Question

Define the following: a) Displacement reaction b) Neutralization reaction c) Photochemical reaction d) direct combination reaction

Answer 1

➜ Displacement reaction:- is a chemical reaction in which one element is replaced by another in a compound.

➜Neutralization reaction:- is a chemical reaction in which acid and a base react quantitatively with each other. In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present in the solution.

➜Photochemical reaction:- A photochemical reaction is a chemical reaction triggered when light energy is absorbed by a substance's molecules.

➜direct combination reaction:-direct combination reaction is a type of chemical reaction in which two or more simple substances combine to form a more complex product.
