HideShow resource information
what are the molecules called, they join in a link to form a polymer?
monomers or as a substitute an alkene.
1 of 6
what happens to the molecule as it joins to form a polymer compound?
the double bond is moved to form a link with other monomers.
2 of 6
what are polymers used as?
as useful plastics in materials such as waterproof coatings and shopping bags.
3 of 6
what dose it mean by bio-degradable? are most polymers bio-degradable?
the material is broken down my microbes but in most polymers it cannot broken down easily by small microbes as they find it hard to digest.
4 of 6
what should we do about this as it becomes a disposal problem?
make the materials more biodegradable by adding things like cornstarch and start recycling or reusing the material
5 of 6
state both ways of creating ethanol from an alkene!
through hydration in seam in the presence of a catalyst, or through fermentation. sugar--> carbon dioxide + ethanol
