physical change - Answer A change that alters the form or appearance of a material but does not make the material into another substance. chemical change - Answer a change in which one or more substance combine or breaks apart to form new substances Reactant - Answer A substance that enters into a chemical reaction products - Answer A substance formed as a result of a chemical reaction precipitate - Answer A solid that forms a solution during a chemical reaction exothermic reaction - Answ...

exothermic reaction - Answer A reaction that releases energy in the form of heat endothermic reaction - Answer A reaction that ABSORBS energy in the form of heat enthalpy change - Answer the amount of energy absorbed or lost by a system as heat during a process at constant pressure...

Experiment 7: We examined 3 different types of polymerization 1. Condensation (interfacial polymerization) 2. Chain Addition 3. Cross-linked what did each accomplish? - Answer 1. Nylon-10,6 is made from sebacoyl chloride and hexamethylene diamine 2. Polystyrene is made from chain additon of styrene and the initiator as benzoyl peroxide which generates radicals with heat, these radicals react with the styrene to begin chain addition Experiment 7: Chain addition vs Condensation Polymerizat...
