Question

C2H4 > -[CH2-CH2]-n

Answer 1

это реакция полимеризации

из этена (этилена) образуется полиэтилен

C₂H₄ + C₂H₄ + C₂H₄ + .n... ---> (-CH₂-CH₂-CH₂-CH₂-CH₂-CH₂-)n

Answer 2

The chemical equation you provided, C2H4 -> -[CH2-CH2]-n, represents the polymerization of ethylene (C2H4) to form a polyethylene chain (-[CH2-CH2]-n).

Polyethylene is a common plastic that is produced on a large scale worldwide. It is created through a process called polymerization, where small molecules called monomers are chemically linked together to form long chains known as polymers. In the case of polyethylene, the monomer is ethylene (C2H4).

When ethylene molecules undergo polymerization, the double bond between the carbon atoms in each ethylene unit is broken, and the carbon atoms join together to form a chain. The repeating unit in the resulting polyethylene chain is [-CH2-CH2-]. The "n" in the chemical equation represents the number of repeating units or monomers in the polyethylene chain, indicating that the chain can be of varying lengths.

Overall, the equation C2H4 -> -[CH2-CH2]-n illustrates the conversion of ethylene monomers into a polyethylene polymer chain through polymerization.
