Question

Define the following 1. Chemistry 2. Displacement reaction 3. Combination reaction

Answer 1

Answer:

Displacement reaction:-

A displacement reaction, is a chemical reaction in which one element replaces an/other element in a compound. It can be represented generically as: A + B-C → A-C + B This will most often occur if A is more reactive than B, thus giving a more stable product.

Combination reaction:-

A combination reaction is a reaction where two or more elements or compounds combine to form a single compound. Such reactions is represented by equation of the following form: X + Y → XY. The combination of two or more elements to form one compound is called combination reaction.

I hope that it would be helpful.

Answer 2

combination reaction when two substance reactant and combine with each other to form a new product is known as combination reaction

displacement reaction =when highly reactive substance display low active substance from its salt is known as displacement reaction

Chemistry= the scientific study of a structure of substance and what happens to them in different condition and what mixed with each other is known as a chemistry
