Question

what are the displacement ,double displacement and oxidation -reduction reactions?Give one example of each reaction​

Answer 1

Answer:

Displacement reaction is a chemical reaction in which a more reactive element displaces a less reactive element from its compound. Both metals and non-metals take part in displacement reactions. For eg - Fe+CuSO4=FeSO4+Cu

Double displacement:- Those reactions in which two compounds react by an exchange of ions to form two new compounds are called double displacement reactions. For rg - 2NaCl+CaSO4​→Na2​SO4​+CaCl2​

Oxidation reaction is a reaction in which oxygen atom is added or hydrogen atom is lost. However, not all the oxidation reactions involve addition of oxygen or removal of hydrogen atoms. - The reaction in which electrons are released is called oxidation reaction. For eg - Examples: Addition of Oxygen:

(a). CuO(s) + H₂(g) → Cu(s) + H2O(l)

Hello:)

• A displacement reaction is the one wherein the atom or a set of atoms is displaced by another atom in a molecule.For Eg-when iron is added to a copper sulphate solution, it displaces the copper metal. A + B-C → A-C + B. The above equation exists when A is more reactive than B.
• Double displacement reactions may be defined as the chemical reactions in which one component each of both the reacting molecules is exchanged to form the products.For example:
• Fe2O3 + 6HCl → 2FeCl3 + 3H2O
• Double displacement reactions can be further classified as neutralization and precipitation reactions
• Oxidation reactions all reactions of organic compounds that involve oxygen as a reactant and/or lead to the formation of an oxidized form of the organic reactant. Thus oxidative dehydrogenation and ammoxidation will belong to oxidation reactions.
