Different Kinds of Chemical Reactions

There are many chemical reactions that take place between chemicals and their reactants, most of them occuring inside our body without us realizing it. These reactions include synthesis, decomposition, single-replacement, double replacement, and combustion.

Synthesis is a chemical reaction in which it is purposely made to react with another chemical or chemicals. it is also physically or chemically manipulated. This usually means that the reaction is reproducible and reliable.

Another type of reaction is known as chemical decomposition. This involves the seperation of chemical compounds, and, in turn, breaking the compound down to simpler elements or compounds. These type of reactions are usually undesired.

Single-replacement reactions are yet another type of reaction. This type of reaction is also known as an oxidation-reduction chemical reaction. This is when an element or ion moves from one compund to another. the elements usually replace each other in their respective compounds.

Another similar reaction to the single- replacement reaction is called the double-replacement reaction. It is also called the metathesis reaction. Instead of exchanging single elements, like the single-replacement reaction, this involves the exchange of bonds resulting in chemical species with similar bonding affiliations.

The last form of reaction is called combustion. This, no doubt, involves heat. It is a series of exothermic reactions with fuel and its oxidant accompanied by heat. This heat usually causes glowing or flames. Many fuels often include hydrocarbons.

These reactions provide the basis of what created life and helped to create the world we know today.
