What is the process when alkenes are used to make polymers?
When alkenes are used to make polymers, a process called polymerization occurs where the alkene monomers (such as ethylene or propylene) undergo a chemical reaction to form long chains of repeating units. This reaction can be initiated by heat, light, or a catalyst, resulting in the formation of a polymeric material with desirable properties for various applications.
Are monomers made up of many polymer units?
No. Amino acid monomers are used to make protein polymers. Nucleotide monomers are used to make DNA polymers.
Identify the metal used as the catalyst in the Haber process?
its Fe- iron. It is used as a catalyst to speed up the exothermic reaction between N2 and H2 to make NH3.
What is ferrocene used for?
Ferrocene is used as a catalyst in organic synthesis, particularly in the production of pharmaceuticals, polymers, and fine chemicals. It is also used as an anti-knock additive in gasoline to improve fuel efficiency. Additionally, ferrocene has applications in materials science, such as in the development of magnetic materials and batteries.
Is a catalyst used up in a reaction?
Yes, a catalyst can be re-used, because It is NOT actually used in a chemical reaction. A catalyst will increase the rate of reaction by attracting reactants, but the catalyst is not a reactant. However, the reuse cannot be done indefinitely then, depending on the severity of the reaction conditions, it can be occur a small, but accumulative deactivation of the catalys.
How PCV is done?
PVC or polyvinylchloride is a material used to make raincoats, according to my science teacher. i was learning it today and she said something to do with polymers n bonding you do polymerisation and it requires a high pressure and a catalyst - i used broken pottery.
What are short molecules used to make polymers?
monomers
How are alkenes used to make polymers?
Alkenes are used to make polymers through a process called polymerization, where the double bond in the alkene is used to form the backbone of the polymer chain. By initiating polymerization reactions with catalysts, heat, or light, alkenes can be linked together to form long chains of repeating units, creating various types of synthetic polymers. Examples include polyethylene, polypropylene, and polystyrene.
Why are polymers used in health care?
They are used to make containers for medicines and also equipment.
What is the catalyst used to make sulfuric acid nitric acid ammonia ethene and magarine?
Ammonia = iron catalyst
When did polymers become big business?
The second world war was the catalyst for huge change. The Allies had no access to Malaysian rubber plantations so synthetic polymers were developed in a large way.

Scope of polymer technology?
There is huge scope for polymers because of thir application in various fields. eg. biopolymers, manf of appliances, catalyst supports, hydrophilic polymers, in medicines, in surfactants etc.
What is an acetamidoacrylate?
An acetamidoacrylate is the acetamido derivative of an acrylate, used to make specialist polymers.
Are monomers made up of many polymer units?
No. Amino acid monomers are used to make protein polymers. Nucleotide monomers are used to make DNA polymers.
What are the sources of sugar based polymers?
The ultimate source of natural sugar based polymers are plants. Plants make sugar (glucose) by photosynthesis. The glucose is then used to make polymers such as starch (amylose and amylopectin) and cellulose. See: http://en.wikipedia.org/wiki/Polysaccharide
What is a catalyst only used in photosynthesis?
Chlorophyll is the catalyst that is used in the process of photosynthesis.
