The diagram below depicts a system of aqueducts that originate at three rivers (nodes R1‚ R2 and R3) and terminate at a major city (node T) where the other nodes are junction points in the system. Using units of thousands of acre feet‚ the tables below show the maximum amount of water that can be pumped through each aqueduct per day and the following diagram shows the network of the system.

Atausch July 28‚ 2014 Bio 102 Lab Final Exam: Acids and Enzymatic Reaction Purpose: To examine how an acidic fluid will modify the outcome of an enzymatic reaction. Introduction: Enzymes are “specialized proteins made by living cells that serve as biological catalysts.” (eScience Labs‚ LLC‚ 2013) These enzymes “allow certain industrial processes to be carried out at normal temperatures and pressures‚ thereby reducing the amount of energy and expensive equipment needed.”(BBC‚ 2012) Enzymatic

KINETICS OF THE ACID DECOMPOSITION OF THIOSULFATE Aqueous solutions of thiosulfate‚ S2O32-(aq) are stable if neutral or basic‚ but decompose quickly when the thiosulfate is dissolved in acid according to the equation: Sulfur dioxide is a gas at room temperature‚ but is very soluble in water. Sulfur‚ a water insoluble solid‚ forms a colloidal suspension. As a result‚ the solution first becomes cloudy and then opaque. We can take advantage of the developing opacity of the reaction system to do a

Lab 5 Acid/Base Extractions Introduction The purpose of this experiment is to separate either the organic base (amine) or organic acid (carboxylic acid) from a mixture that contains inorganic impurities (salt) by performing a liquid-liquid extraction and then taking a melting point. Key Experimental Details and Observations Our starting material‚ Compound B‚ was a fine white powder and weighed 0.535g. The final product was a shiny white sheet that resembled acrylic paint and weighed 0.109g

Acid Rain Webquest Name: ________Jacob Rough_________________________ Date: _____3/25/13________ Sulfur dioxide and nitrogen oxides are gases released by the burning of fossil fuels. These gases can react with water and oxygen to form acids. Normally‚ rainwater is slightly acidic. But the additional acid that enters the air when fuels are burned makes it even more acidic. Acid rain can have a harmful effect on fish and other wildlife and upsets the delicate balance
