I think you forgot to include the picture so that we could easily identify the bond. No matter, I can introduce the types of bonds involved in chemistry. There are only two: the sigma bond (first picture) and the pi bond (second picture).
The sigma bond is formed when the two electrons sharing an orbital are overlapped head-on. In other words, they overlap each other entirely. While a pi bond is a side-to-side overlapping kind of sharing. That is why sigma bonds are much stronger than pi bonds.
In this case, just please refer to the picture for you to identify which type of bond is it indicated in your homework.
I would say that the density increases because the distance between the molecules decreases, and therefore becomes smaller, and vice versa the density increases, and that is a physical change not a chemical change.
Answer: So you could for example say, “IF I through my clothes into the closet. THEN the floor will be visible” I capatlized if and then because you need them in a hypothesis.
