Question

explain the deffrent type of camical reaction with example​

Answer 1

Answer:

Combination reaction

1. Two or more reactants combine together to form single product.
2. They are exothermic.
3. Eg- Ca+ H2O ---> Ca(OH)2+ heat

Decomposition reaction

1. Single reactant decomposes into two or more simpler products
2. They are endothermic.
3. Eg- 2FeSO4(in presence of heat)--> Fe2O3 + SO2+ SO3

Displacement reaction

• More reactive metal displaces less reactive metal.
• Eg- Fe + CuSO4 ----> FeSO4 + Cu

Double Displacement reaction

• Ions are exchanged and new substance are formed.
• Eg- BaCl2 + Na2SO4 ---> 2NaCl + BaSO4

Reduction

• Loss of oxygen or gain of hydrogen take place
• Eg-2 H2O --->2H2+ O2 , water is reduced.

Oxidation

• Gain of oxygen or loss of hydrogen
• Eg- 2H2+ O2---> 2H2O, hydrogen is Oxidised.
