Chemical Reactions

15 May Chemical Reactions

A process leading to the transformation or change of one set of chemical substances to another. It is a method in which the reactants are converted to products. Substances are either chemical elements or compounds. In simpler words, chemistry tuition explains chemical reactions as the rearrangement of atoms of the reactants to create different substances as products. Chemical reactions have become an important aspect of technology and culture. For thousands of years chemical reactions have known to be or used in burning fuels, smelting iron, making glass and pottery and inhibited in the process of making wine and cheese. Chemical reactions have become a part of our daily lives. Chemical reactions occur in the geography of earth, in the atmosphere, oceans and in the vast area of complicated processes that occur in all living beings. The most common types of chemical reactions are:

  • Combination Reaction: Two or more reactants form a single product. For example: 2Na + Cl2 = NaCl2.
  • Decomposition Reaction: The opposite of composition reaction. It is a single compound breaking down into two or more simpler substances. An example is the decomposition of water into hydrogen and oxygen gases: 2H2O: 2 H2 + O2.
  • Double Displacement: In single displacement reaction, only one element is displaced. In double displacement two species (normally ions) are displaced. This is also known as metathesis reactions.
  • Combustion Reactions: The combination of a compound containing carbon, combines with the oxygen gas in the car. The process is termed as burning. Heat is the most precise product of most combustion reactions.
  • Redox Reactions: Known as reduction- oxidation reactions are reactions wherein electrons are exchanged. For example: 2Na + Cl2 = 2NaCl or C + O2= CO2
