2H2O

Synthesis Two or more substances react to form a new compound 2 or more reactants and only 1 product 2C + O2 → 2CO CO2 + H2O → H2CO3

Decomposition Single compound breaks down to form 2 or more simpler compounds 1 reactant more than 1 product 2H2O → 2H2 + O2 CaCO3 → CO2 + CaO

Single Displacement Single element reacts with a compound and takes the place of one of the elements in the compound Element and a compound form an element and a compound 2Al(s) + 3CuCl2(aq) → 2AlCl3(aq) + 3Cu(s)

Double Displacement Gas, solid precipitate, or a molecular compound forms from the apparent exchange of atoms or ions between two compounds 2 compound make 2 different compounds 2KI(aq) + Pb(NO3)2(aq)→ PbI2(s) + 2KNO3(aq)
