REACTIONS

Several general types of chemical reactions can occur based on what happens when going from reactants to products. The more common types of chemical reactions are as follows:

Combination

Decomposition

Single displacement

Double displacement

Combustion

Redox

COMBINATION CHEMICAL REACTIONS

Incombination reactions, two or more reactants form one product. The reaction of sodium and chlorine to form sodium chloride,



and the burning of coal (carbon) to give carbon dioxide,



are examples of combination reactions.

COMBINATION CHEMICAL REACTIONS

Incombination reactions, two or more reactants form one product. The reaction of sodium and chlorine to form sodium chloride,



and the burning of coal (carbon) to give carbon dioxide,



are examples of combination reactions.

DECOMPOSITION CHEMICAL REACTIONS

Decomposition reactions are really the opposite of combination reactions. Indecomposition reactions, a single compound breaks down into two or more simpler substances (elements and/or compounds).

The decomposition of water into hydrogen and oxygen gases,



and the decomposition of hydrogen peroxide to form oxygen gas and water,



are examples of decomposition reactions.

SINGLE DISPLACEMENT CHEMICAL REACTIONS

Insingle displacement reactions, a more active element displaces (kicks out) another less active element from a compound. For example, if you put a piece of zinc metal into a copper(II) sulfate solution, the zinc displaces the copper, as shown in this equation:



The notation(aq)indicates that the compound is dissolved in water — in anaqueous solution. Because zinc replaces copper in this case, it’s said to be more active. If you place a piece of copper in a zinc sulfate solution, nothing will happen.
