Synthesis


    A synthesis reaction is a type of reaction in which multiple reactants combine to form a single product. Synthesis reactions release energy in the form of heat and light, so they are exothermic. An example of a synthesis reaction is the formation of water from hydrogen and oxygen. Equation A + B - AB


Decomposition


    A decomposition reaction is a type of chemical reaction in which a single compound breaks down into two or more elements or new compounds. These reactions often involve an energy source such as heat, light, or electricity that breaks apart the bonds of compounds. Equation AB - A + B


Single Replacement


    A single-displacement reaction, also named single-replacement reaction, is a type of oxidation-reduction chemical reaction when an element or ion moves out of one compound and into another - that is, one element is replaced by another in a compound. Equation AX + Y ---> YX + A


Double Replacement

A double displacement reaction, also known as a double replacement reaction or metathesis reaction, is a type of reaction that occurs when the cations and anions switch between two reactants to form new products. Equation AB + XY ---> AY + XB

Combustion


    A combustion reaction is a reaction in which one of the reactants is oxygen. ▪ The other reactant is usually a hydrocarbon. Equation CxHy + O2 ---> CO2 + H2O
