dedine chemical reaction and write the name of five type of chemical reaction?
A chemical reaction is a process that involves a chemical change in which the starting materials (reactants) are different from the products. They also involve the motion of electrons, leading to the formation and breaking of chemical bonds.
1) Direct Combination or Synthesis Reaction In a synthesis reaction two or more reactants form a more complex product.
A + B → AB & 2) Chemical Decomposition or Analysis Reaction In a decomposition reaction a compound is broken into smaller chemical species.
AB → A + B
3) Single Displacement or Substitution Reaction In single displacement reaction one element has being displaced from a compound by another element.
A + BC → AC + B
4) Metathesis or Double Displacement Reaction In a double displacement or metathesis reaction two compounds exchange bonds or ions in order to form different compounds.
AB + CD → AD + CB
5) Oxidation-Reduction or Redox Reaction In a redox reaction the oxidation numbers of atoms are changed. Redox reactions may involve the transfer of electrons between chemical species.
