Hydrogen is recognized as the simplest and lightest chemical element in the periodic table; even though it is identified as one of the top elements in abundance in the world (consisting of 0.9 percent of the total mass on earth)‚ it is considered to be the most abundant element in the entire universe. It is a gaseous element with the atomic symbol being H. It is usually categorized under the first group of the periodic table known as the alkali metals. It contains only one electron that revolves

of ATP‚ Adenosine Triose Phosphate. This occurs by converting glucose into pyruvate via glycolysis. Pyruvate is then transported into the mitochondrial matrix via active transport. Numerous reactions‚ catalyzed by a multi enzyme complex then occur‚ where the pyruvate is decarboxylated as shown in the reaction below. Pyruvate + NAD* + CoA ? acetyl CoA + reduced NAD + Carbon Dioxide This experiment shall be carried out via the manometric technique‚ where there are two different environments with

Le Chatelier’s Principle Part I: Record your observations. NaOH was dissolved in MgCl2‚ the color turned dark pink (from white) Questions In Part I the reaction you observed was Mg(OH)2 (s) Mg2+ (aq) + 2 OH- (aq). Compare the colors you observed in the experiment and answer these questions: A. Which way should the equilibrium shift when HCl is added? How do your results support your answer? It should shift to the left because adding any component causes the equilibrium to

hypothesis proposed that if a small amount of salt was added to the reaction‚ then it cause the rate of the reaction to speed up‚ but if too much salt was added‚ then it will instead decrease the rate of the reaction. The data revealed that no additional amount of salt was the reaction that had the highest rate. As shown previously in the data table‚ the first trial’s average reaction rate of 4.5 mL/min was higher than the other two reaction rates where salt was added for trial 2 and trial3‚ 2.125 mL/min and

The halides in unknown solution were identified as iodide and chloride based on their experimental E°(Ag/AgX) values‚ -0.16 ±0.01V and 0.22 ±0.02V respectively. These results were both accurate with percent error of 5.96% for iodine and 0.9% for chloride. The literature value of E°(Ag/AgI) and E°(Ag/AgCl) were -0.151V and 0.222V respectively (1). In addition‚ the literature vales lay within the 95% confidence interval for both halides therefore the results were accurate. These results were precise

The Effect of the Concentration of Sulphuric Acid on the Reaction Rate with Magnesium Sarah Cain SCH 4UB Mr. Lankin April 1‚ 2009 Introduction The nature of the problem is to design an investigation that examines a variable affecting the reaction rate. In this experiment‚ magnesium will be reacted with different concentrations of sulphuric acid. The reaction is shown by the following chemical equation: H2SO4 (l) + Mg (s) → MgSO4 (aq) + H2

experiment is to find out the rate of reaction between Hydrochloric acid (HCL) and Magnesium (Mg) in different temperatures. The products that will be formed are Magnesium Chloride (MgCl2) and Hydrogen (H2). Prediction: I predict that as the temperature increases the rate of reaction also increases. To further explore the fact I further predict that the rate of reaction will double for every 10° C rise in temperature. I further predict as the temperature rises by 10° C the rate of collisions will also

Clock reactions If you choose a project that explores the kinetics of a chemical reaction you will need a way of measuring the rate of the reaction. Clock reactions provide an interesting way of doing this for some systems. In a typical reaction the first part of a graph showing the concentration of product against time is approximately a straight line (see Figure 1). If you choose any value of concentration that lies on this straight line (say c1) the initial rate of reaction can be found
