methylated form of vitamin B12, Introduction: Using Co(I)Cl2 as a starting material, it is possible to produce a cyano(pyridine)cobaloxime like compound, Chloro(pyridine)cobaloxime whose chemistry can be investigated via means of methylation, as such using the Chloro(pyridine)cobaloxime as a model for replicating chemistry already known of cyano(pyridine)cobaloxime. These various Models for Vitamin B12 (right) all pivot on the known data that the octahedral cobalt central atom and it’s…

characterized as the branch of chemistry concerned about the three-dimensional course of action of particles and atoms and the impact of this on concoction responses. A critical branch of stereochemistry is the investigation of chiral atoms. Stereochemistry is otherwise called 3D science in light of the fact that the prefix "stereo-" signifies "three-dimensionality". The primary investigation of stereochemistry is on stereoisomers and traverses the whole range of natural, inorganic, organic,…

A small burette funnel was filled with column packing solvent at mobile phase, high boiling petroleum, in this case hexane (and then 10%acetone hexane mixture), and Alumina as stationary phase. When adding the sand and the alumina they have to be first mixed with the hexanes in order not to disturb the column. The Lycopene is Red- Orange and more attracted to alumina due to its high degree of Unsaturation, which can be expected to be eluted after Yellow-Orange Carotene pigments. And the other…

balloon rides, a nationwide push for the metric system, bigotry charges, and student protests. This was the Mendeleev that Russia knew and (mostly) loved. The periodic table was just a particularly prescient project tucked away in an introductory chemistry textbook, widely known to the scientific community…

Kyle Rohl Chem 3520 Nobel Prize Paper Chemicals in 3D Vision The Nobel Prize in Organic Chemistry for the discovery of chemicals in 3D vision was awarded to Derek Barton and Odd Hassel in 1969. This was the breakthrough in visualizing the way chemicals could be interpreted. Before their phenomenal discovery, people could only think of seeing a chemical such as cyclohexane in its planar, flat, 2D form. What Barton and Hassel found that was different from the universal perspective of this…

How the changing mass of solute effects the heat given out when dissolved in water Aim To investigate how the changing mass of a solute will affect the energy given out. Introduction Dissolving is when a solute is mixed into a solvent to form a solution. Dissolving can be either endothermic or exothermic. Endothermic reactions happen when the energy given out when bonds are broken, is greater than the energy given out when bonds are made. As more energy is used and taken in, the surroundings…

The purpose of this experiment is to observe the difference between ionic and molecular compounds using conductivity as a means of analysis. This lab will allow us to organize compounds based on the magnitude of their conductivity. This will allow us to determine whether or not a compound is molecular or ionic based on its conductivity. This lab also will determine the effect of concentration on conductivity of certain electrolytes, as well as the number of ions. We also will examine the effect…

dangerous situations, even though they are not proven to increase our probability of a specified event. George Gmelch and Richard Felsen released an article pertaining this subject. The article, entitled “Can a Lucky Charm Get You Through Organic Chemistry”, gave the general public a somewhat easy-to-read article, which provided an experimental result about how many people believe in magic and what they believe about it. By analyzing the article, it can be seen that the experiment covered…

THE EFFECTS OF OSMOSIS INTRODUCTION Osmosis is the process where molecules of a solvent are prone to pass through a semi-permeable membrane, going from a less concentrated solution to a higher concentrated solution. Doing this equalizes the concentrations on both sides of the membrane. Our question throughout the experiment was; What effects do the different concentrations of sucrose have on the rate of osmosis? The hypothesis was; If the solute concentrations do effect the rate of osmosis,…

The experiment was done to reveal how workouts supplements like C4 can affect the development of humans. Other experiments like this one can also be used to show how some substances may affect the development of humans. In the experiment the independent variable was the amount of the C4 that was placed into each well in the experiment, and the dependent variable was the zebrafish embryos after they were exposed to the C4. In addition, 2 controls were set up, containing a ocean/embryo solution…
