ERASER: -Provide chemical formula(s), elements, physical properties and/or chemical properties. -Explain the composition (percent of each element). -Show molecules and/or structural formulas. -Show chemical reactions (if you can find them). -Does it contain ionic or covalent compound(s) or both? I have bo clue..HELP (There are natural and synthetic erasers too)

    Natural rubber is a mixture of organic compound polyisoprene and small amounts of other organic compounds as well as water. This polymer is the main component. This material is classified as an elastomer (an elastic polymer). It is derived from latex, a milky colloid produced by some plants. The plants are ‘tapped’, that is, an incision made into the bark of the tree and the sticky, milk colored latex sap collected and refined into a usable rubber. Polyisoprene can also be produced synthetically. Natural rubber is used extensively in many applications and products, as is synthetic rubber. It is normally very stretchy and flexible and extremely waterproof. Synthetic rubber is any type of artificial elastomer, invariably a polymer. An elastomer is a material with the mechanical (or material) property that it can undergo much more elastic deformation under stress than most materials and still return to its previous size without permanent deformation.
