Reaction (1) How to make Sodium Azo-Tetrazolate--Pentahydrate (SAT) Approximately 2.15 g of Aminotetrazolate monohydrate was added to approximately 62.5 ml of 2 M sodium hydroxide. While being stirred, the solution was heated, increasing its temperature up 10 degrees Celsius, up to 60 degrees Celsius. Over a one hour time period, potassium permanganate (an amount of 2.5 g) was added in increments. After this, sodium sulfite was added at a slow pace, and powerful stirring destroyed the…

containing assay buffer mixed with with the electron inhibitor sodium azide and the artificial electron acceptor DCIP, and SDH’s substrate, succinate, were prepared. When the saved cell fractionates stored on ice were added to the prepared room temperature solutions, the color change of the solution due to the reduction of DCIP was immediately measured using a spectrometer. Measurements were then taken two more time in seven minute increments. The amount of reduction of DCIP as measured by the…

a great difference in the rate of transpiration between the cold water and water at room temperature. The results in the experiment indicate that cold water transpires at a faster rate than water at room temperature. The results were measured from 0 to 30 minutes. At the fifteen minute mark the transpiration rate for both differed slightly. In trial two and three, the results for the water at room temperature were still at 0ml, and the first trial had gone up by 0.01ml. Therefore nothing much…

hundred degrees Celsius, relative to its small molecular weight at roughly eighteen grams. Water requires more energy to break hydrogen bonds before it can boil. Freezing works the same way as boiling, but in reverse since it is going to colder temperatures, zero degrees Celsius to freeze, rather than hotter. These extremes in freezing and boiling points allow the molecules to freeze or boil very slowly. Another unique property of water is surface tension. Aside from mercury, water has the…

Paragraph 1 This paper talks about how the crystal structure of FePO4will change at different ranges of temperatures. FePO4 has a crystal structure which is similar to quartz, which is made up of 2 phases at different temperatures. At low temperature, FePO4 will demonstrate α phase till the transition temperature of 980K before demonstrating the β phase. Space group of α phase FePO4 is said to be P3121, thus suggesting it has a trigonal structure. As for β phase FePO4, the space group will be…

In this lab, an experiment was done in order to test how the abiotic factor of temperature affects a Tenebrio molitor’s activity level. Both experiments conducted consisted of two separate treatment trials; one in a warm environment (25 C) and one in a relatively cold environment (14 C). Results obtained from these experiments both showed a higher level of T. molitor activity in warmer environments as opposed to the cold environment where less activity occurred. In this case, the activity level…

of different alcohols at a different temperature. Producer: There will be two parts in this experiment to know the strength of the intermolecular forces of different liquids, to conclude the role of the molecular size and structure of the intermolecular forces. Part A: In the first part of the experiment, the temperature changes will by measuring by the liquids evaporation, and since it is an endothermic reaction, the temperature will decrease. The temperature probes will be connected, and…

heat. Specifically, I will be discussing conduction from the temperature outside of De smet and the temperature of my dorm room. The material that the energy will transfer through is the two large two-paned windows that are on each wall. I will complete example calculations by measuring the calculating the area of the windows and the temperature inside and outside. During the cold Spokane morning, my roommate and I care about the temperature in our room very much and prefer not to be freezing…

Paragraph 1 The crystal chemical relationship between quartz (SiO2) and FePO4 can be studied by putting them under a temperature range of 294K to 1073K in an attempt to study the evolution of their structures. In doing so, we would able to examine the other quartz homeotypes that emerge during high temperatures and known to show a-b transitions. This study of quartz homeotypes were essential because the new information that was gathered would aid greatly in the creation of new products and more…
