Compare the polymerisation reaction used to produce poly(ethene) with the
butalik [34]

Answer:

See explanation

Explanation:

Polymerization is the process whereby two or more monomers link together to form a compound of high molecular mass called a polymer.

There are two kinds of polymers;

-Addition polymers

-Condensation polymers

Addition polymers are formed by the joining of two or more monomers  to form a polymer without the elimination of a small molecule.

Condensation polymers are formed by the joining of two or more molecules  to form polymers with the elimination of a small molecule.

The main difference between polyethene and polyester is that polyethene is an addition polymer while polyester is a condensation polymer.

In polyethene, ethene molecules are joined together having the repeating unit as [-CH2-CH2-]n.

In polyester, the polymer arises from the reaction of carboxylic acid and an alcohol and loss of water molecules.

Gaseous methanol (CH4O) reacts with oxygen gas to produce carbon dioxide gas and liquid water. Balanced the equation using the l
NikAS [45]

Answer:

The sum of the coefficients in the balanced equation is 11

Explanation:

A reaction where an organic compound reacts with oxygen to produce carbon dioxide and water is called combustion.

The balance reaction of combustion for methanol is:

2CH₃OH (l) + 3O₂(g) →  2CO₂(g)  +  4H₂O (g)

Coefficients from stoichiometry are 2, 3, 2 and 4

Sum =  2 + 3 + 2 + 4 = 11
