Answer 1

Answer:

When copper wire is submerged in an aqueous solution of FeCl₃, no reaction takes place.

Explanation:

To answer this question, we will use the reactivity series of metals to predict the result of this reaction.

Here is the reactivity series of metals in decreasing reactivity:

Potassium

Sodium

Calcium

Magnesium

Aluminium

Zinc

Iron

Tin

Lead

Copper

Silver

Gold

Note:

i) The reactivity series can be used to predict the result  of a reaction

ii) A more reactive metal displaces a less reactive metal in a reaction.

III) A less reactive metal cannot displace a more reactive metal in a reaction.

Copper (Cu) is a less reactive metal than iron (Fe) according to the reactivity series, therefore copper cannot displace iron in the reaction.

When the copper wire is placed in the Iron(III)chloride solution (FeCl₃), no reaction takes place as copper is less reactive than iron and cannot displace it in a reaction.
