5) Check them every 5 minutes and make observations. Results and Discussion I trialed this experiment three times because the cool water kept freezing before the boiled water. At first, I thought that the problem was with the lids-does it work better with the lids on of not? I came up with the same outcome on both of these trials- the cold water froze first. Then, I came up with a great idea.
When Part II ended, one cardinal problem was noticed. The lamp which provided the light was defective; it was more focused towards Beaker 2. This could be related to less accuracy of following results. The thermometer showed that in Part II, Beaker 1 with greenhouse gasses warmed slower than Beaker 2. Hence, Beaker 1 also cooled slower than Beaker 2.
Meaning that the more acidic to stable of the Hydrogen Ion concentration is the more soluble the bath bomb becomes. This data does not support the original hypothesis of “If bath bombs are designed with different concentrations, then the Sodium Bicarbonate bath bomb design will be the most soluble because Sodium Bicarbonate is a salt and has a high solubility in water.” The data showed that the citric acid and sodium carbonate mixture with an average pH of 6.4 disintegrated in 9 minutes and 19.44 seconds while the sodium carbonate took the longest time to disintegrate at 25 minutes and 27.69 seconds. So clearly the as stability of the Hydrogen Ion Concentration from an acidic solution, the less time the salt mixture takes to disintegrate but when the solution becomes basic the more time the salt mixture takes to
Moreover, in the high temperature oxidation of methane, the rate of the governing reaction CH4 + O2 CH3 + HO2 is much slower than of the similar reactions of the higher order alkanes . Therefore, the nonlinear promoting of DME addition on ignition is not observed for higher order alkanes at high
When the results for the first test tube were recorded, then the next solution/mixture was prepared. The second test tube was exactly the same as the first, the only difference being that the SPM was this time set to 35oC. The temperature of the SPM gets increased by 1oC for every test tube solution, until test tube 7 with an SPM temperature of 40oC. After all the absorbencies for the varying temperatures had been recorded – the product concentration of each test tube solution was calculated using the absorbency readings at 10 minutes for each respective test tube mixture. The product concentration was calculated using Beer-Lamberts’ law of A = ECL.
TLC was used to identify the actual unknown product as well as other products/reactants present in the filtered solution. The procedure was conducted by placing a TLC plate in a developing chamber that is filled with a small amount of solvent. The solvent cannot be too polar because it will cause spotted compounds on the TLC plate to rise up too fast, while a very non-polar solvent will not allow the spots to move. The polarity of the spots also determines how far it moves on the plate; non-polar spots are higher than polar ones. After spots on the TLC form, the Rf values are calculated and used to analyze the similarity of the compounds.
I think that this is because the company may have wanted miranda to be more gassy and put more carbon dioxide in or the acidic substance of oranges in miranda reacted stronger with the carbon dioxide. However there is a high possibility that our first test for miranda may have a couple of mistakes made since it was a large amount further than its other results(1st test: 3m, 2nd & 3rd test: 1.5m). This may be because we have shaken it too long, measured the results incorrectly, opened the can differently, changed the angle accidentally or since different people were shaking the can… Our method uses measuring distance to find out how well each soda propelled.Our strengths and limits in this method include many things. Strengths include it is accurately measuring the how well the gas and liquid has been propelled, is mostly safe and easy to gather results. The limitations include a large amount like: unable to tell which soda mark is which on the ground, not having the ability to know we are shaking at the same force, not having the most accurate measurer and tool, not able to stop at just the right time, not fully opening the
Oxidation is a process where an element loses electrons in a chemical reaction. These lost electrons travel into the copper in a process known as reduction. Reduction is a chemical reaction where an element gains electrons. Protons are also lost during this process, but protons cannot travel through the wire because they are very large in comparison to electrons. As a result, the protons remain in the electrolyte solution until the newly gained copper electrons pull them away from the electrolyte.
That factor was whether or not the trial used a rock sample. If it did use a rock sample, the time it took to drain the water would have been longer because the rock blocked the water from being drained, and therefore, delayed the draining time. If you look in the table, you can see all of the control test values are lower than the sample test values. However, it’s unclear as to why the outliers were not in the expected range. The values might have been influenced by a possible experimental error.
The Mycophenolate mofetil containing nanoparticle was constantly agitated during the dissolution test, collisions among MNP could first disintegrate the structure of the polymer layer. The subsequent fluidic shear devastated the particulate surfaces and caused the release of a drug. As indicated in (Table 7) the cumulative percentage of Mycophenolate mofetil released in the initial 2-4 hr was minor. This suggested that the current formulation could prevent the drugs from the initial burst release. As revealed in (figure 13), the rate of a drug released from MNP was pretty smooth.
