Sulfate

Physicians prescribed this drug in order to determine if patient Afib’s shortness of breath was due to his atrial fibrillation and not due to underlying asthma that had not been noted before. Proair HFA is one of the many trade names for albuterol sulfate. This manufacturer, along with others, now uses HFA (hyrdofluoroalkane) instead of CFC’s as a propellant in their meter dose inhalers since there were concerns about CFC’s contributing to ozone depletion (Swisher, n.d.). Albuterol works by…

When people think of a mechanic, they usually think of a person working on a car. Well, a diesel mechanic is not just a mechanic but one that works specifically on diesel engines. There is a huge difference between the two. Because of the difference, diesel mechanics are required to work on these engines in alternative ways to keep them going. Diesel mechanics have wide varied job descriptions, along with working on this unique type of engine. Diesel mechanics work on anything from transfer…

Power of Pollution Everybody knows that there are many different types of pollution, but what people don’t know is how it’s affecting their environment, and themselves. Researchers tend to focus on the types of pollution: air, environmental, sound, light and many more, but not on who and how it affects them. Not only does pollution affect animals and the environment, but it affects humans too. While limitations are put on how much pollution companies are allowed to emit out into the atmosphere,…

pharmaceuticals. The Arctic haze (airborne toxic contaminants such as herbicides and pesticides such as lindane and DDT heavy metals, such as lead, mercury and vanadium and industrial organic compounds such as DIOXINS and PCBs, and high concentration of sulfates) which are sourced from paper mills, pulps, oil and gas activities to industrial processes, smelting and combustion of fossil fuels. Pollutants in the haze can be traced to vehicles, shipping and agriculture; all used/needed for the…

Destin Briggs Lu Jack Chem 4235 11/4/2017 Original Synthesis of Cadmium Nitrate Tetra-Hydrate Cadmium nitrate tetra-Hydrate is an inorganic compound from the family of compounds with the general formula Cd (NO3)2.XH20, where X=4, hence the molecule has four molecules of water of crystallization in its structure. It exists as a salt but in its anhydrous state, it is known to be a volatile substance. It is a colorless substance as are all the compounds in the family of cadmium nitrates. Cadmium…

Biodiesel is considered to be a renewable clean burning diesel replacement that is reducing the United States dependence on imported diesel. This alternative fuel is creating jobs and improving the environment also. (www.biofuels,org, 2015) Biodiesel is made from a diverse mix of feed stocks, including recycled oil, soybean oil and animal fats. It is the first and only EPA designated advanced biofuel in on a commercial scale production across the country. Biodiesel had to pass strict…

Deep vein thrombosis (DVT) is a condition where a blood clot forms in a deep vein, usually in the legs. The deep veins pass through the deep tissues of the legs. These veins transport blood from the legs and feet back to the heart. The superficial veins are located beneath the surface of the skin, and the deep veins run between muscles of the legs. Contractions of these muscles helps to squeeze the blood towards the heart when we move our legs. Deep vein thrombosis and pulmonary embolism are…

This lab was a two week long lab called the Grignard Reaction lab. The purpose of this lab was to perform the Grignard reaction and to obtain the final product triphenylmethanol from a halide, phenylmagnesium bromide and the starting material, methyl benzoate along with the Grignard reagent. Bromobenzene, magnesium turnings, and anhydrous ether were needed to form the Grignard reagent. To synthesize the reagent, react the reagent with methyl benzoate to form a tertiary alcohol. The objective of…

In this experiment, a Wittig reaction was performed in order to synthesize a mixtures of (E)- and (Z)-stilbene. Photoisomerization was then performed to isolate (E)-stilbene by transforming (Z)-stilbene into (E)-stilbene. The presence of the products throughout the experiment was monitored by 1H NMR. The final product was then characterized by 1H NMR, IR and its melting point. During synthesize of the product, the appearance of the reaction mixture changed. The main solution…
