Question

define types of reaction with their example and also balance those equation​

Answer 1

Answer:

There are 9  types of chemical reactions.

Explanation:

a.  combination reaction- a reaction in which a single product is formed from two or more reactants is known as a combination reaction. E.g,  CaO+H2O= Ca(OH)2+heat.

b. Endothermic reaction- a reaction in which external heat is taken during the reaction is known as endothermic reaction.E.g,  photosynthesis.

c. Exothermic reaction-  a reaction in which heat is liberated out is called exothermic reactions. E.g,  CH4+2O2= CO2+2H2O.

d. Decomposition reaction- a type of reaction in which one compound breaks into two or more compounds when heat,electricity,light is given on it. E.g, 2AgCl=2Ag+Cl2

e. Thermal decomposition- when a decomposition reaction is carried out by heating is called thermal decomposition reaction. E.g, CaCO3= CaO+CO2

f. Displacement reaction- a reaction in which a more reactive element displaces a less reactive element from its compound is called a displacement reaction. E.g,   Fe+CuSO4= FeSO4+Cu

g. Double displacement reaction- reactions in which there is an exchange of ions between the reactants are called double displacement reaction. E.g,  BaCl2+H2SO4=BaSO4+HCl.

h. Precipitation reaction- any reaction that produces a precipitate can be called a precipitation reaction. E.g,  Na2SO4+BaCl2= BaSO4+2NaCl.

i. Redox reactions- the reaction in which one reactant gets oxidized while the other gets reduced during a reaction is called a redox reaction. E.g, CuO+H2 = Cu+H2O
