    CARBOXYLIC ACID Introduction: Organic compounds containing (–C(O)–OH) as a functional group are called carboxylic acids. The –C (O)-OH group which itself is made up of a carbonyl group (>C=O) and a hydroxyl group (-OH) is called a carboxyl group (carb from carbonyl and oxyl from hydroxyl group). Carboxylic acid may be an aliphatic or an aromatic depending upon whether –C–OH is attached to an alkyl group ( or a hydrogen atom) or an aryl group. Their general formulas are; ALIPHATIC CARBOXYLIC ACID: R–C

    Acid rain is considered precipitation in the form of rain‚ snow‚ or fog. It is not regular precipitation. It is precipitation that is polluted by acid. Emissions of sulfur dioxide and nitrogen oxide into the atmosphere cause this precipitation to become acidic. These emissions are released into the atmosphere by human activity‚ such as automobiles‚ industries‚ and electrical power plants that burn fossil fuels like coal and oil. When these gases are released‚ they mix with water vapor in the clouds

    Acid Property #1: The word acid comes from the Latin word acere‚ which means "sour." All acids taste sour. Well known from ancient times were vinegar‚ sour milk and lemon juice. Aspirin (scientific name: acetylsalicylic acid) tastes sour if you don’t swallow it fast enough. Other languages derive their word for acid from the meaning of sour. So‚ in France‚ we have acide. In Germany‚ we have säure from saure and in Russia‚ kislota from kisly. Base Property #1: The word "base" has a more complex

    Jennifer Everett Phase 4 DB Instructor: Clement Yedjou 3/10/2015 Acid rain Acid rain is a result of air pollution that is harmful to the environment‚ generally caused by fuels being burnt. When any type of fuel is burnt‚ many different chemicals are produced. These gases that are released react with the water in clouds‚ and the rain from these clouds is acid rain. This type of acid disposition can appear in many other forms besides just rain‚ such as sleet‚ snow‚ and fog (Editorial Board‚ 2013)

    Acid Rain and the Effects of our Monuments and Churches The two controlled experiments that I chose to do‚ do not involve trees or plants‚ which I think a lot of people will be doing. I wanted to explore the devastation that acid rain does to our historic monuments and beautiful churches. My first controlled experiment is based on the Statue of Liberty. It is made of copper so I am using pennies in my experiment. (nps.gov. n.d.) My observation is that acid rain corrodes metals

    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
