  • Disadvantages Of Air Pollution

    pollution. Just as it affects our health it affects our environment. Air pollution is said to be the primary cause of global warming and acid rain. Temperatures and sea levels rise, icebergs melt and habitat is lost. After gases are released from burning fossil fuels the contaminated air combines with water droplets from the rain making it become acidic. Acid rain can cause damage to human, animals, and…

  • The Synthesis Of Aspirin

    one of the basics is aspirin, also referred to as acetylsalicylic acid. There are many different reactions that can be conducted in order to synthesize aspirin. One way being the Fischer esterification, which is a reaction between an alcohol and a carboxylic acid within the presence of a catalyst, synthesizing an ester (Weldegirma, 2014). The catalyst has to be something that will provide the addition of a proton, such as a Lewis acid, in order to provide a more reactive electrophile and speed…

  • Deodorannt Essay

    is initially odorless, it contains natural oils, called lipids that provide a growth medium for bacteria living on the skin. These bacteria interact with the lipids, converting them into compounds that have a characteristic sweaty odor. Isovaleric acid, for example, is one chemical compound that gives sweat its smell. There are two primary types of products used to control body odor. The first, deodorants, reduce body odor by killing the odor-causing bacteria. These…

  • Essay On Bio Macromolecules

    An insight in the biophysical properties of bio macromolecules Natural biopolymers such as nucleic acids, proteins and carbohydrates are essential for life as we see it today. It is incredible to think how this vast set of molecules that are in every living thing, from bacteria to human beings, are mostly made up by six elements (carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus). These biopolymers have the properties to, from small monomers, build giant tridimensional structures with a…

  • Analysis Of Sn1 Reaction

    The expression "SN1" is the abbreviation of "unimolecular nucleophilic substitution reaction", one of the most common reactions in organic chemistry. As a fundamental reaction type, the mechanism of SN1 reaction has long been clear to the researchers, and the rate of the reaction concluded from the mechanism is quite simple. According to the mechanism, the rate of an "ideal" SN1 reaction is only proportional to the concentration of the substrate, which can be expressed as the following formula:…
