Silver chloride (or silver bromide) and copper(II) chloride

Polyester resin and glass fibers

None

Styrene-butadiene rubber is used to make vehicle tires. Based on its name and the provided text, what type of material is it?

A copolymer

A ceramic composite

A superconductor

A natural polymer

None

Which of the following pairs correctly matches a natural polymer with its corresponding monomer?

Carbohydrate (Starch) and Isoprene

Protein and Glucose

Protein and Amino acid

Natural rubber and Amino acid

None

The development of nanoscience and nanotechnology, which produced materials like carbon nanotubes, involves working at what scale?

The atomic scale (less than 1 nanometer)

The macroscopic scale (greater than 1 millimeter)

The nanoscale (1-100 nanometers)

The microscopic scale (1-100 micrometers)

None

The text identifies a major environmental issue with the disposal of advanced materials in electronic products. What is a primary reason that electronic waste (e-waste) is so harmful?

It is highly radioactive and requires specialized containment.

It biodegrades too quickly, releasing nutrients that upset ecosystems.

It is often disposed of through open burning, which releases toxic gases.

It absorbs a large amount of water, leading to soil dehydration.

None

How do fiber optic cables transmit information, making them advantageous over traditional copper wires?

They transmit data as signals of light, allowing for higher speed and capacity

They use superconductive materials to send electrical signals with zero loss.

They vibrate at high frequencies to transmit data acoustically.

They use magnetic pulses, which are not affected by electrical interference.

None

Nylon, commonly used for ropes, carpets, and clothing, is a synthetic copolymer. What does this imply about its monomer composition?

It is a modified version of the natural polymer, protein.

It is formed from two different types of monomers, hexanedioic acid and hexamethylene diamine.

It is made from repeating units of the natural monomer isoprene.

It is made from a single, complex monomer called ‘nylonene’

None

Fiberglass is a composite material valued for being strong, lightweight, and corrosion-resistant. What are its two primary components?

Steel rods and concrete

Glass fibers and polyester resin (a type of plastic)

Silver chloride and regular glass

Carbon atoms and polymer chains

None

What property of the synthetic polymer Perspex (Polymethyl methacrylate) makes it suitable for use in aircraft windows and car lights?

It is lightweight, strong, and transparent.

It is opaque and absorbs all light.

It is a good electrical conductor.

It is soft and highly elastic

None

10.

What is the defining characteristic of a superconductor when it is cooled below its critical temperature?

It converts electrical energy into heat energy with 100% efficiency.

It exhibits zero electrical resistance

It develops extremely high electrical resistance.

It becomes a perfect insulator.

None
