Types of Chemical Reactions

 

COMBINATION (Synthesis) REACTION  A reaction when 2 or more more reactants combine to form a singe !ro"#ct$ The genera form#a for this reaction is %

 

&ECOM'OSITION REACTION &ECOM'OSITION In this reaction a singe reactant breas "own into sim!er ones$ (2 or more !ro"#cts)$ This is the re*erse of combination reaction$ The genera form#a for this reaction is%

 

SIN+,E &IS',ACEMENT (Re!acement) REACTION% This is when one eement re!aces another eement from a com!o#n"$ The more acti*e eement taes the !ace of the ess acti*e eement in a com!o#n"$ The genera form#a for this reaction is%

 

&O-B,E &IS',ACEMENT REACTION (Metathesis) This is when the !ositi*e ions (cations) an" negati*e ions (anions) of "ifferent com!o#n"s switch !aces forming two entirey "ifferent com!o#n"s$ The genera form#a for this reaction is%

 

COMB-STION (B#rning) REACTION This is when o.ygen combines with a hy"rocarbon (com!o#n" containing hy"rogen an" carbon) to form a water an" carbon "io.i"e$

 

 ACI&/BASE REAC REACTION TION This is a s!ecia in" of "o#be "is!acement reaction that taes !ace "is!acement when an aci" an" base react with each other$ The 01 of the aci" reacts with the O0/ of the base forming water$ The other !ro"#ct is sat$
