Yes it id .
When borax is mixed with polyvinyl alcohol, a chemical reaction occurs that creates a polymer known as polyvinyl alcohol-borate complex. This polymer forms a network structure that gives the mixture a slimy and viscous texture, commonly known as "slime".
no, phosphorus is an element.

One example of a polymer with a complex structure is a dendrimer. Dendrimers are highly branched macromolecules with a symmetrical and well-defined architecture. They have unique properties due to their multivalent nature and can be tailored for various applications such as drug delivery and nanotechnology.
Which of the following is not a polymer? A) cellulose B) glucose C) starch D) DNA E) chitin
No, melanin is not classified as a polymer. It is a complex biopolymer derived from the oxidation of the amino acid tyrosine, forming a heterogeneous group of pigments. While it has polymer-like characteristics due to its large, complex structure, it does not fit the traditional definition of a polymer, which is typically a long chain of repeating units. Melanin's unique structure contributes to its diverse functions in biological systems, such as photoprotection and coloration.
Yes, bread contains polysaccharides such as starch, which is a type of polymer made up of glucose molecules. Therefore, bread can be considered a polymer due to its complex structure of macromolecules.
Milk is not a polymer or a monomer. It is a complex mixture of components such as water, proteins, fats, carbohydrates, and minerals. Each component in milk has its own chemical structure and properties.
PolyVinyl Alcohol is a synthetic polymer and it is Halal.
Cross-linking a polymer like polyvinyl alcohol or rubber creates covalent bonds between individual polymer chains, which enhances the material's mechanical strength, elasticity, and thermal stability. This process restricts the movement of polymer chains, resulting in a more rigid and durable structure compared to the unlinked form. To illustrate these relationships in a diagram, you could depict a monomer as a single unit, show it joining to form a polymer (a long chain of repeating units), and then represent cross-linking by drawing connections between different polymer chains to highlight the network structure of the cross-linked polymer.
Ethyl alcohol, also known as ethanol, is a simple alcohol with the chemical formula C2H5OH, primarily used as a recreational beverage, solvent, and in various industrial applications. Polyvinyl alcohol (PVA), on the other hand, is a synthetic polymer made from the polymerization of vinyl acetate, with a structure that contains repeating units of vinyl alcohol; it is used in applications such as adhesives, films, and coatings. While ethyl alcohol is a small molecule that is volatile and water-soluble, polyvinyl alcohol is a larger, solid polymer that forms films and is not volatile.
