dealing with such small quantities of reagents‚ any small inaccuracy in measurement creates a large difference in actual yield from theoretical yield. Through simple molar calculations‚ using the coefficients in the balanced chemical equation( CaCl2(aq) + 2NaOH(aq) Ca(OH)2 + CaCl2)‚ the limiting reagent could be determined from the volumes of reactants used. The number two to four tests turned out as expected‚ NaOH and CaCl2 respectively being the limiting reagents. In the second test‚ according to

Frank Lucas: The American Gangster INTRO There is no question that when you hear about the true “American Gangster” someone is talking about Frank Lucas. Before being arrested and sentenced to jail‚ Frank claimed to be making $1 million a day selling drugs on 116th Street in Harlem‚ NY. He was known for buying his supply directly from Southeast Asia‚ also called the “Golden Triangle”. It was said that he would smuggle the drugs using the coffins of American service men. Frank Lucas was a heroin

Question 1 (Limiting Reagent) 15.00 g aluminum sulfide & 10.00 g water react until the limiting reagent is used up. [Atomic mass: H = 1.008‚ Al = 26.98‚ S = 32.07‚ O = 16.00] Here is the balanced equation for the reaction: Al2S3 + 6 H2O ( 2 Al (OH)3 + 3 H2S (i) Which of the two reactants is the limiting reagent? (ii) What is the maximum mass of H2S which can be formed from these reagents? (iii) How much excess reagent remains after the reaction is complete

Fra Luca Bartolomeo de Pacioli (sometimes Paciolo) (1445–1514 or 1517) was an Italian mathematician and Franciscan friar‚ collaborator with Leonardo da Vinci‚ and seminal contributor to the field now known as accounting. He was also called Luca di Borgo after his birthplace‚ Borgo Santo Sepolcro‚ Tuscany. Luca Pacioli studied in Venice and Rome and became a Franciscan friar in the 1470s. He was a travelling mathematics tutor until 1497‚ when he accepted an invitation from Lodovico Sforza ("Il Moro")

George Lucas Slide 1: No other 20th century filmmaker has had a greater impact on the film industry than George Lucas. His zeal for innovation forged a new relationship between entertainment and technology that revolutionized the art of motion pictures. His uncanny business acumen turned film licensing and merchandising into a multibillion-dollar industry. And his "Star Wars" trilogy ushered in the era of the Hollywood mega-blockbuster. Slide 2: In 1967‚ Lucas re-enrolled as a USC graduate student

Determining the Stoichiometry of Chemical Reactions Objective In this lab we took Fe(NO3)3 and NaOH and mixed 7 different mole ratios in graduated cylinders to determine what the mole ratio is. We also did the same thing with solutions of CuCl2 and Na3PO4. We determine the mole ratios by graphing the volume of reactant #1 vs. volume of precipitate for each reaction. Data Part 1.)

| Reactions of Grignard Reagents with Carbonyls | | | Tuesday 1:30 | 2/28/2012 | | Introduction This experiment explores the reactivity pattern for the addition of Grignard reagents to three different carbonyl groups: a ketone‚ an ester‚ and a carbonate. Grignard reagents are organometallic compounds that have a carbon-metal bond‚ such as carbon-magnesium. Grignard reagents are formed from the reaction of an alkyl‚ cycloalkyl‚ or aryl halide and magnesium metal in dry ether
