sharpens their own characteristics. In the story “Astronomers Wife” we see a strong foil between two of the characters because of the protagonist‚ Mrs. Ames‚ who describes both men in very different views through their attitudes towards people‚ work ethics and their different intelligentsia. Another way that Mrs. Ames differs the plumber and Mrs. Ames husband is how they treat her. Mr. Ames is a person who seems to treat people as an object rather than an actual human being‚ especially

In class we decided that the rate of a reaction increases when there are more collisions or when the activation energy is reduced. We then determined that there were four ways to increase the reaction rate: increase temperature‚ add a catalyst‚ increase surface area‚ and increase the concentration of reactants. The objective of this lab was to experimentally show how temperature and surface area impact the rate of reaction‚ so only two of these methods were tested. The evidence indicates that increasing

Aim: To determine the rate law of chemical reactions Introduction: The aqueous solution of potassium peroxydisulphate can oxidize potassium iodide as follow: Equation: K S 0 (aq) + 2KI (aq)->2K S0 (aq)+I (aq) 2 2 8 2 4 2 KI(aq) +I (aq) -> KI (aq) 2 3 _________________________________________________ K S 0 (aq) +3KI(aq) -> 2K S0 (aq)+ KI (aq) 2 2 8 2 4 2 The rate law of this reaction can be represented as follow: Rate=k[S208 2-]^a [I-]^b When the concentration of peroxydisulphate ions

1. Discuss a diagnostic pattern. Explain how to determine reading potential. There is no single correct method for teaching a student how to read. A teacher must try all methods until they find what works best for that child. Throughout this time‚ a teacher must use a diagnostic pattern to prevent difficulties in learning to read as well as how to improve a student’s reading so that they can reach their potential for reading. There are two parts to the diagnostic pattern. The first is identification

A Distant Mirror: The “Calamitous” 14th Century Barbara Tuchman’s A Distant Mirror is about as entertaining as a history book can get or should be. Tuchman is a captivating storyteller and the quality of her history of France in the 14th century speaks for itself as the book has remained in print after 25 years. Famous for her engaging‚ narrative style that makes history flow like a thrilling novel‚ Tuchman presents a comprehensive review of 14th century Europe (via France‚ the dominant European

Life events can determine your destiny‚ but sometimes your destiny doesn’t turn out the way you would like. An example of this is in the T.V. series The Flash. There is a man named Hunter Zolomon. As a kid his father murdered his mother right in front of him. Then you fast forward and he literally becomes a speed demon. And he did everything he could to go faster and faster will killing everyone in his path. Either way he went on the bad path because of his life events. When i was in kindergarten

The effect on rate of an enzyme catalysed reaction by different objectives which include effect of substrate‚ temperature‚ ph and effect of a competitive inhibitor phosphate ions. This is determined by the reaction of hydrolysis by p-nitrophenylphosphate (PNP) as a substrate by the enzyme phosphatase. Abstract The hydrolysis of p-nitrophenyl phosphate has been studied in human red blood cells. To see if hydrolysis was related to the functioning of the sodium pump. Acid phosphatase catalysis’s

Abstract: This lab tests how temperature and pH affect how enzymes will function. The lab showed that temperature will denature an enzyme when past its optimal working temperature and won’t denature in cold temperatures‚ but have slowed molecular activity. pH will also have an affect on an enzymes efficiency‚ when out of optimal pH the enzyme will not function as it is supposed to and if to far out of the optimal pH the enzyme will change shape and no longer work. Enzymes also showed to be reusable

produced the most oxygen of all three trials. Heat tends to increase the rate of chemical reactions‚ explained in the article Temperature Effects (Introduction to Enzymes) by Chris Jamison. “Like most chemical reactions‚ the rate of an enzyme-catalyzed reaction increases as the temperature is raised. A ten degree rise in temperature will increase the activity of most enzymes by 50 to 100% . Variations in reaction temperature as small as 1 or 2 degrees
