Question

define various types of chemical reactions . write one chemical equation for each type​

Answer 1

Answer:-

Chemical reaction is a chemical change that occurs in the reactants to form the products.

The types of chemical reactions are:-

• Combination Reaction
• Decomposition Reaction
• Displacement Reaction
• Double Displacement Reaction
• Oxidation and Reduction Reaction

-------------

Combination:-

When two reactants react to form a single product is known as a combination reaction.

CaO + H2O ---> Ca(OH)2 + Heat

Decomposition:-

When one reactant break down into simpler products is known as decomposition reaction.

CaCO3 ---(Heat)--> CaO + CO2

Displacement:-

When one element and compound reacts where the element displaces the element in the compound, is known as a displacement reaction.

Fe + CuSO4 ---> FeSO4 + Cu

Double Displacement:-

When two compounds react and there is a displacement of the elements in the compounds, then this reaction is called as double displacement reaction.

Na2SO4 + BaCl2 ---> BaSO4 + 2NaCl

Oxidation and Reduction Reaction:-

When in a reaction something is oxidized and something is reduced,it can be called as oxidation and reduction reaction or redox reaction.

Oxidation happens when oxygen is added to something or hydrogen is reduced from something. And reduction happens when oxygen is reduced from something or hydrogen is added to something.

CuO + H2 ---(Heat)---> Cu + H2O
