Acetate fibers loose strength when wet, and acetate clothing must be dry cleaned. 60º C), and brittle when cooled below -50º C. It swells to more than double its size in nonpolar organic solvents like toluene, eventually dissolving, but is impermeable to water. If the water molecules move faster at one temperature than another, the food coloring should move faster too and make the movement easy to see.

Q: Write the name of each of the hydrocarbon. Polyesters, polyamides and polyolefins are usually spun from melts, provided the Tm is not too high. Recycling of such mixtures is a challenging problem. These are normally initiated at low temperature in methylene chloride solution.

Answer The Questions In The Table Below About This Molecule Found

PLA is actually a polymer of lactic acid, but the dimeric lactide is used as the precursor to avoid the water that would be formed in a direct poly-esterification. Nurdles, lentil-size pellets of plastic, found in abundance where plastics are manufactured and distributed, are dispersed by wind throughout the biosphere. Natural (latex) rubber is an opaque, soft, easily deformable solid that becomes sticky when heated (above. The following diagram presents one mechanism for this useful reaction. Give a short explanation why you assigned a particular molecule to this spectrum and not another. CH3 Br CO, H. A: Organic reaction mechanisms: Q: What molecule is this? Q: The difference between organic and inorganic in chemistry? This code, shown on the right, is a set of symbols placed on plastics to identify the polymer type, for the purpose of allowing efficient separation of different polymer types for recycling. Ask students to help you design an experiment to see if the speed of water molecules is different in hot water compared to cold water. Answer the questions in the table below about this molecule polar. On heating or cooling most polymers undergo thermal transitions that provide insight into their morphology. Can anybody help me name it? A: Click to see the answer. What does the 2 mean in the formula 5Mg3(PO4)2?

Determine and name the longest continuous carbon chain…. Students may guess that molecules in hot water move faster. Pure cellulose, in the form of cotton, is a soft flexible fiber, essentially unchanged by variations in temperature ranging from -70 to 80º C. Cotton absorbs water readily, but is unaffected by immersion in toluene or most other organic solvents. Students add food coloring to hot and cold water to see whether heating or cooling affects the speed of water molecules. Although polymers of this kind might be considered to be alternating copolymers, the repeating monomeric unit is usually defined as a combined moiety. These pack together easily in crystalline domains that alternate with amorphous segments, and the resulting material, while relatively strong and stiff, retains a degree of flexibility. They show the number of each type of atom in a molecule. Q: For each system listed in the first column of the table below, decide (if possible) whether the…. How many unique carbon….

Q: Building your OWN molecule Use the molecular model kits OR the Phet Simulator…. The latter is particularly attractive since a majority of plastics are made from petroleum, a diminishing resource with a volatile price. Despite use of the recycling symbol in the coding of plastics, there is consumer confusion about which plastics are readily recyclable. Check all that show the elements that make up a compound. Derivatives of cellulose, such as cellulose acetate, have long served for the manufacture of films and fibers. The heat and chemical resistant O-rings used to seal sections of the solid booster rockets had an unfortunately high Tg near 0 ºC. Because of their high melting point and poor solubility in most solvents, Kevlar and Nomex proved to be a challenge, but this was eventually solved. Q: Write the molecular formula for the compound that exhibits a molecular ion at M* = 96.

Students should realize that since the molecules in hot water are moving faster than in cold or room-temperature water, they should draw more motion lines. And access revision papers with marking schemes, video lessons and live classes. The solution is heated until all…. Have students fill in the blank with the word increases or decreases on their activity sheet as you read each sentence. A: Primary amine react with unsaturated ketone to form beta - amino ketone. It is sometimes interpreted as the temperature above which significant portions of polymer chains are able to slide past each other in response to an applied force.

The following problems focus on concepts and facts associated with the treatment of polymer chemistry in this text. The glycoside linkages in polysaccharides and the ester groups in polyesters represent points of attack by the enzymes of microorganisms that facilitate their decomposition. Many polymers, both addition and condensation, are used as fibers The chief methods of spinning synthetic polymers into fibers are from melts or viscous solutions. The terminal functional groups on a chain remain active, so that groups of shorter chains combine into longer chains in the late stages of polymerization. Due to the chiral nature of lactic acid, several distinct forms of polylactide exist. Because polymer molecules are so large, they generally pack together in a non-uniform fashion, with ordered or crystalline-like regions mixed together with disordered or amorphous domains. CH₂OH CH2OH ОН ОН O OH ОН ОН They are the…. However, nature often has a way of rewarding such success by exposing unexpected problems generated "outside the box" of the defined project. PLLA has a crystallinity of around 37%, a glass transition temperature between 50-80 ºC and a melting temperature between 173-178 ºC. Students will be able to explain, on the molecular level, that heating and cooling affect molecular motion.

As the name implies, this reaction moves a carbon radical from one location to another by an intermolecular or intramolecular hydrogen atom transfer (colored green). These reactions are illustrated by the following equations. Blue food coloring in a small cup.
