Question

differentiate between displacement and double displacement reaction (2 points)​

Answer 1

answer:-

A chemical reaction in Which a more reactive element displaces a less reactive element from its compound is called a displacement reaction.

A chemical reaction in which two substance exchange their atoms or ions to form products is a called a double displacement reaction

Answer 2

single displacement

A single-replacement reaction is a chemical reaction in which one element is substituted for another element in a compound, generating a new element and a new compound as products.

For example,

2HCl(aq)+Zn(s)→ZnCl2 (aq)+H 2(g)

is an example of a single-replacement reaction.

The hydrogen atoms in HCl are replaced by Zn atoms, and in the process a new element hydrogen is formed.

The double displacement.

A double-displacement reaction occurs when parts of two ionic compounds are exchanged, making two new compounds. A characteristic of a double-replacement equation is that there are two compounds as reactants and two different compounds as products.

An example is

CuCl2(aq)+2AgNO3 (aq)→Cu(NO3)2 (aq)+2AgCl(s)

There are two equivalent ways of considering a double-replacement equation,either the cations are swapped, or the anions are swapped.
