Sulfur trioxide

The isotherms of three samples investigated by the nitrogen adsorption/desorption were shown in Figure 2. The curves of all three samples show hysteresis behavior and belong to type IV isotherms31. It suggests that our samples exhibit mesoporous structure with pore sizes larger than 5.6 nm (Table 2). The pore diameter of thiol-functionalized SBA-15 calculated by the BJH theory is smaller than that of SBA-15, which is attributed to the anchoring of thiol moiety to the silanol group in the interior

The Industrial Revolution The Industrial Revolution was a great leap in manufacturing technology that had many benefits to mankind. The standard of living was raised to a higher level, products were being made could be made more efficiently and with less production costs, and many people became able to support themselves and live a life away from their parent's farm. Because of the reduction in production costs, the prices of goods could be reduced as well. This gave the poorer masses more access

The Chemistry of Painting Cars It is necessary to paint cars because the paint protects the steel of the car from corrosion, paint fills and smooths out any imperfections in the steel surface and it provides a durable, decorative, glossy appearance. If rusting continually takes place the car becomes unsafe. When water and oxygen come in contact with the metal of the car surface, several redox reactions happen. The oxygen is reduced to hydroxide ions and iron

Background: Before January 2008, industrial accidents were the main cause of Hydrogen Sulfide poisonings in Japan. Since then, the use of this gas in chemical or “detergent” suicides increased exponentially, over 2,000 such suicides have been reported in Japan. This trend was next encountered by first responders in America, with 3 cases reported in 2008, 9 in 2009 and over 30 incidents in 2010 (Morii et al., 2010). The new trend was shared via internet message boards. Dependant of the mixture of

The Methyl Red and Voges-Proskauer broth is a combination medium that contains peptone, glucose, and a phosphate buffer that produce proteins, fermentable carbohydrates, and a consistent pH level (Leboffe, Microbiology Laboratory Theory and Application). The Methyl Red test uses the Methyl Red and Voges-Proskauer broth to determine if an organism produces stable or unstable acid by performing a mixed-acid fermentation of glucose. If an organism produces a stable acid, it is positive for executing

It is one of the basic building blocks of life and is essential in maintaining our health. Organic Sulfur Benefits - 23 Surprisingly Impressive Benefits 1. Organic Sulfur works like chelation therapy. Organic sulfur is one of the most powerful and effective solutions for detoxifying the entire body because

Introduction Magnesium sulphate is used for a variety of purposes i.e. bath salt and as a laxative. It is a hydrated salt and is required to be stored in a sealed container to maintain the water. Magnesium sulphate in a solution is sprayed on plants or poured on soil, as magnesium is vital for plant growth and respiration, it forms part of the chlorophyll molecule which is utilised by plants to convert sunlight into energy. This experiment was performed to determine the degree of hydration for a

Aeromonas hydrophila is a heterotrophic, gram negative, rod shaped bacteria surviving in both aerobic and anaerobic environment thus ferments both glucose and sucrose. These are ubiquitous bacteria meaning those appearing everywhere. These are also opportunistic organisms meaning that these attack on the organisms that are already weakened due to attack by bacteria or virus. Thus people with impaired immune system are more prone to attack by these organisms. Also young children are more easily affected

Selenium Essential to the human body, selenium is a trace element which defends against oxidation and is important for our immune response and for proper thyroid function. Located in Group 16 of the Periodic Table of Elements, selenium has the following element information: Atomic Symbol - Se Atomic Number - 34 Atomic Mass - 78.96 Discovered in 1817 by Swedish Scientists, Jacob Berzelius and JG Gahn, selenium was first thought to have been tellurium - an earlier discovered element. After further

Discussion: As figure 1 shown, ammonium sulphate have different concentrations from 0.1mol in 200ml water to 0.4mol. When concentration is increasing, the average change is from 0.26g-0.1g. Also Ammonium Dihydrogen Phosphate have the same inverse relationship that when the concentration is increasing, the weight of change decreases from 0.5-0.06g as shown in figure…. In addition, the higher the concentration, the more effective the flame retardant is. Both ammonium sulphate and ammonium dihydrogen
