Abstract This lab report focuses on the two experiments on pressure systems conducted, the Marcet boiler and Boyle’s law. The aim of this lab is to investigate in pressure-temperature relationship, Boyle’s law, as well as steam quality. The results of this experiment support both relationship, as well as successfully providing a value for steam quality. For the Marcet boiler experiment, it was found that the higher the system pressure, the higher the saturated temperature. For the Boyle’s law…

Name: ______________________________________ Date _________________ Lab Partner _________________________________ Section _______________ Objectives: To determine freezing points of pure solvent and solutions using cooling curves. Calculate the freezing point depression for the solutions of unknown. Calculate Molar Mass of unknown solute. Introduction: When a solute is dissolved in a solvent, the freezing temperature is lowered in proportion to the number of moles of solute added. This…

with the stress of senior year at hand, it is easy to be pessimistic with school work and college applications and scholarships. I try to be a positive light in the lives of my friends, because I have learned how to handle the stress of school. A single word can change someone’s perspective of their adversities. Handling each situation as an egg and a carrot lead me to making mature decisions and growing as a person. I believe that this is what it means to handle adversity as a coffee bean.…

The kinetics of the reaction between peroxomonosulphate with Lactic acid was studied in the presence of Mn(II) at alkaline pH. The reaction followed first order with respect to peroxomonosulphate. The rate of the reaction was studied under pseudo first order condition and found to increases with the [Mn(II)] and lactic acid. Thermodynamic parameters were calculated and reported. Based on the results a rate equation, kinetic scheme and a most probable mechanism has been predicted. Keywords: Alpha…

acid from Oxalate. For this 9.004 grams of Oxalate is required and dissolved in 1000ml of water. Molecular weight of Oxalic acid = 90.04g [C=12.01; H=1.01; O=16] 1mole = 90.04g so, 0.1mole = 9.004g Oxalic acid in 1000ml of distilled water. Reaction for Oxalic acid and Sodium hydroxide: C_2 H_4 O_4+2NaOH →〖Na〗_2 CO_4+2H_2 O (The ratio between Oxalic acid and Sodium Hydroxide is in the ratio 1:2) For carrying out titration take 25ml NaOH in a conical flask using a pipette and fill up the…

surface blocking the active surface sites in the LDH. The maximum photodegradation efficiency was obtained at the dye concentration of 1 x 10-5 M. 3.11.4. Recyclability of 2:1 Co/Ti LDH After each degradation cycle, the LDH was separated from the reaction system, was regenerated by washing it three times with de-ionized water followed by drying,…

This report gives an information which is related to the reaction between acidified potassium iodide and hydrogen peroxide. Before calculating the rate of this reaction, the reaction will be carried out 3 times and values will be got. A special timer will be used to measure the time. It could be expected and argued that each time will be able differ from the others in each reaction and it can be explained by changing the quantity of hydrogen peroxide. At the final, it will be obviously observed…

decreases after a threshold value of 1.266. This has been shown by the CFD analysis. 3. Conclusions There is single chimney flow pattern in case natural convection heat transfer which reduces heat transfer from surface. So making notch is effective method for increasing heat transfer. The values of heat transfer coefficient are higher for notched fin arrays giving better performance. The single chimney flow pattern is also present in…

15SPE072X 27012016 EXPERIMENT 7: Cannizzaro reaction and reaction of benzaldehyde with ethylene glycol Introduction: From the first experiment, the reaction of benzaldehyde and potassium hydroxide will produce two products which are benzyl alcohol and benzoic acid. We are going to look at how to get this two products separated by using their different chemical properties. For the second experiment, benzaldehyde ethylene acetal is formed when the reaction done under acidic environment.…

3.7. Equilibrium isotherms Langmuir isotherm proposed by Langmuir, (1918) with some limitations Dąbrowski, (2001) expressed as: (4) Where qm (mg g–1) is the maximum amount of the metal ion per unit weight of adsorbent, ‘qe’ is equilibrium adsorption capacity (mg g–1), ‘Ce’ is the equilibrium concentration of the adsorbate (mg L–1), and b is a constant which reveals the affinity of binding sites (L mg-1). From the plots between (Ce/qe ) and Ce the slope (1/qm ) and the intercept…
