According to Regis, the reason why there were two layers is because the two compounds in the solution were immiscible. This means that they don’t dissolve each other. Therefore the aqueous solvent will sit on top and the solvent that is immiscible with water, the organic solvent, will sit on the bottom. The reason why the percent recovery wasn’t higher was because maybe not all of the upper aqueous layer or all of the organic layer was extracted all the way. If some of the upper layer was mixed…
industrial activity all increases the speed of water and also changes the hydrology of the wetlands. Louisiana has become a “sacrifice zone” for the countries’ energy…
In 1798, Thomas Malthus theorized that population growth was an impending danger that if not properly checked would result in an unfavorable outcome for human society. The main idea behind his theory was that the accelerated growth of the human population is unsustainable and that we are set to eventually outpace our ability to produce food, leading to a major catastrophe. Two hundred years later, Thomas Malthus’ theory fortunately has not come to fruition, however, it is still a major topic of…
General procedure: One equivalent of spacer was coupled using 2.4 equivalents of inhibitor, 0.18 equivalents of copper sulfate, 0.36 equivalents of (+)-sodium-L-ascorbate, in a mixture of 10% H2O in DMF, 24 mL/mmol spacer. The mixture was placed in the microwave for 30 minutes at 80oC Pro6 Spacer (10) (30 mg, 0.036 mmol) and 18 (36 mg, 0.087 mmol) were dissolved in 778 µL DMF. Copper sulfate (1.62 mg, 0.006 mmol) and sodium-L- ascorbate (2.57 mg, 0.013 mmol) were dissolved in 86 µL H2O. The two…
Powdered milk. Whole milk is the baseline comparison since it is the milk that has been tempered with the least. The 2% and 1% milks have had most of their fat removed. Powdered milk goes through an evaporator, removing most of its butterfat and ¾ of its water. Both 2% and 1% went through another process in which fat was removed from the milk after placing it into a “centrifugal separator” (Christine Gallory, 2015). Hypothesis: If different types of milk were to go through the curdling process,…
just fell off by themselves,” CoCo said slowly. “Oh! It must be the low total alkalinity level in the tank. Yeah, that must be the reason.” “Oh yeah, we can even feel it now,” all the other corals said in chorus. That afternoon, Jerry changed the water and added some bicarbonate salt to raise the alkalinity. Everything returned to normal—calm and…
excluding the Sucrose. So initially, the Solid here which is Sucrose will remain undissolved and will be collected through Vacuum Filtration. b. DCM is used to remove the impurities from the sucrose, because DCM is denser than water and that’s why when DCM is mixed in water, the DCM remains at the bottom of the beaker. Before the Aspirin is soluble in the DCM, the aqueous layer should be mixed thoroughly in order for the…
lang acoording to the size of it. In addition the temperature in Gobi Desert can reach well past 100 degrees fahrenheit wich is hot for me in my opinion hjot weather ma.kes my head hurt Besides the air in water has been evaporated... all the water that was there has been choked down into the water but sometimes when campers…
railings. The deck wrapped the entire back side of the house which is full of furniture, a table, and even a hammock. It has the perfect view of the lake which is located right in back of the house with a beautiful freshly cut green yard which meets the water.…
click to start, I hear sea-water lapping against the sea shore gently. The ocean sings a “ sha-la-la-la ” and there is no wind. All I can hear is the patting of water, clear and sweet-sounding. This kind of soundscape is usually a background sound, letting people think of a beautiful and romantic story happens against it. After that it comes the second type of ocean. The waves get bigger and the sound gets louder. The overall…
