Analysis of a Carbonate-Bicarbonate Mixture Manalo‚ Ma. Cristina Joyce B. Department of Chemical Engineering‚ Faculty of Engineering University of Santo Tomas Espana‚ Manila A. Abstract Crude sodium bicarbonate or commonly known as soda ash may contain amounts of impurities like chlorides and hydroxides. The total acid neutralizing capacity of a soda ash sample‚ its alkalinity value‚ was stated in terms of mass of sodium carbonate. In doing so‚ any sodium hydrogen carbonate present in the

Pig Trachealis Smooth Muscle Pharmomechanical coupling uses Internal Calcium stores whilst Electromechanical coupling uses Extracellular Calcium Crystal Nguyen School of Anatomy‚ Physiology and Human Biology‚ The University of Western Australia‚ WA‚ 6009 Introduction Smooth muscle contraction occurs when calcium is present in the smooth muscle cell and binds onto calmodulin to activate myosin light chain kinase (Wilson et al.‚ 2002). Phosphorylation of myosin light chains result in myosin

ABSTRACT The objective of this project is to optimize the preparation of modified Calcium Oxide (CaO) to capture CO2 by carbonation through hydration of ethanol/water. The carbonation reaction is the basis for CO2 capture systems. However CaO as regenerable CO2 sorbents in industrial processes is limited by the rapid decay of the carbonation conversion with the number of cycle carbonation/ calcination. Therefore Calcium based sorbents have attracted renewed attention as possible sorbents for cyclic

Preparation and Ferroelectric Characterization of Calcium doped Barium Titanate ceramics ABSTRACT Barium Titanate (BT) is widely used in electro-optical and electroceramic industry because of its ferroelectric‚ thermoelectric and piezoelectric properties when it assumes the tetragonal structure. In addition to its Lead free composition‚ its perovskite structure allows variation of ionic size and small displacement of atoms that lead to the distortion of the structure which has a profound

Purpose Since there are two possible oxidation numbers for the iron nails‚ by this experiment we will need to determine the actual oxidation number of the iron in this experiment. Hypothesis As said in the introduction there will be two possible decomposition reactions: Fe (Ⅱ) + CuCl2 (aq) → Cu + FeCl2 2Fe (Ш) + 3CuCl2 (aq) → 3Cu + 2FeCl2 We can measure the mass of the two iron nails‚ and the copper after the reaction. Thus‚ we can compare the ratio of the mole and the mass of iron and copper. Procedure

Decomposition of Sodium Chlorate to Create Oxygen Gas Introduction: There are several types of chemical reactions. Those reactions include synthesis‚ decomposition‚ single replacement‚ and double replacement. In this experiment‚ we will be decomposing sodium chlorate to create oxygen gas. In a decomposition reaction‚ a chemical compound is being separated into elements or simpler compounds. AB → A + B is a simple way of expressing what happens in a decomposition reaction‚ AB break down into A

Anatomy and Physiology Assignment Research project: The role of calcium and vitamin D in the development and maintenance of bone structure What is Parathyrin? Parathyrin is a substance made by the parathyroid gland that helps the body store and use calcium. A higher than normal amount of parathyrin causes high levels of calcium in the blood and may be a sign of disease. Parathyrin is also sometimes known as Parathormone‚ parathyroid hormone and PTH. What is Calcatonin? Calcatonin is a hormone

P LANNING Aim: Our aim is to detect which factors affect the rate of the decomposition of hydrogen peroxide with a fixed mass of catalyst. A catalyst is a substance‚ which alters the speed‚ or rate of a chemical reaction but is chemically unchanged at the end of the reaction. The two factors that we can change are the temperature and the concentration. We chose to vary the concentration of hydrogen peroxide. The catalyst to speed up the reaction without affecting the result will be manganese
