Kenneth John S. Cretencio July 30‚ 2012 BS-CoE Reaction Paper: The Pirates of Silicon Valley The film was narrated by Steve Wozniak‚ co-developer of the Apple computer. The movie took off with Steve Jobs talking in a melodramatic way to the audience‚ it seems but as the angle of the scene shifts‚ it was shown that he was actually talking to a director and that they were currently in the middle of shooting a commercial which is for the Apple Computer. The scene then changes showing

1. Introduction: This investigation will show the effect of temperature on the rate of reaction. The Berocca tablet was reacted with hot water (47oC) and then with cold water (20oC). In the hypothesis‚ it was predicted that the temperature will be inverse proportional to the time Berocca tablet reacts with water to produce 50ml of carbon dioxide gas. Through the result table‚ we can see that the hypothesis is supported and it was correct. In the conclusion‚ it was shown that the temperature has the

Stoichiometry of a Precipitation Reaction March 20‚2013 Amber McCollum Introduction Stoichiometry is a branch of chemistry that deals with the quantitative relationships that exist among the reactants and products in chemical reactions To predict the amount of product produced in a precipitation reaction using stoichiometry‚ accurately measure the reactants and products of the reaction‚ determine the actual yield vs. the theoretical yield and to calculate the percent yield. The equation

The Displacement Reactions Purpose: to see how displacement reaction works with different chemicals and what chemical has more reactivity series then other Hypothesis: Iron + Copper Sulfate: Iron will displace copper because it is more reactive and it is going to end up as Iron Sulphide + Copper Copper + Silver Nitrate: Copper will displace Silver because it is more reactive and it is going to end up as Copper Nitride + Magnesium + Copper oxide: Magnesium will displace Copper because it

Discussion The reaction through which 4-mrthaoxyacetophenone is converted to 4-methoxybenzoic acid is a haloform reaction. This reaction involves two distinct stages that occur in the same environment. The first stage occurs through the based-catalyzed halogenation of the ketone that forms a trihalo ketone. First‚ the bleach is transformed into chlorine and hydroxide ions through the following reaction: Then‚ the hydroxyl is able to attack the rather acidic (pKa ~ 20) α-hydrogen of the ketone

≪Propose a reaction mechanism using the criteria presented in the lesson‚ with the third step as the rate-determining step. Hypothetical reaction: A + 2B + 4C ---> 2D + E The rate law has been determined to be [B]^1[C]^2≫ I had prepared the material below before I received your criteria. As you know‚ each step in a reaction mechanism is an elementary step. Each step is characterized by its molecularity. A step could be unimolecular‚ as in A → B or A → B + C It could be bimolecular as in 2A → B +

My Reaction to Apollo 13 The movie Apollo13 is great but little kind of boring. Tom Hanks is a great artist! He is my idol. One of his great movie is Forrest Gump. By the way‚ The Apollo13 is America’s third moon landing mission. En route‚ an onboard explosion deprives their spacecraft of most of its oxygen supply and electric power‚ forcing NASA’s flight controllers to abort the Moon landing‚ and turning the mission into a struggle to get the three men home safely. I thought Jim’s wife was his

Chemistry 12: Reaction Kinetics Review 1. Looking at the expressions for reaction rate‚ write expressions with which you could express rates for the following reactions. (Hint: look at what happens to reactants and products.) Recall that solid or liquids can lose or gain mass‚ gases can lose or gain volume and aqueous solutions can increase or decrease in concentration. ("a" is done as an example.) a) Mg(s) + 2HCl(aq) H2(g) + MgCl2(aq) reaction rate = mass of Mg consumed unit time b) c) or
