Organometallic chemistry

The results found in the collated table supports the hypothesis, however, it was not as accurate as expected. From observation of the collated results, it can be seen that the greatest froth volume is found at 30oC, rather than the predicted optimum temperature of 39oC. Errors within the individual group results, concluded that the both 10oC and 20oC were wrong due to the vast froth volumes. For a smaller amount of catalase, this would result in a smaller froth volume, conversely, with a greater…

Discussion: In sample, B there was 16% salt, which is unnaturally higher than the global average of 3.5%. When I asked about the reason of this, I found that the water was artificially created. This was also the case of Sample, A which had 9% of salt. That is about 3x the amount of salt from the global average. All though this is not an experiment with data, that we can apply to real life, it was still great fun to do the experiment and the lessons I learnt will stick with me for a long time.…

ETHICS APPLICATION FORM - Ultrasound imaging of trained and untrained muscles 1. DESCRIBE THE BASIC PURPOSES OF THE PROPOSED RESEARCH. If a person gets paralyzed and cannot move certain muscles, those muscles tend to change structure and get weaker. It would be useful to have a method of seeing what condition the muscle is in order to rehabilitate the person effectively as well as using that method to help clinical diagnosis of ailments known to cause muscle degradation. The basic purpose of…

unique history are three phrases that describe many things. However, all three combined only seem to describe Birthstones. Birthstones are amazing objects that affect our economy in many ways. More importantly, birthstones have a deep connection to chemistry and science. Due to their chemical properties, birthstones can also be used for medicinal purposes and healing techniques that have helped humans throughout time. Overall, birthstones contain many disciplines and the concept is one of the…

A different type of Japanese bamboo had been studied by Phong et al. (2012). Moso bamboo was harvested and processed using several methods to obtain the fiber. In alkali extraction method, the bamboo was cut into thin slabs with length and thickness of 25 cm and 3 mm, respectively. The slabs were immersed in different concentration NaOH solution (1%, 2%, 3%) at 70 ⁰C for 10 h. This study showed that only 1% NaOH resulted in higher mechanical properties. The roller looser was then used to produce…

Discussion For the first part of the experiment, a solubility test was conducted on all compounds. Because they were all ionic, every known compound naturally dissolved in water, and conducted electricity. As the next determining factor in the process to identify the unknown substance, the compounds were tested in acetone. As seen in table 2, only one compound, Ca(NO3)2 was found to be soluble in this solvent. Because the unknown solid was insoluble in acetone, Ca(NO3)2 was then eliminated as a…

I’m contacting you about the concentrations of the two copper (II) sulfate solutions that you were unable to correctly identify. The good news is that, for both samples, we were able to accurately determine their concentrations using Beer’s Law, a well-established law that governs the relationship between a solution’s concentration and the amount of wavelength the solution can absorb under standard conditions. Before going any further, though, let me fill you in on some of procedures and…

Discussion of Results and Scientific Explanation To achieve the goal of determining an unknown acid or base, anion and cation test were performed. These tests allowed for the components of the solutions to be identified, therefore, achieve the second goal. The pH was also used in to help find the identity of the unknown solutions and it was used to draw conclusions about the solutions. Dilutions were used to help understand the different behaviors of different concentrations. Household items…

The NASA Antares Rocket exploded out of the air, after it was clearly safe to launch. 5,000 pounds of supplies and more than 200 million dollars were wasted. Heading to the space station on the rocket were several experiments given by the Chinese, Russians, Americans, and Australians. They were supposed to be tested in space to examine their effects in space however, after the explosion, the experiments need to be returned back to each country accordingly. The Chinese will get LB (mineral oil),…

by which various chemical substances combined with each other could be explained nicely if one assumed that chemical combination was the group together of atoms possessed of definite weights” (Chang 135). Thomas Thomson wrote in his history of chemistry “the atomic theory first occurred to Dalton during investigations of olefiant gas and carbureted hydrogen gas…Dalton found that if the amount of carbon was the same in each compound, then carburetted hydrogen gas contains exactly twice as much…
