Marissa Ware Partner(s): None Chem 253—TA: Josh Lovell Lab 1: Effect of pH on a Food Preservative 6/11/13 Purpose: (1 point) To determine whether a chemical change occurs when Sodium Benzoate is acidified to Benzoic Acid. Theory: (2 points) Sodium Benzoate is a common food preservative found in jellies‚ jams‚ sodas‚ fruit juices‚ etc... Its acid‚ Benzoic Acid‚ is an organic preservative that stops the growth of bacteria‚ yeasts‚ and molds. Reaction: (3 points) Reaction: sodium

and raise. Kahikina chooses to participate in this program because her doctor describes the program as “a true act of aloha” (Kneubuhl). What the state does in the end‚ which they do without Kahikina’s consent‚ is representative of the exploitation and policing of women’s bodies‚ especially the bodies of women of color and indigenous women‚ that has continued for centuries. To achieve a perfect postcolonial state‚ the state in Kneubuhl’s story just perpetuates the same harmful practices. Kneubuhl’s

pH indicators‚ in chemistry‚ are usually a weak acid or base that are naturally occurring in various plants and flowers and can act as dyes. Some examples of indicators are Litmus (Comes from a plant species called a lichen)‚ Phenolphthalein‚ Thymol blue‚ Bromocresol green and Universal indicator. All these indicators have a certain turning point in color once a certain concentration equilibrium of Hydrogen cations in reached (H +) or a certain concentration equilibrium of H3O+(Also OH - using Arrhenius

Ho Chi Minh: Puppet or Leader? United States presidents from Harry Truman to Richard Nixon were wrong to think that Ho Chi Minh and his followers were "puppets" to the Soviet Union or Chinese Communist. Many policies the Presidents made throughout the war proved that they never tried to see Ho Chi Minh as anything else but communist and were convinced that they had to do everything and anything to stop him from gaining any control over the country of Vietnam. The Vietnam War‚ specifically

Introduction: The purpose of this experiment is to test if altering the pH of the milk will trigger a hydrophobic reaction. It will also give me a better understanding of the scientific method‚ hydrophobic reactions‚ and how pH affects substances. If the vinegar and salt are added to the heated milk‚ then the milk will curdle. I came to this conclusion based on common knowledge and the text introducing the experiment. I have not made cheese at home before‚ but I have made Hamburger Helper meals

Investigation into how pH levels affect Catalase activity in potato samples – (enzymes) Introduction: The aim of this investigation is to understand and monitor the effects pH levels have on catalase activity within controlled potato samples. Catalase is a type of enzyme that is found widespread among organisms that grow in the presence of oxygen (almost all living things) its specific use is to speed up the decomposition of Hydrogen peroxide (H2O2) within cells. Hydrogen peroxide is a bi-product

"Bros Before Hos": The Guy Code In “Bros Before Hos”: The Guy Code‚ Michael Kimmel discusses the ways that today’s society expects guys (males between the ages of 16 and 26) to behave. He spends a lot of time on “Guy Code‚” a list of values that all men are supposed to have that have been summarized by Robert Brannon‚ a social psychologist of the 1970s. The first rule is “No Sissy Stuff‚” meaning that guys shouldn’t show their feelings‚ and if they do it is considered a sign of weakness. The
