Chemically, polyester (or many esters) is primarily a family of polymers wherein the monomers belong to the category “esters”. The most commonly used polyester is the polymer of diglycol terephthalate and is called polyethylene terephthalate (PET). Nylon is a group of polymers, which can be classified as polyamides. Today several types of nylon are produced with properties tuned to meet customer specifications. The most commonly used ones are nylon-6 (which is manufactured from caprolactam) and…

Discussion There were four goals for Project 11: Identification, Properties, and Synthesis of an Unknown Ionic Compound. The first goal was to identify the unknown compound, the second goal was to determine the reactivity of the compound, the third goal was to determine the quantitative solubility of the compound in water, and the fourth goal was to find the percent yield of a product from a reaction involving the unknown compound. Determining the identity of the unknown compound was achieved…

Comparison of Organometallic Compounds of Transition Metals and Main Group Elements Organometallic Compounds: The compounds which contain at least one direct metal to carbon covalent bond are known as organometallic compounds many of these are thermodynamically unstable and are pyrophoric. The meta may belongs to main group, transition metal, f group metal or a metalloid i.e. selenium, boron, arsenic, silicon, antimony, germanium, and tellurium and the carbon moiety may be alkyl, alkene, alkyne,…

death”(Nrdc.org, 2018). Exposure of disel exhaust makes researchers worried for the health of people and what will be the outcome if fracking continues to release chemicals into the air. “Some of the pollutants released by drilling include: benzene, toluene, xylene and ethyl benzene (BTEX), particulate matter and dust, ground level ozone, or smog, nitrogen oxides, carbon monoxide, formaldehyde and metals contained in diesel fuel combustion with exposure to these pollutants known to cause…

Where: i : Number of components Xi : Mole fraction for component ( i ) Cn: The total number of carbon atoms Cni : Number of carbon atoms for component ( i ) H_m = ∑ X_i H_mi (3.3) Where: Hm: The total number of hydrogen atoms Hmi : Number of hydrogen atoms for component ( i ) CnHm : The average chemical formula So the average chemical formula has been determined as in the above equations according to the percentages…

religion for hundreds and thousands of years. Ibogaine is the tryptamine molecule that is primarily responsible for Iboga's effect. Ibogaine similar to serotonin, but with a methyl molecule where the hydroxy group would be, and a more complex toluene structure with an ethyl group coming off. Ibogaine acts on almost all receptors in the brain, but primarily the…

2.1 Nanocomposite and nanofiller Composite is the combination of two or more different materials that are mixed together in order to bring out the best properties of both material. A nanocomposite is the composite which exhibit at least one dimension of the nanoparticle size material [17]. The nanoparticle size is mainly used as the disperse particle system to enhance or improve the properties of the composite material such as strength, conductivity and wear resistance. The main reason for…

It has been proven to disrupt the thyroid hormone that controls brain development in mice. Solvents, such as toluene, may cause reduced learning ability, speech and motor skill issues in children. Children born to women who sniffed glue during pregnancy were found to be affected with these concerns. The effect of other solvents on the human developing brain have…

I am originally from a small rural community in Ohio which has poor regulation on the air and water quality which humans depend on to sustain life. Throughout the city, hydraulic fracking has become a common method to obtain energy. This method of obtaining energy is misconceptualized to be a cleaner alternative to oil and coal, however, with a first hand on experience with living in this area allows me to witness otherwise. This city is known as Youngstown, Ohio. Hydraulic fracking is a…
