In order to compare the two reactors used in our experiment, a simplified global kinetic model was used to describe the DRM reaction behavior in different plasma reactor. This model was already used by authors in the field of pollutant removal by using a plasma reactor [15, 21–23]. It is generally accepted that free radical processes are the main mechanisms in non-equilibrium plasma reaction [21, 24-25].…

After completing this experiment several of the chemicals just simply changed colors. The main colors shown were blue, yellow, pink, green, and a brownish black. A few of the reactants did not change to a different color at all, but did show little signs of bubbles at the surface.…

At the beginning of the lab, a micro test tube with and without glass wool was weighed on an analytical balance. A watch glass, crucible, and lid were also weighed. The masses of all the materials needed for the lab were recorded in the data tables of the laboratory notebook. An unknown vial was obtained from the teacher and set to zero on the balance. About 0.6 grams of the unknown was measured into the micro test tube. The analytical balance was set to zero again and then the test tube with the unknown was measured and recorded.…
Obtain and wear goggles. 2. Measure and record the mass of a clean, dry crucible without cover. Obtain about 1 g of the unknown copper chloride hydrate and place it in the crucible. Use a spatula to break up any large pieces of the substance by pressing the pieces against the wall of the crucible. Measure and record the mass of the crucible with compound. 3. Set up a ring stand, ring, and clay triangle for heating the sample. Rest the crucible on the clay triangle. Set up a lab burner and ignite the burner away from the crucible. Adjust the burner to get a small flame. 4. Hold the burner in your hand and move the flame slowly back and forth underneath the crucible to gently heat the sample. Do not overheat the compound. Note the color change, from blue-green to brownish, as the water of hydration is driven out of the crystals. When the sample has turned brown, gently heat the crucible for two more minutes. 5. Remove and turn off the burner. Cover the crucible and allow the sample to cool for about ten minutes. 6. Remove the crucible cover and inspect your sample. If you see any blue-green crystals, reheat the sample until the crystals have turned brown. 7. Measure and record the mass of the cool crucible of your copper chloride sample. 8. Transfer the brown solid to a clean and empty 50 mL beaker. Rinse out the crucible with two 8 mL aliquots of distilled water and pour the water into the 50 mL beaker. Gently swirl the beaker to completely dissolve the solid. Note that the color of the solution is green as the copper ions are rehydrated. 9. Measure out about 20 cm of aluminum wire, coil the wire, and place the wire in the beaker of solution so that it is completely immersed in the copper chloride solution. Note that the reaction produces a gas, elemental copper is forming on the surface of the aluminum wire, and the color of the solution is fading. The reaction will take about 30 minutes to complete. 10. When the reaction is done, the solution will be colorless.…

Chemical Engineering is the branch of engineering concerned with the design and operation of industrial chemical plants. I have been interested in chemical engineering at a young age because I have plenty of engineers in my family. I was influenced by my family to go into engineering because I witnessed how much my family worked, and how much it is able to support my family. Becoming an engineer ensures me of a stable job, and I will be financially stable. Chemical engineering is a job that needs a hard worker that is determined; it has a good income, and is a job that I will love.…
