“If you prick us do we not bleed? If you tickle us do‚ we not laugh? If you poison us do‚ we not die? And if you wrong us shall we not revenge?” Shakespeare made it clear for all of us .he made it clear that revenge is a natural human reaction just like laughing when we are tickled or bleeding when we are pricked. In Ph.D. Karyn Hall’s Article Revenge: Will You Feel Better? She supports Shakespeare’s claim “Revenge seems to be one of the deepest instincts we have. Who hasn’t said‚ "I hope he gets

Consulting Chemists Institute Introduction The Consulting Chemists Institute was contracted by a local food manufacturer to determine if sodium benzoate‚ a common food preservative‚ undergoes significant chemical changes at the pH level encountered in the acidic environment of the stomach. Experimental Method Sodium benzoate was prepared by addition of an equimolar amount of aqueous sodium hydroxide (3 M‚ ~ 20 ml) to a benzoic acid (1.256 g‚ 10.3 mmol) /water mixture (10 ml). Benzoic

do: We will put potato pieces of similar sizes in to test tubes of different concentrations of sucrose solution‚ and measure any changes in mass and length. Affecting Factors: There are a number of factors which can affect our results. We need to keep them all the same‚ and make sure that the only thing that changes is the concentration of the sucrose solution. These factors include: • Starting length of potato • Volume of Sucrose solution • Temperature of potato • Temperature

We tested the Comparative pH ‚ Carbon Acid and Glucose content of different soft drinks. Since soft drinks like Coca-Cola‚ Royal and Sprite are common beverages that Filipinos like to drink‚ It is usually sold in a lot of stores and markets. (This beverages taste sweet and has a tangy feeling in your throat when drank.) Coca cola is a carbonated drink. Its content are Sucrose‚ Caffeine‚ Phosphoric Acid‚ Caramel color‚ and natural flavorings. We firstly tested the pH value of the different drinks

investigate about enzymes in potatoes reacting with Hydrogen Peroxide. In particular I will investigate the effects of changing the surface area of a potato when added to Hydrogen Peroxide. This is because‚ when increasing the surface area of the potatoes it will increase the rate of reaction because there will be more surface area on which particles from the potato and the Hydrogen Peroxide will collide on‚ and with more surface area there would be more particles carrying kinetic energy‚ and by carrying

monoprotic acids were determined with the aid of a buffer and pH meter. Experiment: This experiment was performed according to the procedures as provided in the Chemistry 111B laboratory manual: Po‚ Henry and Senozan‚ N. "General Chemistry Experiments Chemistry 111B"‚ 8th Ed.‚ 2004 Hayden-McNeil Publishing‚ pp 80-88. To determine the dissociation constants of weak monoprotic acids (HX and HY)‚ a buffer was needed to calibrate the pH meter. According to the manual‚ all four solutions to the experiments

Solution for Chapter 2 Exercise 5a 5. a. Draw the hierarchy chart and then plan the logic for a program for the sales manager of The Couch Potato Furniture Company. The manager needs a program to determine the profit on any item sold. Input includes the wholesale price and retail price for an item. The output is the item’s profit‚ which is the retail price minus the wholesale price. Use three modules. The main program declares global variables and calls housekeeping‚ detail‚ and end-of-job

Interprofessional Studies. With reference to acid-base balance explore the role of the respiratory system in maintaining blood pH? ‘We live and die at the cellular level’ (Reid‚ 2011). Homeostasis is crucial for normal cellular function. Acid-base homeostasis is the part of human homeostasis and refers to the balance between the production and elimination of H+ hydrogen ions (pH) within the body fluids (William‚ Simpkins‚ 2001‚ p.236). Metabolic reactions within the cells often produce a huge excess

the relationship between enzymatic reaction affected by temperature and pH. Through the testing the enzyme at different temperatures‚ and different pH levels; it would determine at which temperature and pH level the enzyme worked the most efficiently. Analyzing absorbance of the solutions with spectrophotometery will determine the reaction rate. To test the optimal pH‚ the starch and a buffer were combined at a specific pH level and tested the absorbance of a solution at various times. To resolve
