The question above wants to assess your ability to create a model to represent a scientific concept. In that case, I can't create the model for you, but I'll show you how to create that template.
First, you must choose one of the topics presented in the question. I suggest that you choose the topic "Conservation of Masses," because of its simplicity, however you should choose the one you are most familiar with.
Next, you should research this topic and look at the factors that make it up.
After that, you can create your template as follows:
- Use a software that has ready-made drawings, mainly geometric figures, for you to represent the elements that make up this topic.
- Use these drawings to represent these elements, place titles that identify them, and add arrows, which direct the viewer's attention to understand the model.
You can see examples of "Conservation of Masses," models in the attached figure.

Answer:
There are 12 lone pairs of electrons on the molecule.
The formal charge on carbon is zero.
There are 4 covalent bonds within the molecule.
Explanation:
The formal charge(FC) can be calculated by the equation:
FC = V - N - B/2, where V is the number of the valence electrons of the neutral element, N is the number of non-bonding valence electrons, and B is the total of electrons shared in bond.
The Lewis structure is represented in the image below. F and Br have 7 valence electrons and C 4 valence electrons.
So, for C, FC = 4 - 0 - 8/2 = 0
For the both Br, FC = 7 - 6 - 2/1 = 0
For the both F, FC = 7 - 6 - 2/1 = 0
For the structure, we can see that there are 12 lone pairs of electrons on the molecule (3 in each Br and 3 in each F).
All the bonds are covalent because the atoms are sharing a pair of electrons, so there are 4 covalent bonds within the molecule.
