Filtration using a Buchner funnel
Chemistry
Water
Acetophenetidin can be synthesized using two methods: Williamson ether synthesis and amide synthesis. Working in pairs, we were able to successfully complete both synthesis routes. The ultimate goal is to verify that the two individuals’ methods yield a similar product. Initially, the Synthesis reaction started by eliminating the colored impurities from the p-phenetidine. This was…
NaCl Affects on Enzymatic Reaction
Chemistry
Enzyme
Nature
Enzymes have a critical function in cells as they increase chemical reactions by lowering the activation energy necessary for the reaction to occur. Potatoes (Solanum tuberosum) possess highly efficient enzymes for production, but it is desirable to hinder their activity. By inhibiting the catecholase enzyme in potatoes, the occurrence of browning during cooking can be…

Zinc Oxide Crystal Structure
Chemistry
Crystal structure Zinc oxide crystallizes in three forms: hexagonal wurtzite, cubic zincblende, and the rarely observed cubic rocksalt). The wurtzite structure is most stable at ambient conditions and thus most common. The zincblende form can be stabilized by growing ZnO on substrates with cubic lattice structure. In both cases, the zinc and oxide centers are…

I will besides be demoing a chart that includes the Agent, and many other utile information about nervus gas agents which are the chief point for chemical warfare. This study will besides include the effects of nervus gas on the human organic structure….
Classification of Chemical Substances
Chemistry
Metals will SSE electrons to form actions (positively charged) and non-metals can gain electrons to form anions (negatively charged); these oppositely charged ions attract each other and form an ionic compound Because the attraction of the ions is so strong, ionic compounds are always solid at room temperature and usually crystalline with high melting and…

Not all colourss are the consequence of minus and add-on of visible radiation. Some colourss like the blue sky consequence from the selective sprinkling of the colourss of visible radiation by atoms in the ambiance. The colour scattered by the atoms depends on the size of the atoms themselves. BLUE SKYViolet is scattered more than…
The Pros and Cons of a Carbon Tax
Chemistry
Climate Change
Nature
Carbon tax is an environmental tax levied on the carbon content of fuels. It is a form of carbon pricing. Carbon is present in every hydrocarbon fuel , such as coal, petroleum, and natural gas. It is then released as carbon dioxide (CO2) when they are burnt. In contrast, non-combustion energy sources—wind,sunlight, hydropower, and nuclear—do…
