Explanation:
Styrene is a vinyl monomer in which there is a carbon carbon double bond.
The polymerization of the styrene, which is initiated by using a free radical which reacts with the styrene and the compound thus forms react again and again to form polystyrene (PS).

Answer:
I think
electromagnets require power to operate
Answer:
If analyzed by volume capacity, more trips are needed to fill the space, thus the required trips are 288
Explanation:
a) By volume.
The shrinkage factor is:

The volume at loose is:

If the Herrywampus has a capacity of 30 cubic yard:

b) By weight
The swell factor in terms of percent swell is equal to:


The weight of backfill is:

The Herrywampus has a capacity of 40 ton:

If analyzed by volume capacity, more trips are needed to fill the space, thus the required trips are 288
D) cost
The fund available for a project is the first factor to be considered to ensure that the project comes to reality and serve it’s purpose
