EMISSIONS FROM ADIPIC ACID AND NITRIC ACID PRODUCTION A C K N O WL E D G E M E N T S This paper was written by Heike Mainhardt (ICF Incorporated) and reviewed by Dina Kruger (USEPA). ABSTRACT Nitrous oxide (N2O) is generated as a by-product during the production of adipic acid and nitric acid. The main use for adipic acid is as a component of nylon-6/6; thus production trends are closely correlated with nylon consumption trends. Worldwide‚ there are very few adipic acid plants. The U.S. is

increase the reaction rate. This will result in the particles colliding more frequently and increasing the speed of the reaction. Also when they have more energy there will be more chance of the collisions being successful because the activation energy will be attainable. Hypothesis: In a reaction between calcium carbonate and hydrochloric acid‚ the products calcium chloride‚ carbon dioxide and water are formed. I predict that the higher temperature of HCl acid‚ the higher the reaction rate will be

An investigation in to the rate of reaction Plan: I am going to investigate the rate of reaction. The reaction I will be using is: Calcium Carbonate + Hydrochloric acid ---- Calcium Chloride + water + carbon dioxide. CaCO3 + 2HCl ---- CaCl +H2O + CO2 Measurements and Variables: The variables I have chosen to change is strength of the hydrochloric acid which will be 1 mole‚ 0.7 mole‚ 0.5 mole‚ 0.3 mole and 0.1 mole some variable I will not be using are temperature‚ mass‚ density. The measurements

(Fe3+ ) form. Ferric form is not usually absorbed in the body. In the stomach‚ there is low pH of 2 due to presence of gastric acids such as Hydrochloric and Ascorbic acids. These acids provide an acidic environment for reduction of ferric iron to ferrous (Fe2+). Ferrous iron can be absorbed in the body system. As in following equation of iron (iii) reaction with Ascorbic acid ‚ the product is iron (ii) chloride which is soluble 2 Fe3+ (s) + C6 H8 O6 (aq) → 2 Fe2+ (aq) + C6 H6 O6 (aq) + 2 H (aq)+

Chemistry Research Paper What is an anti acid? According to Cindy Quarters (2010)‚ “Antacids are medicines that are taken orally to help relieve sour stomach‚ heartburn‚ or acid indigestion”. This medicine is available without prescription but it is needed to take the correct dose. The different types of anti acids include calcium carbonate‚ sodium bicarbonate‚ magnesium hydroxide‚ aluminum hydroxide‚ and dihydroxyaluminum sodium carbonate. The cost of the anti acid will depend on how effective it is‚

The purpose of this investigation was to determine which type of alcohol (ethanol‚ butan-1-ol‚ or propan-2-ol) contains the most energy per gram. It was expected that if we burn three alcohols (ethanol‚ propan-2-ol‚ and butan-1-ol) for 2 minutes‚ then butan-1-ol will release the most energy per gram (J/g) because butan-1-ol contains more carbon atoms than other alcohols which means more energy is required to break its chemical bonds and more energy will be released when new chemical bonds are formed

Separation of Amino Acids by Paper Chromatography Chromatography is a common technique for separating chemical substances. The prefix “chroma‚” which suggests “color‚” comes from the fact that some of the earliest applications of chromatography were to separate components of the green pigment‚ chlorophyll. You may have already used this method to separate the colored components in ink. In this experiment you will use chromatography to separate and identify amino acids‚ the building blocks of proteins
