∙ 10y agoUsually, pressure and a catalyst (initiator) are applied and the result is a polyalkene or polyolefin. Examples include polyethylene and polypropylene etc.
No. The lower alkenes are gases. As the number of carbon atom increases, liquid and solid alkenes are known.
they contain unreactive atoms
Alkanes have a single bond, and Alkenes have a double bond. The general form for Alkenes is CnH(2n)
They are formed from the products (i.e alkenes and alkanes) of the fractional distillation of crude oil. Alkenes and alkanes are hydrocarbons - their molecules consist of hydrogen and carbon only. Monomers of these substances bond to form long chains called polymers. Polymers are what make up plastics.
ethene ,propene,butene
examples of alkenes are ethene, butene and pentene.
Alkenes are hydrocarbons containing carbon-carbon double bonds. There are several different names for alkenes. Some examples are butane, pentene and octadiene.
Saturated oils and waxes are all types of alkanes and alkenes The Ice man ;) Call me ladies... ;')

Examples: polyethylene terephtalate (PET), polyethylene, polypropylene.
cracking maybe?
Zoe alkenes found alkenes
Cornstarch polymers are polymers made from alkenes that are mixed with cornstarch so that they are easily biodegradeable. They are used for plastic bags so that they when they are sent to a landfill site, they biodegrade quickly and easily.
Examples: alkanes, alkenes, cycloalkanes, aromatric hydrocarbons, etc.
Not all rulers are made of plastic, you can get examples that are made of wood or even metal. However, plastic is a material that is easy to mould and this makes plastic rulers cheep to purchase. You can also see through some of them which makes them easier to use.
