Write the MOLECULAR EQUATION between iron and copper (II) sulfate.

Aleksandr-060686 [28]

Answer : The balanced molecular equation will be:

$Fe(s)+CuSO_4(aq)\rightarrow FeSO_4(aq)+Cu(s)$

Explanation :

Molecular equation : It is a balanced chemical reaction in which the ionic compounds are expressed as the molecules instead of component ions.

According to the question, when iron react with copper (II) sulfate then it react to give iron (II) sulfate and copper as a product. In this reaction, iron is more reactive metal than the copper metal. So, it can easily displace copper metal form the solution.

The balanced molecular equation will be:

$Fe(s)+CuSO_4(aq)\rightarrow FeSO_4(aq)+Cu(s)$

Which statement is true about BF3, a nonpolar molecule? It has nonpolar bonds and a symmetrical structure. It has nonpolar bonds

konstantin123 [22]

I think the correct answer is the first option. It has nonpolar bonds and a symmetrical structure. The structure of a BF3 molecule shows a symmetrical trigonal geometry. The net dipole moment of the molecule is zero therefore it is polar.
