Question

write two differences between displacement and double displacement reaction. Write one equation of each of these two types of reaction​

Answer 1

Answer:

ANSWER

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)→ZnCl

2

(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.

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 CuCl

2

(aq)+2AgNO

3

(aq)→Cu(NO

3

)

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.
