Question

Examples of chemical reactions and types of chemical reactionswith definistions class10

Answer 1

Here is your answer:-

Examples of chemical Reaction is C+O2->CO2

There are five types of chemical Reaction:-

Composition reaction:-Those reaction in which two or more substances combine to form a single substance.
ex- C+O2-> CO2.

Decomposition reaction:-Those reaction in which a compound splits up into two or more simpler substances.

Displacement reaction:- Those reaction in which one element takes place of another element in a compound.

Double displacement reaction:-THOSE reaction in which two compounds react by an exchange of ions to form two new compounds are called double displacement reaction .

Oxidation reaction:- Those reaction in which addition of oxygen to a substance or removal of hydrogen form a substance take place.

Answer 2

There are total 9 types of the chemical reactions.
They are named as follows :-

1. Combination reaction

When 2 or more reactants combine in a reaction to form a single product, it is called as Combination reaction.

Example
2Mg + O2 ==> 2MgO

2. Decomposition reaction

The chemical reactions in which two or more products are formed from a single reactant is called a decomposition reaction.

Example
CaCO3 ==> CaO + CO2

3. Displacement reaction

The reaction in which the place of ion of a less reactive element in a compound is taken by another more reactive element by formation of its own Ion is called a displacement reaction.

Example
CuSO4 + Zn ==> ZnSO4 + Cu

4. Double Displacement reaction

The reactions in which the ion in the reactants are exchanged to form a precipitate are called double displacement reactions .

Example 
AgNO3 + NaCl ==> AgCl + NaNO3

5. Endothermic Reaction

The chemical reactions which are accompanied by absorption of heat are called endothermic reactions.

Example
CaCO3 + Heat ==> CaO + CO2

6. Exothermic reaction

The chemical reactions which are accompanied by evolution of heat are called Exothermic reaction.

Example
CaO + H2O ==> Ca(OH)2 + Heat

7. Reduction Reaction

The chemical reaction in which hydrogen is gained and oxygen is losed is called as Reduction Reaction.

Example
C + 2H2 ==> CH4

8. Oxidation Reaction

The chemical reaction in which a reactant combines with oxygen or loses hydrogen is called as Oxidation Reaction.

Example
MgH2 ==> Mg + H2

9. Redox Reaction

The chemical reaction in which both reduction and oxidation reaction takes place simultaneously is called Redox Reaction.

Example
CuO + H2 ==> Cu + H2O

These are the types of reaction.
