Chemical Reactions Combination or Synthesis Reaction

Single Replacement Reaction

Decomposition Reaction

Double Replacement Reaction

Combination or Synthesis Reaction • A synthesis reaction is when there is a combination of two or more substances and a compound results. An example of a  A synthesis +B AB reaction is as follows:

Decomposition Reaction • Decomposition is the opposite of synthesis. It is when a compound is broken down into simpler substances, usually through electrolysis. An example of ABdecomposition  A + B is as follows: 

Single Replacement Reaction In a single

replacement reaction, there is a rule that is always followed. A metal replaces a metal, or a nonmetal replaces a nonmetal. An of a + B ABexample + C  AC single replacement reaction is as follows:

•

Double Replacement Reaction In a double

replacement reaction, this rule is always followed. A metal replaces a metal, and a nonmetal replaces a nonmetal. An example of a double replacement AB+XY AY+ XB reaction is as follows:
