Problem 13

Explain how a molecular equation, a complete ionic equation, and a net ionic equation differ

Step-by-Step Solution:
Step 1 of 3

Chemistry Lecture Notes 11/15/16 Polymers Plastic, foam, nylon Large chain molecules made up of monomers (smaller molecules) We use plastic rather than glass bottles today (safer, require less materials) Glass is heavier and would cost more to transfer Recycled water bottles do not get reused for food grade plastic Plastic materials can be made to flow under heat and pressure (plasticity, ability to change shape) Natural Polymers Silk (we create synthetic substitute as well) Wool Starch (glucose monomers) ex. Pasta complex carb Wood (cellulose monomer) Protein (amino acid) DNA, RNA (nucleotides) Cotton (Cellulose) Synthetic Polymers Polyethylene (Ethylene-2 carbon w/ double bond+4 hydrogen) Ethylene derived from petroleum Synthesis: ethylene-US 20 billion kilograms, produced from cracking petroleum, a gas, put under heat, pressure, and catalyst to create a very long chain Polymerization: Formation of Polymer Condensation polymerization-creates polymer, water, and waste-product/bi- product Condensation polymerization occurs when small molecules (water, alcohol, ammonia, HCL, are released as byproduct) Addition polymerization occurs when monomers add to one another in such a way that resulting molecule contains all atoms that are present in monomer If you change the type of monomer you change the type of plastic When you have more than one type of monomer it is called a copolymer The Big 6 Dictates recycling #s, so that like polymers go to the same place Polyethylene (LDPE) (HDPE)-low density (recycling #
