Types of Chemical Reaction

• Combination (Synthesis) Reaction is when 2 or more reactants combine to form a single product.

  A+B=AB
• Decomposition Reaction is when a single reactant breaks down into simpler ones.

  AB=A+B
• Single Displacement (Replacement) Reaction is when one element replaces another element from a compound.

  A+BC=AC+B
• Double Displacement (Replacement) Reaction (Metathesis) is when positive ions (cations) and negative ions (anions) of different compounds switch places, forming 2 entirely different compounds.

  AB+CD=AD+BC
• Combustion (Burning) Reaction is when oxygen combines with a hydrocarbon to form carbon dioxide and water.

  C4H10+O2=CO2+H2O
• Acid-base reaction is when acid and base react with each other. The H+ of the acid reacts with OH- of the base forming water. The other product is salt.

  HCl+NaOH=NaCl+H2O
