hydrolyze the product. The proton is bonded to the oxygen to making the final product neutral and a tertiary alcohol. Experimental In the beginning of the lab, a clean 100 mL round bottom flask, 1.002 g of Mg turnings, 4.5 mL of bromobenzene, heating mantle, stir bar, stir plate, water hoses, condenser, and grease were obtained. The bottom of the condenser was greased and connected to the flask. The heating pad was placed under the flask and the stir plate was placed under the heating pad. The…

often found meeting points of what are called tectonic plates.350 million,or one in 20 people in the world live within danger range of an active volcano.Volcanoes aren’t only found on the boundaries of tectonic plates though,they can also occur over mantle plumes super hot areas of rock inside the…

In 1912, German meteorologist Alfred Wegener proposed the theory that all the continents were once all one continent and then later drifted apart and separated leading to the seven continents we have today. He thought that 200 million years ago there was one large continent that he called Pangea, which means “All-Earth.” During the Jurassic period the continents were believed to break up into two smaller continents which were called Gondwanaland and Laurasia. The continents were breaking into…

most of the global "magma ocean" had crystallized, with less-dense rocks floating upward and eventually forming the lunar crust. Now impacts of other asteroids and stuff have hit the moon and created the craters. Structure Earth’s moon has a core, mantle and crust. The solid, iron-rich inner core is 149 miles in radius. It is surrounded by a liquid iron shell 56 miles thick. The crust has a thickness of about 43 miles on the moon's near-side hemisphere and 93 miles on the far-side. It is made…

“I have nothing with this answer, Hamlet. These words are not mine,” for which the king would speak to his son in Act 3, Scene 2 of William Shakespeare’s longest written piece, Hamlet (Hamlet from Folger Digital Texts). As it would appear, among many a reputable scholar these words ring true pertaining to its author. The majority of those well-versed in Shakespearean history theorize that Shakespeare was not the true author of the literary works in his name. Evidence corroborating the claim…

1960’s J. Tuzo Wilson proposed hot spots and transform boundaries at a time when we had a little bit more information and knew something was going on but it was still radical to think there could be stationary hotspots. Holms hypothesis was that the mantle would generate heat that would produce convection currents that moved the land. He had to overcome to popular belief in the scientific community that Earth was immovable. His work with the geologic time scale and his talent with radioactive…

metaphorically describing the behavior of teenagers’ years after this was written. Persephone’s readiness to grow up is evident from the beginning of the poem. As the narrator says, “She sees the same person, the horrible mantle/of daughterliness still clinging to her.” The mantle of daughterliness is just a symbol of her being young. She hates being young so bad that she goes as far as to call it horrible and say it is clinging to her. The connotations of these words aren’t usually positive.…

Adaptations Adaptations are features of an organism which allow it to survive in its niche, ultimately allowing it to reproduce. Adaptations can be structural, behavioural or physiological. Structural adaptations are physical features of an organism, behavioural is something the organism does and physiological adaptations are chemical processes an organism uses to survive. Each adaptation an organism has, has a purpose to help it survive in its niche. Green Chiton The Green Chiton has…

present for his victims and for its beneficiaries. However, in general, race, like all forms of oppression, puts us in a precarious position: it introduces us an illogical and unproductive competition, then we would need the opposite to reject the mantle of oppression that we all carry on our shoulders, or because we try to keep it, or because we are fighting to get rid of it all together. At this stage of humanity we are engaged in mutual destruction on military, economic, environmental and…

Dennise Hernandez Mount Tambora Planet Earth has several types of volcanoes. Some are simply asleep, others are definitely extinct, and many volcanoes have some activity going on, waiting to go into eruption every so often. Among these volcanoes, one is known for its catastrophic damage that caused climate change. Mount Tambora, a stratovolcano in Sumbawa, Indonesia, had been showing activity since 1812, when it began to rumble and generate a black cloud. In those times, unfortunately, the…
