Plastics and Polymers

The building blocks of plastics are called monomers. These are small molecules that can join together to form long chains known as polymers through a process called polymerization.

As more and more countries are demanding the reduction in plastic bag used (because of their environmental impact) then Paper based packaging is prefered and because of it recyclable capabilities they can be reused for creating more paper at a latter stage.

Hydrolysis. Polymers are broken down into monomers in a process known as hydrolysis

No, proteins are polymers of amino acids.

DNA and RNA are polymers of nucleotides.

No, substances like wood and plastic are not as good heat conductors as metals. Metals have free electrons that allow heat to transfer quickly through them, while wood and plastic are insulators with a higher resistance to heat flow.

The monomer subunit of lipids is fatty acids. Fatty acids consist of a long hydrocarbon chain with a carboxyl group at one end. Additionally, lipids can include other molecules such as glycerol and phosphate in their structure.

The smallest unit is the carbon atom, followed by the monomer, which is a single repeating unit of a polymer. The macromolecule is the largest structure, made up of multiple monomers linked together to form a polymer chain.

Glucose is a nutritional monomer that can be transported in the blood. After digestion of carbohydrates in the diet, glucose is absorbed into the bloodstream and carried to cells throughout the body to provide energy.

PVC plastics are commonly used to make pipes, window frames, credit cards, flooring, and vinyl records due to their durability and versatility.

Plastic spoons are usually lighter, smoother, and more resistant to moisture compared to wooden spoons. Wooden spoons are typically heavier, have a warmer feel, and are less likely to scratch or damage cookware.

No, polymerization is not an example of a decomposition reaction. Polymerization is a process where monomers combine to form a polymer, while decomposition reactions involve breaking down a compound into simpler substances.

Proteins are made of amino acid chains. The repitition closely resembles the repeating unit, the monomer, from polymers. Lipids are made of trigyclerides and fatty acids, much smaller molecules than the protein, which is a macromolecule.

Polymerization can be anobolic or catabolic when it is taking place in biomolecules.Anabolic if, set of metabolic pathways lead to construct molecules from smaller units which require energy and catabolic if, set of pathways break down molecules into smaller units and release energy.

Yes!

Depends which plastic and which rubber you are talking about. It really is quite alarming how people use terms like "Plastic" and "rubber" when there are HUGE numbers of massively different products falling under each category. You wouldn't say "Come round for dinner tonight, we're having 'food' followed by 'food' and then some 'food' for dessert" would you??

DNA is considered a polymer because it is made up of repeating units called nucleotides, which are linked together in a long chain. These nucleotides consist of a sugar molecule, a phosphate group, and one of four nitrogenous bases (adenine, thymine, cytosine, or guanine). The repetitive nature of these units forms a polymer structure.

One way to join plastics together for children to understand is by using a non-toxic and safe adhesive specifically designed for plastics. You can teach children how to apply a small amount of the adhesive to the surfaces they want to join together, then press them firmly until the bond sets. It's important to emphasize safety precautions and supervise children while they are working with adhesives.

Switches are typically made of plastic because plastic is a good insulator, which helps to prevent electrical shocks. Plastic is also lightweight, durable, and cost-effective compared to metal. Additionally, plastic can be molded into various shapes and colors easily to suit different design preferences.

Yes, the asthenosphere is a layer of the Earth's mantle that exhibits plastic behavior, meaning it can flow and deform slowly under high temperatures and pressures. This plasticity allows the lithospheric plates to move and interact with each other, leading to processes like plate tectonics.

ionic bonds :)

The monomer for water is a single water molecule, which consists of two hydrogen atoms bound to one oxygen atom. This is the smallest repeating unit that makes up water.

Amphiphilic polymers are molecules that have both hydrophilic (water-loving) and hydrophobic (water-repelling) parts. These polymers can self-assemble into structures like micelles or vesicles in aqueous solutions, where the hydrophobic parts group together to avoid water while the hydrophilic parts face outward towards the water. This property makes amphiphilic polymers useful for drug delivery, emulsification, and other applications.

The monomer or subunit of carbohydrate structure is a monosaccharide, which is a simple sugar molecule such as glucose, fructose, or galactose. These monosaccharides can combine to form larger carbohydrates like disaccharides (e.g., sucrose) and polysaccharides (e.g., starch).

Lipid polymers are molecules that combine lipid and polymer properties. They are often used in drug delivery systems and biomedical applications due to their biodegradability and ability to encapsulate drugs for targeted delivery. Lipid polymers can be tailored to have specific properties such as controlled release of drugs or improved stability in biological environments.

Polysaccharides are formed by the condensation of individual monosaccharides - in the process glycosidic bonds are formed and one molecule of water is released per bond. This is a dehydration synthesis.

Formation of proteins by the joining of individual amino acids via peptide bonds is also a dehydration synthesis with one molecule of water being produced per peptide bond.
