Polyethylene is synthesized from ethylene which is a compound derived from natural gas or petroleum. It’s essentially a thermoplastic, implying that it can be molten and remolded into the desired shape making it reusable and cost-effective. Of all the different kinds of plastics produced around the world, polyethylene is the most common and significant.
Polyethylene is manufactured in three different forms namely:
Low Density Polyethylene (LDPE),High Density Polyethylene (HDPE) andLinear Low Density Polyethylene (LLDPE),
Each of these three plastics has different applications ranging from containers, packaging and films to buckets and bottles.

There are 3 major types of radiation. The Alpha, Beta and Gamma radiation. It is the Alpha radiation that can be stopped by a piece of paper or fabric. Beta on the other hand can be stopped by plastic or a thin sheet of metal and Gamma by a piece of aluminum foil or lead.

Answer:
moles of water in
of water.
Explanation:
Mass of water = ![m = 2.5\times 10^{18} g](https://tex.z-dn.net/?f=m%20%3D%202.5%5Ctimes%2010%5E%7B18%7D%20g)
Molar mass of water = M = 18 g/mol
Moles = n = ![\frac{m}{M}](https://tex.z-dn.net/?f=%5Cfrac%7Bm%7D%7BM%7D)
![n=\frac{2.5\times 10^{18} g}{18 g/mol}=1.39\times 10^{17} moles](https://tex.z-dn.net/?f=n%3D%5Cfrac%7B2.5%5Ctimes%2010%5E%7B18%7D%20g%7D%7B18%20g%2Fmol%7D%3D1.39%5Ctimes%2010%5E%7B17%7D%20moles)
So, there are
moles of water in
of water.
Answer:
1) Oil is less dense than water so when oil spills, it spreads across the entire water surface.
2) The oil spreads very quickly with lighter oils such as gasoline.
3) Wind, Currents, and Warm Temperatures will cause Oil to spread quicker.
