ABSTARCT In this experiment I have compared three different methods of determining the amount (percentage) of ethanol present in an aqueous sample. I tested three different samples containing different percentage amounts of ethanol in them; Listerine, Terra Fresca Wine and the last is a mixture of ethanol and water that was made by me. The three different methods compared are the redox titration method which involves the oxidation of ethanol to ethanoic acid and then titrating the residue with…

Geography of “Stuff” March 1st Leila Chapa Geography-140-001 Dr. Joni Palmer As markets grow worldwide, the pressure on natural resources continues to grow as well. This is causing many companies to look at different ways of developing their product. For many producers, by just looking at the life cycle of their product, they learn that they can reduce operating costs, including lowering their energy consumption and raw material use. Recycling alone does not look at the big…

Fossil Fuels are organic deposits derived from decaying plants and animals that have been fossilized over millions of years. There is more to them than that however they are also hydrocarbons comprised primarily of the following elements: carbon and hydrogen and some sulfur, nitrogen, oxygen, and minerals. Different combinations of these elements are used as a fuel for our everyday lives. This paper’s purpose is to explain some of the chemistry behind the use of these various fossil fuels as…

Introduction: This article provides a brief summary of existing articles H_2 Storage on single and multi-walled carbon nanotubes by Gerasimos E.Ioannatos,Xenophon E.Verykios. And Hydrogen storage in carbon nanotubes revisited written by Chang Liu,Yong Chen, Cheng-Zhang Wu,Shi-Tao Xu,Hui-Ming Cheng. These articles discusses the hydrogen storage aspect in single walled and multiwalled carbon nanotubes. The first article discusses the adsorption of hydrogen on SWCNT and MWCNT at certain…

The intent of this experiment was to successfully transform synechocystis to a psbC lacking species through double homologous recombination. Subsequently we intended to retransform the mutated colonies back to the psbC carrying species after kanamycin selection. The initial knockout of the psbC gene ensured that photosystem II wouldn’t work and the colonies would rely on glucose as a source of sustainable nutrition. The sequential addition of kanamycin killed off the species that lacked the KanR…

Food is a chemical and all cooking is chemistry. It is a mixture of many different chemical components. It is one of the essential things of every living being. Worldly, interest in food science have increased in recent years because of increasing awareness of vital role of food in the health, well-being and economics status of individuals and nations people’s curiosity of trying new and different dishes. Although using chemicals in the food provides good taste and texture, sometimes adding…

To study the tolerability of the analgesic autoinjector in the non-rodents( rabbit) by analysing biochemical parameters. 8.1 Introduction The objective of drug discovery and drug delivery system is to treat infections and particularly pain and suffering during the ailments and thereby maintaining a healthy human population. Any development in medical field is evaluated using a variety of clinical procedures prior introducing to humans. In pharmacological research, animal usage has become a…

1. Discuss how the measurements in Part I (Small Things) relate to the terms accuracy and precision. 2. What is the width of a single DNA molecule in units of centimeters? [The width of the DNA molecule is given by the distance between any two phosphorus atoms recorded in Part II.] 3. Based on your answer to (2), how many DNA molecules would fit across the smallest dimension of the smallest item (from Part I) measured in lab? Write the number in scientific notation. 4. Using the…

Ever since the begging of time the medical practice has been in a fight with infections and disease control. From the early era of hospitals patients were at times in the same bed as another patient, thus spreading disease from one to another. A Hungarian obestritician by the name of Ignaz Semmelweis found and adovacted on the importance of hand washing. However, it was not until a physician by the name of Joseph Lister who created a spray to use while conducting surgery, thus being…
