  • Average Decreased Oxygen Displacement Between Beaker 1
    1,331 words
    DESCRIPTIVE TITLE The Effect of Different Amounts of Sodium Chloride on the displacement of oxygen. INTRODUCTION The dependability of the rate of an enzyme-mediated reaction is based on two factors: the substrate concentration and the concentration and action of the enzyme that catalyzes the reaction (Vander, et. al., 2001). Enzymes are catalysts that produce chemical reactions in cells. Enzymes which are large proteins perform a reaction which acts upon a substance known as a substrate. When co...
  • 1 Dropper Of Mineral Oil
    1,345 words
    Darryl Fagan Pd. 4 01-20-00 AP Chemistry An Activity Series Chemistry Lab 5 Introduction; In this experiment you will study some metals and some nonmetals to find their relative reactivity. A ranking according to reactivity is called an activity series. For example, an activity series containing the elements calcium, gold and iron would put the reactive calcium at the top, iron in the middle, and the un reactive gold at the bottom. If a piece of iron metal is placed in a solution of gold nitrate...
  • Enthalpy Change For Deltah 2
    772 words
    Evaluating An Enthalpy Change That Cannot Be Measured Directly. Dr. Watson. Introduction. We were told that sodium hydrogen carbonate decomposes on heating to give sodium carbonate, water and carbon dioxide as shown in the equation below: - 2 NaHCO 3 (s) Na 2 CO 3 (s) + H 2 O (l) + CO 2 (g) = DeltaH 1 This was given as deltaH 1 and we had to calculate as part of the experiment. This however cannot be measured directly, but can be found using the enthalpy changes from two other reactions. These b...
  • Reaction Of Sodium And Hydrochloric Acid
    1,274 words
    Introduction Over the next few weeks I will be doing several attempts of the same experiment that involves the reaction of sodium and hydrochloric acid, I will be closely watching the reaction and how long in takes for the reactants to react. As yet I have not decided which of the several variables I will be changing. I also aim to take results of the reaction down onto a table, which then will be transferred onto a line graph, which will show us the nature of the reaction. Variables There are f...
  • Reaction Of The Isolated Diamine Salt 1
    2,460 words
    Asymmetric Epoxidation of Dihydronaphthalene with a Synthesized Jacobsen " catalyst Professor Abstract. 1, 2 was reacted with L- (+) -tartaric acid to yield (R, R) -1, 2- mono- (+) -tartrate salt. The tartrate salt was then reacted with potassium carbonate and 3, 5-di-term- to yield (R, R) -N, N'-Bis (3, 5-di-term-) -1, 2-cyclohexane diamine, which was then reacted with Mn (OAc) 2 4 H 2 O and Li Cl to form Jacobsen's catalyst. The synthesized Jacobsen's catalyst was used to catalyze the ep oxida...

  • 1 4 Of The Alka Seltzer Tablet
    1,764 words
    Purpose: Try to have a chemical reaction between Alka seltzer and water be controlled so that the lid of the canister pops of in exactly 15 sec. Hypothesis: If a 1/4 of a solid Alka-Seltzer tablet and 15 mL of hot water is added then the lid of the film canister will pop off in exactly 15 seconds. Introduction: vs. Temperature- causes atoms to move faster vs. Surface area- more space to react in vs. Concentration- an amount of substance used to react with another substance. vs. Catalyst- a subst...
  • Heat Of Reaction And Heat Of Formation
    1,033 words
    Lab report Heat of Reaction Introduction: The purpose of the lab was to through experiments calculate the heat of reaction and heat of formation, and see if we got a realistic result according to facts. We should see if Reaction 1 and 2 equalled 3 We created 3 reactions and then calculated their enthalpies. Work plan Substances: Material: Material: NaOH (s) 3 Beakers, 300 ml NaCl (aq) 0.50 M Thermometer HCl (aq) 0.25 M Balance Deionised water Work plan Since the lab was pretty time consuming we ...
