Plastics and Polymers

Yes, nucleotides form polymers called nucleic acids. Nucleic acids are long chains of nucleotides that are essential in storing and transmitting genetic information. DNA and RNA are examples of nucleic acids formed by nucleotide polymers.

Plastic bags are bad for the environment because they take a long time to decompose, contributing to landfill waste and releasing harmful toxins as they break down. Additionally, the production and disposal of plastic bags contribute to air and water pollution, disrupting ecosystems and harming plant and marine life.

Thermosoftening polymers are used in a wide range of applications such as packaging materials, textiles, toys, and medical devices. They can be easily molded into different shapes when heated and can be recycled by melting and reshaping, making them versatile materials for various industries.

The smallest unit of a polymer is called a monomer. Monomers are the repeating units that link together to form a polymer chain through chemical bonds.

Even though there are some variants among biochemists, we can consider this: a chain or polymer consisted of 2 to 10 or 12 amino acids is called a peptide. A polymer formed by 12 to 20 or 25 amino acid chain is called a polypeptide. And a polymer of more than 20 or 25 amino acids is called a protein.

Initiator efficiency in free radical polymerization is typically low because not all initiator molecules generate active radicals that are capable of initiating polymerization reactions. This is due to side reactions such as termination or chain transfer processes that can reduce the number of active radicals available for polymerization. Additionally, some radicals may not efficiently propagate the polymerization due to their reactivity or stability.

Carbon is the element that forms the backbone of most polymers due to its ability to form strong covalent bonds with other carbon atoms, creating long chains or networks that make up the polymer structure.

Polymers are not made into crude oil. Crude oil is composed of a mixture of hydrocarbons that are naturally occurring in the earth's crust. However, polymers can be derived from crude oil through a process called polymerization, where small molecular units (monomers) derived from crude oil are chemically bonded together to form long chains known as polymers.

A flat round portable metal disc with a plastic coating is likely a portable hard drive. This device is used to store and transfer digital information such as documents, photos, and videos. The plastic coating serves as protection for the metal disc inside.

Acrylic plastic is actually quite strong

Acrylic many times stronger than glass, making it much more impact resistant and therefore safer. Falling against an acrylic shower door will not likely break it. Baseballs that crash through glass windows will, in most cases, bounce off acrylic windows.

A combination of various polymers are used such as Hydroxypropyl cellulose, carboxymethyl cellulose and many others. These sustained release (XR, ER, SR) tablets may or may not be film coated as well.

Yes, plastic is a type of matter. Matter is anything that has mass and takes up space, and plastic fits these criteria as it has mass and occupies volume.

it is a synthetic polymer. depends on how you made it

Polymers can be both depending upon which ones you are asking about. Polymer simply means "a chain of identical molecules linked together". Nonrenewable polymers would be plastics made from crude oil; renewable polymers would be cellulose and lignin in tree trunks.

This is a valid statement, however it requires a little mind bending. Large organic molecules essentially are linked polymers to create a monomer. However, traditionally monomers are considered to be molecules that link easily in a chain and polymers are the chain, so in that way, this statement could be considered incorrect.

polythene is a kind of polymer. It cant be decomposed. If u opt for recycle process for the polythene it will emit only poisoneous gases and resultant product will be only polythene.

Now, u can use this polythene for making roads. The use of polythene in roads strenghtens the quality of road. though it cant be recycled but now u can use it in roads coaltar.

some plastics are and some aren't :)

As a general rule, the thicker, denser, and harder the plastic, the more likely it is to be nonporous

Plastics that are elastic, moldable, easily broken, think and lack density and toughness will be porous, for example, saran wrap or grocery bags

PVC or polyvinyl chloride is a polymer created from the alkene monomer vinyl chloride (CH2=CHCl)

in polymers you have covalent bonding between the atoms of C & H as both are not metals.

I think so but I'm not very sure my freinds at school eat some and they came to school perfectly heathy I think

They are wrapped to increase shelf life of the cucumber as respiration of the fruit through its' thin skin will cause it to deteriorate and go soft. The wrap also protects the fruit from damage but that is a secondary benefit.

Well that is a vague question that really depends on what kind of cloth you are referring to, what kind of plastic bag and what you define as a bunch.

Carbon fiber reinforced plastic and carbon fiber reinforced polymer refer to the same material, which is a composite made of carbon fiber and a polymer matrix. The terms are often used interchangeably, with the most common polymer matrix being epoxy resin. Both materials offer high strength-to-weight ratios and are used in a variety of applications such as aerospace, automotive, and sports equipment.

Menu dispensers are commonly made out of materials such as acrylic, wood, metal, or plastic. The choice of material depends on factors like durability, aesthetic appeal, and budget.

The concave plastic discs on the sidelines of football games are called pylons. They are used to mark the corners of the end zone to assist referees and players in determining the boundaries of the field. Players must cross the goal line inside these pylons to score a touchdown.
