Oxygen toxicity

Hydrogen Cyanide Hydrogen Cyanide (HCN) is an extremely poisonous liquid discovered in 1782 by Carl Scheele, a Swedish chemist. HCN is very toxic because it stops cells from using oxygen properly thus causing death. Although HCN is a great solvent for salts, it cannot be used due to its high toxicity. Even though it is general stable, it has the capacity to combust in the company of basic substances such as ammonia or sodium cyanide. What is its structure? The structure of Hydrogen cyanide is…

they become considered as a whole single ion. Moreover, it is known to have a charge, most polyatomic ions have a negative charge but there is an exception with a positive charge. In this case, nitrate consists of one nitrogen atom along with three oxygen atoms which bond in order to become a single ion. Nitrate is an ion that also has a negative charge. Furthermore, the molecular mass of nitrate is 62.0049 grams per mole. Some…

abundance of phytoplankton and macrophyte production (Ferree and Shannon 2001).The purpose of this study was to examine nitrogen and phosphorus levels at Ada Hayden Lake in the comparative context of their effect on phytoplankton abundance as well as toxicity. Based on previous labs, we have found Ada Hayden Lake to be mesotrophic-eutrophic; this supported our prediction. According to Table 2 in the appendices, the amount of D.O. decreased resulting in a lot of change. Our chlorophyll a content…

oxide of tin is the most important raw material in tin chemistry. This colorless, diamagnetic solid is amphoteric. 1.2 Structure It crystallises with the rutile structure, wherein the tin atoms are six coordinate and the oxygen atoms three coordinate. SnO2 is usually regarded as an oxygen-deficient n-type semiconductor.[4] Hydrous forms of SnO2 have been described in the past as stannic acids, although such materials appear to be hydrated particles…

Introduction: DNP and research question The organic compound 2,4-dinitrophenol (DNP) is a crystalline solid with the molecular formula C6H4N2O5. The molecule is soluble in water to some extent and is fully soluble in sodium and potassium hydroxide solutions. The compound can also be explosive. It is usually used in dye, weed killers, wood preserver, photographic development among other things and it has even been used as a weight loss agent. In fact, it has been claimed to be the king of the…

The power of the human mind is limitless and cannot be measured in any shape or form. It has the power to create and innovate unimaginable structures and formulas. It has the power to learn and adapt from failure and to think outside the box. On the other hand, nature has the capability of being either: calm and beautiful or destructive and vicious. Nature is the most destructive force the humanity has ever seen, even more, powerful than an atomic bomb. So what happens when these two forces…

alloys used in industry are of the upmost importance when it comes to longevity and reliability of structures. Many chemical compounds have been developed over the years that can inhibit the corrosion rate of metal alloys but cost effectiveness, toxicity, processibility and other factors limit the applications1. The need for new, eco-friendly and cost effective corrosion inhibitors have led to research in the field of polymer chemistry. Discussion The performance of a polymeric corrosion…

T0>T1>T11>T10>T9>T8>T7>T6>T5>T4>T3>T2. As the ETP sludge’s concentration increases the plant growth also increases in the same trend because the available N,P and K is increases gradually when the concentration of ETP sludge increases after incubation presented in figure 1. Moreover, vegetation of the treated soil proved that the presence of sludge marginally promotes the plants growth, while hindering the uptake of Zn and Pb by the leaves and the roots [25].…

the test of time and be able to become the newest coming trend in the transportation sector. With all of the technological advances, environmentally, healthily and economically electric cars do benefit the entire population and also help reduce the toxicity that the planet is now having to deal with because of all the pollution man-kind has created. Ecological Factors The use of an electric car allows to reduce the amount of toxins that are released into the atmosphere compared to all the…

gaining any CO2 at 40 minutes resulting in 1.7 mL of CO2. In the second experiment my hypothesis stated the rate of photosynthesis is dependent on the wavelength (color) of light absorbed. The rate of photosynthesis can be measured by the amount of oxygen produced from various wavelengths of light in the color spectrum. The graph generated using various wave lengths in the visible light spectrum supports the hypothesis by demonstrating the variation between wavelength and the change in the…
