Basicity of Pyridine vs Pyrrole The lower the pKb value of a compound, the stronger a base it is. Since pyridine has a lower pKb value, it is a stronger base than pyrrole. In this example, we cannot use either the steric factor or inductive factor to explain their basicity. Instead, we have to look at the hybridization state of the respective nitrogen atoms. The nitrogen atoms in pyrrole and pyridine are sp2 hybridized because they satisfy the following two conditions: 1) the atom has at least…

The mission statement of the organization reads, "Partnering with parents and community, we provide a strong educational foundation to prepare children for future success." Ninety five percent population served is Hispanic. About 80% staff serving children and families directly is Hispanic. Administration consists of a CEO, a CFO, and ten directors. There is not enough diversity reflected in administrative team regarding gender, race, competencies, and education, although, most of the directors…

The earliest stone tool, created in Ethiopia 2.33 mya , marked the beginning of the struggle for control within mankind (Kimbel and Johanson 449). Born with an innate knowledge, and from “the beginning […], knowing almost nothing” (Arcadia,1.4. 47), human beings’ blissful ignorance of reality limits knowledge. With the opportunity to discover new knowledge one is able to gain experience from both the self and the universe. Tom Stoppard’s Arcadia, is a colourful comedy with dreary undertones.…

Discussion: Recrystallisation was performed to purify the "[Ni" ("O,O '-ONO" )_"2" ("N,N,N ',N '-tetrameen" )"]" product. These green powder extracted from filtration was prone to impurities such as unreacted "[" "K" _"4" ["Ni" ("N-N" "O" _"2" )_"6" ]"." "H" _"2" "O" and "KN" "O" _"2" . As the product was dissolved in hot ethanol solvent and slowly cooled to crystallise, the impurities would remain dissolved rather than being solidified. Thus, the different solubilities of the green…

Plot- Housekeeping is purely based on the lives of two sisters living within an isolated town. The protagonist Ruthie and her younger sister, Lucille, must endure various scenarios throughout their life. Their grandfather, Edmund, who works in the railroad industry is killed in a tragic accident as the locomotive slips off the tracks. Searchers are unable to find any remnants of human life.

The question of what consciousness is or what we can deem as to be conscious is most fiercely debated topic in this dissertation because its subjective nature; what you and I may consider to have its own consciousness may possibly or rather probably will be different, how then can we build a machine with its own conscience when we has humans still haven’t figured it what it even really means to be conscious. I think therefore I am This very famous statement written by French mathematician and…

Since the dawn of ancient civilization, humans have looked toward authority. The ancient peoples of the world’s river valleys formed the first cities, settling along the fertile banks. At their head, these cities had a leader, often one who had, or who controlled, the food supply. More often than not, the leaders of these cities claimed an ancient form of divine mandate. Their authority was second to none, and their authority resonated throughout the people they ruled. The ancient city of Uruk,…

Nevertheless, the existence of dark matter has been widely accepted henceforth, and research into it is ongoing. Astronomers have recently discovered a galaxy without the existence of dark matter(Shelton). Dark matter cannot actually be seen or detected itself, but, as Zwicky found, it causes immense levels of gravity. This newly discovered galaxy has only the normal amount of gravity you would expect to find due to its stars, planets, and general cosmic junk, unlike every other galaxy we’ve…

Measuring the Average Catalase Reaction Times of Solanum tuberosum Supernant in Hydrogen Peroxide Julie Fitzgerald Delano Woods Biology 103: Botany Professor Silady, Smith February 23, 2017 INTRODUCTION This investigation is geared towards observing the enzyme reaction times in Solanum tuberosum, also known as the common potato, depending on the temperature of the catalase. During the lab, students tested the reaction times of the catalase when placed in hydrogen peroxide when the…

2. The element being described is Sodium its symbol is Na it has an atomic mass of 22.989769. It has an atomic number of 11. This element has 11 protons, 11 protons, and about 11 neutrons. Protons have a positive charge, electrons have a negative charge, and neutron have a neutral charge. Electron shells are the outer parts of an atom containing the electrons. Valence electrons are electrons in the outermost shell. Valence electrons tell us whether an atom shares, transfers or receives electrons…
