Which makes better packing material: a high density or low density material? why?

Explanation:

Density is defined as mass of a substance divided by volume of the substance.

Mathematically,        Density =

As density is directly proportional to mass. So, more is the mass of a substance more will be its density.

And, more is the density of a substance more strength it will hold. And, when it will be used as a packaging material then it will not easily rip or tear apart.

As a result, it will keep the item or object safer.

On the other hand, a packaging material with low density can easily rip or can be crushed. So, it will not keep the item inside it safer.

Thus, we can conclude that a high density material makes better packing material.

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.
