Unit+1+classifying+reactions

A chemical reaction is described in the general form of reactions ---> products. The reactants are always on the left hand side and the products are always on the left hand side. The reactions and products will always be seperated by an arrow. __**Word Equations:**__ A word equation uses words instead of symbols to explain the reaction process. Ex: Methane (CH 4 ) is combusted in oxygen to form carbon dioxide and water. = CH 4 + O 2 ---> CO 2 + H 2 O Note: The word "form" will show which chemicals are reactants and which are products.
 * __Classifying Reactions__ **

** __Reaction Types:__ ** The following are gneral forms of what the five reaction types would look like without using chemical symbols. Combustion: When any chemical substance reacts with oxygen Single Replacement: Double Replacement: Synthesis: Decompostion:
 * A + O 2 ---> AxOx
 * A + BX ---> B + AX
 * AX + BY ---> AY + BX
 * A + B ---> AB
 * AB ---> A + B


 * __Acid and Base Reactions__ **
 * __Acid__: a compound that donates a hydrogen ion (H+).
 * __Base__: a compound that accepts hydrogen ions.

** __General Form:__ ** This process of a base and and acid reacting together is called //**neutralization**//.
 * Acid + Base ---> Salt + Water
 * or HY + XOH ---> XY + H2O
