Draw the structures of the following covalent molecules. Label the atoms clearly.
Show the electronic configurations of the outermost shells only.

1.NHCl2

2.SiO2

3.SO2

4. BF3

5. CF2H2

NHCl_2=Attachment 1

SiO_2=Attachment 2

SO_2=Attachment 3

BF_3=Attachment 4

CF_2H_2=Attachment 5

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
