Business Management (BM2223A) Lecturer’s name : Madam Suchitra Title : ACID RAIN Order : Topical Order General Purpose : To inform Specific purpose : Acid rain is harmful to environment that it can damage everything over a period of time because it makes the living things in the environment die. Central idea : To inform my audience about the causes‚ effects and what can be done to reduce of acid rain. Introduction I. What would you do if you knew poison was falling

Ammonia and Hydrochloric Acid Lab Chemistry 1 Abstract The straw should be cut shorter to 8 cm in order to make the solid ring appear in the center of the straw. We achieved our goal‚ cutting the straw caused the gases to not have to go as far‚ and meet in the middle. Background The particles in a gas are very loose and tend to move around a lot very quickly. The particles in a solid are very compact and vibrate but don’t really move very much. The particles in a liquid however are more

1. What is the movie all about? Lorenzo’s Oil Lorenzo is the son of Michaela and Augusto Odone. He begins to have strange memory problems and blackouts. At age 6‚ he is diagnosed with the childhood cerebral form of ALD‚ a progressive degenerative nervous system disorder. There is no cure for this disease and his parents are told he will become totally disabled and die in a few years. Michaela and Augusto‚ devastated by Lorenzo’s diagnosis‚ decide to research ALD even though neither has a

What is Acid Rain? First identified in 1872 in Sweden and studied in the U.S. beginning in the 1950s‚ acid rain is precipitation in the form of rain‚ snow‚ hail‚ dew‚ or fog that transports sulfur and nitrogen compounds from the high atmosphere to the ground. Sulfur dioxide (SO2) and nitrogen oxides (NO‚ NO2) are bi-products from burning fuels in electric utilities and from other industrial and natural sources. These chemicals react with water‚ oxygen‚ carbon dioxide‚ and sunlight in the atmosphere

Amino acids are the building blocks of proteins. Amino acids bind together to form polypeptide chains‚ and these polypeptides fold and coil together into specific conformations to form proteins. There are 20 different amino acids‚ each amino acid consisting of four distinct partners. The first is a carboxyl group. A carboxyl group has very weak acids that are able to donate hydrogen ions to biological reactions. The second partner is the amino acid group. Amino acid groups act as the base which‚

________________________ Internal Assessment Criteria Aspect 1 Aspect 2 Aspect 3 Total DCP CE Aim: The aim of this practical is to plot and investigate the pH titration curves for the titration of a strong acid with a strong base and of a weak acid with a strong base‚ and find Ka of the weak acid. Procedure: Part I 1. Pour 30 ml of the HCl solution of unknown concentration in a 100 ml beaker. 2. Add a stirring magnet. 3. Place the beaker on the magnetic heater and activate the rotating motor but not

| An acid is a chemical substance any of various typically water soluble and sour compounds that are capable of reacting with a base to for a salt‚ that redden litmus paper‚ that evolve hydrogen on reaction with various metals‚ that in water solution yield hydrogen ions‚ and that have hydrogen containing molecules or ions able to give up a proton to a base or that are substances able to accept and unshared pair of electrons from a base. An alkaline is a chemical compound that neutralizes or effervesces

Chapter 4: Nucleic Acids and the RNA World 1. 4.1 – What is a Nucleic Acid? * Nucleic acids are made up of monomers called nucleotides * Three components of a nucleotide: 1. Phosphate group—attached to the 5’ carbon 2. Sugar – carbonyl group and several hydroxyl groups 3. Nitrogenous base * The prime (‘) symbols indicate the carbon being is part of the sugar—not attached to the nitrogenous base. * Four different nucleotides‚ each of which contains a different nitrogenous

Lorenzo’s Oil and ALD Disease still not fully understood Disease Description The movie "Lorenzo’s Oil" brought a rare disorder called adrenoleukodystrophy (ALD). It is a progressive degenerative myelin disorder‚ meaning that myelin‚ the "insulation" around nerves‚ breaks down over time. Without myelin‚ nerves can’t function normally‚ or at all. Unfortunately‚ the body can’t grow replacement myelin‚ so the disorder is progressive -- it gets worse over time. Nerve Cell diagram:

Common Aspects of Acid Prehydrolysis and Steam Explosion for Pretreating Wood Hans E. Grethlein Michigan Biotechnology Institute‚ PO Box 27609‚ Lansing‚ Michigan 48909‚ USA & Alvin O. Converse Thayer School of Engineering‚ Dartmouth College‚ Hanover‚ New Hampshire 03755‚ USA Abstract The initial rate of hydrolysis using cellulase from Trichoderma reesei for various wood samples is directly proportional to the surface area available to the enzyme. Both dilute acid hydrolysis in a continuous
