Question

write any three types of chemical reactions with examples​

Answer 1

Explanation:

These all are chemical equation.

List some Examples of Chemical Equations.

PCl5 + 4H2O → H3PO4 + 5HCl.

SnO2 + 2H2 → 2H2O + Sn.

TiCl4 + 2H2O → TiO2 + 4HCl.

H3PO4 + 3KOH → K3PO4 + 3H2O.

Na2S + 2AgI → 2NaI + Ag2S.

The upper one is wrong.this was right

Combination Reaction - It is a type of reaction in which two substances chemically reacts and combines in order to give a single substance as a product. The substance could either be element or a compound, depending upon the nature of reaction.

Decomposition Reaction - It is a type of reaction in which a single substance ( also called reactant ) breaks down because of affect of light, heat or electricity in order to give one or more substances as products.

Displacement Reaction - It is a type of reaction in which a element having less chemical reactivity gets displaced by the other elements of comparitively higher chemical reactivity.

☆ Combination Reaction :-

• $2H_2(g) + O_2(g)$$\longrightarrow$ $2H_2O(l)$

• $CaO(s) + H_2O(l)$$\longrightarrow$ $Ca(OH)_2(aq) + Heat$

☆ Decomposition Reaction :-

• $2FeSO_4(s)\overset{\Delta}\longrightarrow$ $Fe_2O_3(s) + SO_2(g) + SO_3(g)$

• $2AgCl(s)\overset{\sf Sunlight}\longrightarrow$ $2AgS(s) + Cl_2(g)$

☆ Displacement Reaction :-

• $Fe(s) + CuSO_4(aq)\longrightarrow$ $FeSO_4(aq) + Cu(s)$]

• $Zn(s) + CuSO_4(aq)\longrightarrow$ $ZnSO_4(aq) + Cu(s)$]

• The Decomposition reaction can be categorised into three types :-

1. Thermolytic Decomposition - The reaction in which heat is applied in order to break a single substance ( reactant ) to give two or more substances as a product.
2. Photolytic Decomposition - Here, light is being used for the breakdown of a single substance ( reactant ) for getting two or more products.
3. Electrolytic Decomposition - The usage of electricity is done in order to break the single substance to get further two or more products.
