Experiment 1: "A cis to trans conversion" Saturday‚ June 25‚ 2005 4:19 PM Notes on Theory • Alkenes o They are hydrocarbons with a C=C double bond • Double bonds are stronger and more reactive than single bonds o Hydrocarbons with double bonds used to be known as "olefins"‚ because they had an oily appearance • "Oleum" means oil • "Ficare" means make • Isomers o Geometric isomers have the same molecular formula‚ but a different geometric arrangement • They also have different physical properties

Experiments #7A & 7B 7A. Electrochemical Cells 7B. Formation of a Complex Ion Chem 102 Section 3095 Grace H. Kim Dec. 15‚ 2011 Abstract Two experiments were conducted to figure out the value of the formation constant of tetraamminecopper(II)‚ Kf‚ with different methods and which experimental method produces more accurate result. One was electrochemistry using a Daniel cell and the other one was spectrometry by estimating concentration of complex solution using a calibration

of hydrogen carbonate were heated in a test tube and a lit wooden splint was put in the opening of the test tube. Also in part 2 of the lab the same steps were repeated with copper sulfate. In part 3 of the lab 20 drops of HCl were added to a test tube with a small zinc piece. It was then heated with a lit wooden splint in the opening. Also in part 3 of the experiment a small piece of steel wool was added to a test tube with 10 mL of 0.6M copper sulfate. In part 4 of the lab 2 drops of 0.1M

Subject: Chemistry Topic: The Periodic Table The periodic table is a classification of all the elements based on ATOMIC NUMBER. It is composed of HORIZONTAL PERIODS and VERTICAL GROUPS which contain the elements arranged: *the order of INCREASING ATOMIC NUMBER *in the relation to the ELECTRON STRUCTURE of the atoms *in the relation to their CHEMICAL PROPERTIES (Criteria Used For Placing ELEMENTS in the Periodic Table) 1. ATOMIC NUMBER 2. NUMBER OF SHELLS (PERIOD) 3. NUMBER OF OUTER

Experiment #8 – properties of Alcohols and Phenols Introduction As has been mentioned before‚ over 20 million organic compounds have been identified. If each substance had to be studied as an entity completely separate from all the other substances‚ the study of organic chemistry as a whole would be impossible; that is to say‚ even more impossible than you currently believe it to be. Fortunately‚ the subject can be organized and it is often organized around the concept of the functional group
