tatyana61 [14]

In the given question according to the information the process of polymerization is an addition polymerization.

<h3>What is polymerization?</h3>

Polymerization is a process in which addition of many small molecules takes place for the formation of a large three dimensional substance known as polymer.

In the polymerization of polyethene the small repeating molecule is ethene and in this process product formed due to the addition process to the double bond of the ethene.

  • In condensation polymerisation removal of water molecule or any other molecule takes place.
  • In dehydrogenation polymerisation removal of hydrogen molecule takes place.
  • In dehydrohalogenation polymerisation removal of hydrogen halide molecule takes place.

Hence given process is an addition polymerisation.

An important difference between fuel cells and batteries is that batteries _______. Select the correct answer below: do not requ
aliya0001 [1]

Answer: the correct option is that batteries (do NOT require a continuous source of fuel).

Explanation:

A battery can be classified as an electrochemical cell that has the ability to produce electric current. They do NOT require a continuous supply of fuel because it contains all the reactants needed to produce electricity. Below are some examples of batteries that are commonly used:

--> Primary battery: This is a single use battery because it can't be recharged. A typical example is the dry cell.

--> Secondary battery: This type of battery can be recharged. They are used as a power source for smartphones, electronic tablets, and automobiles.

A FUEL CELL is known as a device that converts chemical energy into electrical energy. Fuel cells are similar to batteries but require a continuous source of fuel, often hydrogen. They will continue to produce electricity as long as they are constantly resupplied with reactants. Hydrogen fuel cells have been used to supply power for satellites, space capsules, automobiles, boats, and submarines.
