Naming Chemical Compounds General Information: Scientists all around the globe use a standard method for naming chemical compounds. The standards were set up by an international committee sponsored by the International Union of Pure and Applied Chemistry (IUPAC). Having this standard makes life easier for people who use these compounds everyday. It would be tough to set up any experiment if scientists everywhere used different names for the same compound. It would also make the lab a

Introduction: Acid rain has proven to be a big problem for Connecticut. It has had a great impact on builders‚ wildlife‚ and the water sources. Acid rain has many components in it such as pollutants from plants to sulfuric acid from burning coal. Problem: Which stone is the most resistant against acid rain? Hypothesis: If we test the different stones against acid rain then red sand stone would be the best because it is heavier and cannot be easily broken. Independent variable: Type of stones

The Branch Davidian Compound was established as living-worship center for the members of the sect to reside. The residents of the compound lived‚ worked‚ learned‚ and worshipped in the isolated community. Because of the nature of the isolation and basis of the belief system of the Branch Davidian church created a unique way of life for the residents. Life in the compound was mostly dictated by David Koresh because he was a self-proclaimed messiah (equip.org) in which the members followed. Because

Lately‚ the transgender community’s push for more gender-neutral public bathrooms has drawn a fair amount of attention‚ support‚ and criticism. I identify as pansexual and I personally do not have any gender preferences. I’ve been supporting LGBT since I had an understanding of the term. There was a time I cut my hair very short and dressed more masculine than feminine. I used to get weird looks when I went to female bathrooms in public places like grocery stores and malls; therefore I had the experience

Nomenclature for Ionic Compounds Ionic compounds consist of cations (positive ions) and anions (negative ions). The nomenclature‚ or naming‚ of ionic compounds is based on the names of the component ions. Here are the principal naming conventions for ionic compounds‚ along with examples to show how they are used: Roman NumeralsA Roman numeral in parentheses‚ followed by the name of the element‚ is used for elements that can form more than one positive ion. This is usually seen with metals. You

AMINO ACIDS BY MEANS OF TITRATION CURVE ABSTRACT The aim of the experiment was to identify an unknown amino acid through acid-base titrations which was prepared in water to form an acidic solution. Each group prepared unknown amino acid hydrochloride. The pre-prepared basic solution was slowly added to the amino acid solution and pH change was closely observed using the pH meter. During these titrations the amino acid converted from cation to zwitterion to anion; zwitterion is an amino acid with
