ORGANIC MACROMOLECULES 1. What is a polymer? 2. Man-made polymers have been studied since 1832. Today‚ the polymer industry has grown to be larger than the aluminum‚ copper and steel industries combined. Polymers already have a range of applications that far exceeds that of any other class of material available to man. Give examples where polymers are applied in each of these categories: a) Agriculture b) Medicine c) Consumer Science

the reaction rate. This will result in the particles colliding more frequently and increasing the speed of the reaction. Also when they have more energy there will be more chance of the collisions being successful because the activation energy will be attainable. Hypothesis: In a reaction between calcium carbonate and hydrochloric acid‚ the products calcium chloride‚ carbon dioxide and water are formed. I predict that the higher temperature of HCl acid‚ the higher the reaction rate will be‚ this

To prevent gasoline prices from having devastating effects on the economy it has been proposed that all gasoline prices in the United States be fixed at the average price for the last two years. For simplicity it will be assumed that this price is $2.50 per gallon. When equilibrium prices are under $2.50 per gallon the excess payments will be kept in a government fund. When retail prices exceed $2.50 per gallon money from this fund will be distributed to pay the difference. Do you think that this

Do Gas Stations cause soil pollution? Soils are extremely important parts of every ecosystem. They are a home to many microbes and provide vital nutrients to the plants that live in them. pH is the measure of acidity or alkalinity of a solution‚ and most organisms have a very small range of pH values in which they can survive. 7 is considered neutral‚ lower than 7 is acidic (lemon juice‚ rain water) and above 7 is basic (bleach‚ soap). Lots of urban areas are dependent on car transportation‚

Exhaust Gas Recirculation 1. INTRODUCTION All internal combustion engines generate power by creating explosions using fuel and air. These explosions occur inside the engine’s cylinders and push the pistons down‚ which turns the crankshaft. Some of the power thus produced is used to prepare the cylinders for the next explosion by forcing the exhaust gases out of the cylinder‚ drawing in air (or fuel-air mixture in non-diesel engines)‚ and compressing the air or fuel-air mixture before the fuel is
