Chemical Proportionality (Carbonate and Hydrochloric Acid) Introduction: The purpose of this experiment is what happens when a solid substance‚ a metal carbonate is added slowly to a solution of an acid. We are finding methods of determining acid concentration. For us to balance certain equations‚ we will use a stoichiometry. For this experiment‚ we will need to set up the ratio and finding the concentration of HCI. Procedure: • Grab 4 different beakers. • Add a small amount of sodium carbonate

The progressive aphasia severity scale (PASS) is a clinical instrument used to rate presence and severity of impairment in specific domains of speech and language in patients with PPA (Mesulam et al.‚ 2009; Sapolsky‚ Domoto-Reilly‚ & Dickerson‚ 2014). The clinician uses his or her best clinical judgment to make ratings on a 5-point scale: normal (0) to questionable/very mild (0.5)‚ mild (1.0)‚ moderate (2.0)‚ or severe (3.0) impairment. First‚ a baseline profile is established; then‚ follow-up

Experiment 18 Chemistry 101 Redox Titration: Determination of the Percentage of Iron in a Sample INTRODUCTION The concentrations of redox-active species can be determined by redox titrations. In a redox titration‚ a measured sample of the unknown is titrated against a standard solution of a substance that will oxidize or reduce the unknown. In the present experiment you will take a sample containing iron‚ add acid to dissolve it [thereby converting all the iron to iron(II)]‚ then

REACTIONS OF HYDROCARBONS Vanessa P. Manibpel De La Salle University - Dasmariñas ABSTRACT Five substances namely Hexane‚ Eugenol‚ Unknown hydrocarbon 1‚ Unknown hydrocarbon 2‚ and Acetylene gas was used for the selective reactivity of hydrocarbons to functional group tests; Bayer’s test‚ Bromine test light‚ Bromine test dark‚ and Tollen’s test. In Bayer’s test‚ only Acetylene‚ Eugenol and Unknown hydrocarbon 2 reacted positively and the rest retain the purplish color of KMnO4. On the other hand

My Reaction Paper This is my reaction paper on a movie that I watched entitled “The Wizards Of Waverly Place: The Movie”. Wizards of Waverly Place: The Movie follows the Russo family as they embark on a vacation to the Caribbean resort where Jerry and Theresa first met. Alex‚ upset that she was forced to accompany her family on the trip‚ conjures a spell that erases her parents’ fateful first meeting and puts the Russo family’s very existence in peril. In order to reverse the spell‚ Alex

On Kohlberg’s scale‚ I consider myself to be on the conventional level‚ Level II. I can say that I still react to my family’s expectations. Not so much of my peers‚ because I’ve learned that everyone have their personal opinions to everything. Sometimes‚ even unsolicited advices are given‚ I don’t intend to be rude to them in any way‚ therefore‚ I take it as creative criticism. These things happen all the time. I do conform to the norms that I learned at home and in school‚ not so much from

Large Scale Universe to Milky Way SCI/151 07/07/12 Cosmology‚ as defined by Encarta Dictionary is “the philosophical study of the nature of the universe.” This concern with viewing the universe and its vast issues and meaning takes the mind into a mysterious spectrum. The very foundation of Cosmology began with Astronomer Edwin Hubble in 1929. He discovered that other galaxies existed in the universe and determined that these galaxies were moving away from each other at a rate that was constant

Introduction Chemical Kinetics‚ described as the study of rate of chemical processes‚ varies on many factors to determine the time needed for a reaction to complete. The rate of reaction of a chemical reaction is important‚ as reactions are of little use if the time period needed for the reaction to occur is too lengthy. Many factors influence the rate of a chemical reaction‚ such as temperature‚ concentration and surface area. The order of the reaction is based on the concentration of the reactants
