Answer:
The amount of matter will be the same - matter cannot be destroyed or created.
Explanation:
The state of matter could change, however, e.g. solid to liquid.
To create the Lewis structure we need to take into account the octet rule: atoms tend to gain, lose or share electrons to complete their valence shell with 8 electrons.
C belongs to Group 4A in the periodic table so it has 4 valence electrons. It needs to share 4 pairs of electrons to complete the octet.
F belongs to Group 7A in the periodic table so it has 7 valence electrons. Each F needs to share 1 pair of electrons to complete the octet.
As a consequence, in CF₄, C will form a single bond with each F and all the octets will be complete.
Examples of good electrical conductors are copper, silver, gold and aluminum

Explanation:
The question is incomplete, however, I found an example of this question on another site, so, I'm going to explain to you how to do it basing on this example, and then, apply it in your case. In the picture 1, is the example, and picture 2 is the solution.
Now, this type of reaction is known as the "<em>Williamson Ether synthesis"</em><em> </em>and the overall of this, is a reaction that involves an alkoxyde ion with an primary alkyl halide like this:
RO- + R'X ------> ROR' + X-
This is a Sn2 reaction, and it's really fast.
Following the example in picture 1, the result is in picture 2. Hope this can help you.
