salicylates, and lack of oxygen from shock, heart failure or severe anemia, or seizures. Other causes of metabolic acidosis include kidney diseases such as distal renal tubular acidosis and proximal renal tubular acidosis, poisoning of aspirin, ethylene glycol found in antifreeze or methanol, or severe dehydration. The following signs and symptoms are as followed. Signs and symptoms include rapid breathing, confusion or lethargy, shock, nausea, vomiting, and fatigue. As acidosis worsens, other…

danger” he relates an incident where scientists noticed acacias on the African savannah began secreting toxic substances in their leaves as an attempt to ward off hungry giraffes. Additionally, he claims they “gave off a warning gas (specifically, ethylene) that signaled to neighbouring trees of the same species that a crisis was at hand” (Wohlleben). While I am not entirely convinced that trees do, in fact, have feelings, Wohlleben’s use of rhetoric, specifically logos, was enough to convince…

Hydraulic Fracking is a controversial issue because so little is known about it. But Fracking is some people’s way of life so we can’t just take away their jobs because they have families to feed and to take care of. But on the other hand Destroying are environment and endangering the public isn’t right either just because we need natural gas. Everyone has a side and an opinion but before making your decision on what side you’re on you should always read about it and look up facts. Fracking…

Historical Background Situated on the side of Mount Parnassus in central Greece, Delphi was a religious, panhellenic sanctuary known as the belly-button of the ancient world. This location was discovered, according to myth, when Zeus sent two eagles to fly from separate directions towards each other. They met at Delphi, then determined to be the navel of the earth. The site of Delphi was inhabited by Iron Age cults, and material evidence of 9th century bronze figurines has been recovered.…

Oil (or petroleum) is a very important thing to us. We use it every day. We use a lot of it in just a single day. Our life depends on oil. It may not be the only thing but it is one of the most important. My report is on oil and how it affects us. Oil is a fossil fuel. It was created millions of years ago from the remains of prehistoric organisms at the bottom of lakes or oceans.10,9,17 Fossil fuels are formed from the remains of dead plants or animals.The plants or animals were called plankton…

Part C Question 1 Addition polymerization In addition polymerization, polymer is formed by addition monomer without eliminating any product at specified temperature, pressure and presence of catalyst. Different methods of addition polymerization are free radical polymerization, cationic polymerization, anionic polymerization and coordination polymerization. Mainly addition polymerization occurs in the monomers having double bound. This process has three stages initiation, propagation,…

A. Defining Reaction Mechanisms and Catalyst Structure The methane-to-methanol reactions that we aimed to evaluate consist of four critical steps starting from the initial reactants (CH4, NH4+, oxo): C-H activation followed by a hydrogen atom abstraction (HAA) from CH4 to form some combination of the hydrogenated complex, ammonium or ammonia, and a methyl radical; a radical rebound (RR) to form a methanol adduct and ammonium; methanol dissociation from the metal; and catalysis regeneration via…

Ethyl vinyl ether was used to protect –OH on glycidol based on a literature reported protocal.59 In a typical procedure, 0.675 mol glycidol and 200 mL ethyl vinyl ether were loaded in a round-bottom flask, to which 1.25 g TsOH was then added. The reaction was allowed to proceed at room temperature (RT) for 3h. The resulting mixture was then purified by washing with 100 ml saturated aqueous solution of NaHCO3 for 3 times. The organic layer obtained was dried by MgSO4. After filtration of MgSO4,…
