Is the formation of polyethylene from ethylene a chemical reaction?

Polyethene is created through the polymerization of ethene. Under the right conditions of temperature, pressure and catalysis, the double bond of the ethene monomer opens up and many monomers link up to form long chains. Polyethene manufacturing processes are usually categorized into "high pressure" and "low pressure" operations. The former is generally recognized as producing conventional low density polyethene (LDPE) while the latter makes high density (HDPE) polyethene. The difference between these polyethene processes is that LDPE is formed at 1000 - 3000 bar and 80 - 300 degrees C in the presence of minute quantities of oxygen, and HDPE is formed at 10 - 80 bar and 70 - 300 degrees C in the presence of an aluminium-based catalyst.

How many ponds of ethylene to make a pound of polyethylene?
When completely reacted, one pound of ethylene will make one pound of polyethylene, because no atoms are lost or gained in the reaction.
Is polymerize to form polyethylene a chemical or physical?
Polymerization is not a property; it is a type of chemical reaction.
How can you know this is a chemical reaction?
Evidence of a chemical reaction include the following: formation of a precipitate formation of a gas change in temperature change in color
What is the 2nd observable characteristic of a chemical reaction?
There are many observable characteristics of a chemical reaction. They are: change in temperature formation of a precipitate change in color formation of a gas formation of a new odor disappearance of a solid
What take place during a chemical reaction?
During a chemical reaction the breaking of the older bonds and formation of the new bonds take place.

What is the chemical reaction for the formation of rubber?
The type of chemical reaction that takes place through the formation of the rubber is called the mechano-chemical reaction. Through this, it gives the end product a three dimensional structure.
What is the chemical reaction of HF and water?
Not a chemical reaction, but the formation of a water solution of hydrofluoric acid.
Is polyethylene a raw material?
No Polyethylene(one of the commonly known plastics) is created through polymerization of ethene (also known as Ethylene). Ethylene is created by steam cracking. Basically mixing really hot steam around (850 C) with ethane, LPGs or light naphthas. Some of the product of the reaction is Ethylene. Naphthas comes from the refining of crude oil and Ethane comes from natural gas.
Formation reaction for C2H6O?
A chemical reaction is:C2H4 + H2O → C2H5OH
What is usually evident of a formation of a precipitate?
Formation of a precipitate is evidence of a chemical reaction.
