The results from these three major analyses helped to draw the conclusion that the unknown is in fact [Co(NH3)6]Cl3. -2.0 Synthesis/Analysis of Cobalt-Amine-Halide Compund (Procedure 1‚ pgs 16-7)) A cobalt (III) amine halide compound was prepared by making a solution of cobalt (II) chloride hexahydrate and ammonium chloride (NH4Cl) to liberate the Co (II) in the solution. “Activated”

Unlike most coefficients in Physics‚ friction behaves differently depending on whether the object is at rest or at motion.

Rachel Bohnenberger Professor Van Doorn ENVS 150-002 27 April 2015 GMOs Lab Report Introduction As the population of Earth increases exponentially‚ so does the demand for more food. One of the solutions to the question of how more food can be produced is Genetically Modified Organisms‚ or GMOs. There is an ongoing debate about whether or not GMOs are more beneficial or harmful to society. Some of the benefits to GMOs are: growing plants‚ such as corn‚ that are resistant to weeds and pests‚ larger

Osmosis Lab Report Hypothesis: Osmosis will occur when there is an uneven distribution of solute in a solvent. The higher the solute in solvent‚ then there will be a higher rate of osmosis through the diffusion gradient forming a hypertonic or hypotonic solution. Solvent with equal or no solute forms an isotonic solution. Materials: Distilled water‚ sucrose‚ dialysis tubing‚ string‚ 250 ml beaker. Procedure: To demonstrate and isotonic solution we needed 3 inches of dialysis tubing. We

go through the whole process of osmosis. Also‚ a lot of the experiment was rushed as we were under pressure to finish as quickly as possible. Unfortunately the time constraint was caused by and outside influence unrelated to the lab itself‚ and so next time we could do a lab under normal conditions where there are no outside disturbances. There were weight differences in the potatoes which could have caused thicker potatoes to absorb more than others. It was a little impossible to obtain the same

Synthesis of Tetraphenylcylopentadienone Post-Lab Report Purpose- This experiment illustrates the use of adol condensation for the synthesis of a five-membered carbocylic ring. It is also a good demonstration of the impact extended conjugation has on the absorption of visible light. The reactants are bright yellow in color while the products are a very deep purple color appearing almost black. Introduction- The synthesis of Tetraphanylcyclopentadienone was a further example of the adol

Alhia Harris October 18‚ 2011 Biology Lab report Proteins are very important throughout the body. They have a lot of functions in cells. Antibodies are proteins that help cells rebuild the cells when they are destroyed. Transport proteins move substances from one place to another. Regulatory proteins control cellular metabolism in a way that cells throughout the body can have the right amount of glucose in the blood. A common protein is an enzyme; in cells they speed up chemical reactions. For

The main purpose of this lab was to prove the laws of Ohm and Kirchhoff. On another note‚ being able to take part in this lab taught my partner and I the fundamental skills of constructing series and parallel circuit and using a multimeter to calculate the current and voltage of a circuit. I believe that if we only have the

economy: TAX: Since 99% of H&M´s garments are produced outside of Sweden‚ and they claim that “H&M sees tax as an important part of its social responsibility”‚ it´s hard to understand why the company does not redistribute any profit to the producing countries. H&M avoid paying income tax in sourcing markets by coordinating all their procurement orders through representative (procurement) offices in the producing countries. According to Erik Knijnenburg‚ the Global Tax Manager of H&M‚ there is no commercial

The concept is very similar to sudden expansion in pipe flow‚ except that hydraulic jumps occur in open-channel flow. At
