Study Guide Acids and Bases: 1. Be able to identify both the Brønsted–Lowry acid and base from a given reaction. ~An acid is a proton donor ~A base is a proton acceptor H3PO4 + H20 H3O+ +H2PO4- H3PO4 is an acid so it is a proton donor. It gives its positive atom to the other element 2. Be able to calculate the pH of a solution given [H3O+] Example: What is the pH of a solution with a [H3O+] of 1 x 10-2 M? The pH level should equal the exponent number of 2. Redox Reactions: Be

Jenéshia Washington-Hughes 7 September 2011 Ms. Santi A Rose for Emily Analysis Piecing Together the Puzzle: Flashbacks and Foreshadowing in A Rose for Emily William Faulkner incorporates flashbacks and foreshadowing into the plot of “A Rose for Emily‚” to create an aura of suspense. Faulkner presents the life of the main character‚ Emily Grierson‚ in a seemingly disorganized manner‚ as the author wrote the events out of chronological order. The format of his story confuses the reader‚

Module 16 Notes Reduction/Oxidation Reactions • Oxidation number: The charge that an atom in a molecule would develop if the most electronegative atoms in the molecule took the shared electrons from the less electronegative atoms. • Oxidation numbers are not real; they are only based on assumptions. They are useful bookkeeping tools though‚ and can help us keep track of electrons during a reaction. • The sum of all oxidation numbers in a molecule must equal the charge of that molecule. • Rules

5BY2 – Fully Automated Parking “Puzzle System” 5BY2 is a company located in Amsterdam that has developed a very unique parking system‚ described as a “puzzle system”. The system requires an average of 15 m2 per car‚ a 60% improvement over a conventional parking layout[1]. By designing the layout of each level or floor of the parking system to resemble a sliding puzzle‚ where one “tile” shifts around at a time to make room for a new car or to retrieve a target parked car‚ this parking system is highly

between the molecules in a chemical reaction provides the kinetic energy needed to break the necessary bonds so that new bonds can be formed. Thus‚ increasing the concentration of the anode‚ zinc sulfate‚ will increases the rate of reaction for oxidation because there are more zinc ions in the new concentration‚ which would also increase the collision between molecules. This will eventually allow an increase in the transferring rate of electrons to the cathode‚ as there are certainly
