Top 10 Ways for Balancing of Chemical Reactions and Types of Chemical Reaction

Balancing of Chemical Reactions

                                                    For balancing of chemical reaction the no. of atom on reactant side should be equal to no. of atom on product side, so that total mass of reactant is equal to total mass of product. You read these 9 class notes at www.ChemistryNotesInfo.com of ‘Chemistry Notes Info’ organization website.
H2 + O2   ----->   H2O   (Imbalance Equation)
2H2 + O2 ----->   2H2O   (Balance Equation)

Types of Chemical Reaction

  • ·        Addition Reaction

  • ·        Decomposition Reaction

  • ·        Substitution Reaction

  • ·        Oxidation and Reduction Reaction

1.     Addition Reaction

Reactions in which two or more than two substances reacts together to produce a new compound is known as Addition Reaction.
Example:-
2Mg + O2 ------> 2MgO

          2.     Decomposition Reaction

Reactions in which one compound get break into two or more than two simple compounds by breaking of chemical bonds, these chemical bonds get broken by heat, light or electricity.
Example:-
CaCO3 ------> CaO + CO2

          3.     Substitution Reaction

Reactions in which one element replaces another element to form a new compound is known as Substitution Reaction
Example:-
CuSO4 (Aq) + Zn (s) -----> ZnSO4 (Aq) + Cu (s)

          4.     Oxidation and Reduction Reaction

Oxidation and reduction reaction are described below on these two basis-
          Oxidation and Reduction Reaction based on oxygen and hydrogen-
·  Removal of hydrogen and addition of oxygen is known as oxidation reaction.
·  Removal of oxygen and addition of hydrogen is known as reduction reaction.
Oxidation and Reduction Reaction based on electron transfer-
·        Oxidation reactions are the reactions in which atom or ion looses electrons.
·         Reduction reactions are the reactions in which atom or ion gains electrons.
Oxidation and Reduction reactions occurs simultaneously because electron removed from one atom or radical is added to another atom or radical.
