Sulfur trioxide

Leo Fauvel & Michael Bruce AS91387 VITAMIN-C CONCENTRATION Purpose The purpose of this investigation was to study the effects of vitamin C decreasing in concentration over time after being exposed to oxygen. This occurs by the ascorbic acid (which is the organic molecule known as vitamin C) breaking down in the process of oxygen in an oxidation reaction. Enzymes in the citrus fruits increase the rate of oxidation. A deaeration step minimizes amount of oxygen so the amount of ascorbic

Who’s Blood Races down a Shirt the Fastest? “The black, submissive sky recedes when the influence from the white, imperious moon disrupts the balance of candid humanity,” my brother always said. “There are too many big words, Damien. I don’t get it,” I would respond. “One day you will, Uriah. One day.” He loved talking with the bartender who lived down the street. Damien made sure to visit Mr. Caver after the full moon each month. What do you think of black skin? Is it dirty? Is it clean? Before

From the precise moment that man first polluted the world, from burning fossil fuels to urbanization; a chain reaction was created that brought along significant problems for future generations. Many people were unaware of the threatening long-term effects that came along with these massive innovations. One of the many serious threats is acid rain and the majority of people did not notice the effects of this worldwide dilemma. It is now apparent that acid rain has made a significant negative impact

Mining; the act, process or industry of extracting minerals from the Earth. This is a relatively simple term that most people, especially in Minnesota, are familiar with due to Northern Minnesota’s iron range, which is home to the MinnTac facility, the largest iron ore operation in the Unites States. However, the proposed PolyMet sulfide mining project would be the first of it’s kind in the state's history. In order to protect and conserve the environment along lake Superior in Minnesota, and keep

Aim To investigate the effect of temperature, concentration of reactant and particle size on the rate of reaction Introduction Rate of reaction is the amount of reactant used up per unit time. Reaction occur only when the molecule of the reactant collides with a proper orientation along with the energy equal to or greater than the activation energy. Some of the factors that will affect the rate of reaction are: A: Temperature • The rate of reaction increases as the temperature increases • The particles

CARBON SOURCE The lignocellulosic hydrolysate will be prepared by the National Institute of Molecular Biology and Biotechnology (BIOTECH, UPLB) from sweet sorghum bagasse subjected to pretreatment followed by sulfuric acid (0.75 wt% and pH 1.1) hydrolysis at 100∘C. BACTERIAL STRAIN Cupriavidus necator is a bacterial strain that is commonly used in accumulating poly-3-hydroxybutyrate (PHB), the most common type of PHA. It is most effective when the amount of carbon source present is in excess

Extremophiles – R. pachyptila By Richard Wilmer Extremophiles are organisms that are adapted to not only withstand but thrive in extreme conditions. R. pachyptila or “giant tube worm” is a barophile found on the Pacific Ocean floor able to withstand extremely high pressures. It can grow up to 2.4 metres and inhabits environments with a temperature range of 2 to 30 degrees Celsius. It is one of many organisms that reside near hydrothermal vents, specifically black smokers that produce high levels

Imagine drifting slowly on a canoe while fishing one of Minnesota's crystal clear waters on a beautiful, sunny day. Now imagine being interrupted by the loud, ongoing sounds of drilling and being told the fish were too dangerous to eat. This is only one of many potential harms of sulfide mining. PolyMet, a new mining company would like to bring sulfide mining, also known as copper-nickel mining to Minnesota. This would involve the extraction of copper and various other metals from sulfide, hence

Introduction: Magnesium sulfate, MgSO4, also commonly known as Epsom salts, is generally present in mineral water. It is used as a bath salt to relieve muscle aches and stiffness and as a laxative. Magnesium sulfate is a hydrated salt and will lose its water if it is not in the presence of oxygen and also through high temperatures. Magnesium ions are essential for plant growth, as they form part of the chlorophyll molecule used to convert sunlight into chemical energy. A solution of magnesium sulfate

New Method in Ultrahard Material Synthesis: CS2 Catalyzed Ultrahard Fullerite Ultrahard materials is a broad category define by materials that are harder than diamond. Diamond, thought to be the hardest material for centuries hasn’t been the hardest material seen by scientists in a long time. Many materials have been developed or discovered recently that surpass the 150 GPa hardness of diamond by as much as 100%. There are many ways to measure the hardness of a material, from the classic scratch
