THE EFFECT OF HYDROGEN BONDING ON RESISTING FLOW Design Investigating a factor affecting the viscosity of a mixture of liquid Research Question The effect of hydrogen bonding on resisting flow of five different liquids Background Theory Viscosity is the resistance of a fluid to flow‚ either within itself‚ or to moving past an objects moving through it. A liquid with high viscosity is thick and flows slowly. A liquid with a low viscosity is thin and flows quickly. Different liquids

The hypothesis If a chemical reaction occurs‚ then there will be indicators of a chemical change‚ was supported throughout this experiment. Throughout this experiment there were several reactions that took place‚ and an indicator of such chemical reactions could be seen throughout each one. The first piece of identifiable evidence was present in the first step‚ which was when copper (II) nitrate and sodium hydroxide were combined. When stirred‚ a blue precipitate formed at the bottom of the test

Experiment 3: Wittig Reaction Introduction This experiment performs a modified Wittig reaction using a phosphorus-containing Hornes-Emmons-Wittig reagent to generate an enolate anion of trimethyl phosphonoacetate instead of a phosphorus ylide. The methyl trans-4-methoxy cinnamate produced is then analyzed using melting point and 1H NMR spectroscopy. Theory The Wittig reaction prepares alkenes from carbonyl compounds by attacking a phosphorus ylide with a nucleophilic carbon atom stabilized by

Discuss why hydrogen bonding is essential for life Throughout biochemistry there are many bonds without which life as it is on earth today would not be possible. One of the most important bonds of these is the hydrogen bond‚ a weak chemical bond that is present in essential biological molecules such as water and polypeptides. A hydrogen bond is defined by Campbell and Reece as occurring when a hydrogen atom is covalently bonded to an electronegative atom but attracted to another electronegative

Title: The affects of hydrogen peroxide on catalase reactions in animal and plant cells at different temperatures and states. Introduction: All living organisms in the kingdoms of life are composed of and depend on cells to function normally. Not all cells‚ however‚ are alike. There are two primary types of cells: eukaryotic and prokaryotic cells. Cells contain organelles‚ or tiny cellular structures‚ that carry out specific functions necessary for normal cellular operation. (Regina Bailey Updated
