Answer : The balanced molecular equation will be:

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:

Each fee would be 2,875 pesos
The total amount of the TV would be 34,500 pesos
Cada tarifa sería de 2.875 pesos
El importe total de la televisión sería de 34.500 pesos
The F atom . Oxygen has a -2 charge and fluorine has a +1 charge
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.
