Answer:
they are made from synthesized polymers of small molecules.
Explanation:
The compounds that are used to make these fibers come from raw materials such as petroleum based chemicals or petrochemicals. These materials are polymerized into a chemical that bonds two adjacent carbon atoms.

Answer:
a reducing agent .
Explanation:
In the extraction of iron, carbon monoxide acts as the main reducing agent.
Carbon monoxide is a neutral, colorless and odorless gas. One of the property of carbon monoxide is that it is a powerful reducing agent as it combines with oxygen readily to form CO₂ and hence its use in metallurgy.
- A reducing agent is one that undergoes oxidation in a chemical process.
- The carbon monoxide is produced in the furnace at high temperature.
- Carbon dioxide combines with carbon to produce carbon monoxide.
So, carbon monoxide acts as the main reducing agent.
