Question

What is oxidation reaction, reduction reaction , combination reaction,displacement reaction ,double displacement reaction ,displacement reaction

Answer 1

Oxidation Reaction is a reaction where Oxygen is added or hydrogen is removed.

Reduction Rection is a reaction where Hydrogen is added or oxygen is removed.

Combination Reaction is a reaction in which two reactants combine to give a product.

Displacement Reaction is a reaction in which a high reactive element displaces a low reactive element to form a new compound.

Double Displacement Reaction is a type of chemical reaction where two compounds react and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products.




Hope you understood the answer.
If you like it mark it as brainly

Answer 2

Displacement reaction- In a aqueous solution when a highly reactive element displaces the lesser reactive element it is called dispalcement reaction.

Sorry not able to answer the other definitions as I have not studied the other key words yet
