Question

What type of reaction is shown below?

Fe (s) + Cu(NO3)2 (aq) → Fe(NO3)2 (aq) + Cu (s)

Select one:
a. synthesis
b. single displacement
c. double displacement
d. decomposition

Answer 1

The reaction Fe (s) + Cu(NO3)2 (aq) → Fe(NO3)2 (aq) + Cu (s) is a single displacement reaction, where Fe displaces Cu to form Fe(NO3)2 and release Cu as a solid.

Step-by-step explanation:

The reaction shown, Fe (s) + Cu(NO3)2 (aq) → Fe(NO3)2 (aq) + Cu (s), is a type of chemical reaction where iron (Fe) displaces copper (Cu) from its compound to form a new compound, iron nitrate, while copper is released as a solid. This is an example of a single displacement reaction, specifically a metal replacement reaction, because a metal, in this case iron, is replacing another metal, which is copper. The correct answer to the type of reaction shown is single displacement (option b).

Answer 2

The correct answer is :

b. Single displacement reaction

Step-by-step explanation:

The single displacement reaction is the one in which the more reactive element substitute other element in a compound generating a new chemical compound.

It follows this kind of reactions :

`A+BC\rightleftharpoons AC+B`

Now look at the reaction given;

`Fe+Cu(NO_(3))_(2)\rightleftharpoons Fe(NO_(3))_(2)+Cu(s)`

Here the more reactive element (Fe) displaces the less reactive element [Cu]from the compound[Cu(NO3)2].

Hence Fe substitute Cu from Cu(NO3)2 and form Fe(NO3)2

It is not a double - displacement reaction . Where the elements interchange themselves to form the compound.

`AB+CD\rightleftharpoons AC+BD`
