5. Based on your observations, are any of the substances shown on this form the same substance? Why or why not?

Explanation:

1. the substance is dry and and slightly clumped together yet still has some powdery parts to it.

2. the substance is dry aswell, but also seems to be more flaky than powdery. the "chunks" are big enough to the point where you could most likely easily pick the individual pieces apart.

3. this substance is very powdery, to the point where it seems like I would compact easily. in the image, there is really no "stray pieces", it is all in one neat pile.

4. this substance very powdery, which we can see because the "pieces" are so small that they easily stick and clump together.

5. no, none of the substances are the same. while they do have a lot of similar properties, it is clear to see they are still all very different.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
