Experimental: Materials – double salt (self-made & EIU Chemistry Stockroom), 6 M HCl (EIU Chemistry Stockroom), 10% BaCl2, 6 M HNO3 (EIU Chemistry Stockroom) Equipment – Ocean Optics Spectrometer USB4000, Logger Pro Procedure – In order to find the mass percent of the sulfate, the sulfate needed to separate itself from the rest of the double salt. To do this, experimenters began by weighing out 0.998 g of the double salt into a 250-mL beaker. They then used the graduated cylinder to add about…

In exercise 1, experiment A, the students will need a microscope slide, a coverslip, a compound microscope, carmine powder, distilled water, and a pipette. The students will begin by placing a drop of water on the microscope slide. Then they will add carmine powder onto the slide. Then they will place a coverslip on top of the solution. This will aid in mixing the solution. Then the students will observe the movement of the carmine particles on low power and high power. In exercise 1,…

The procedure for Lab 5 contained four parts. For Part A, a clean, dry 100 mL beaker was obtained and filled with 60 mL of distilled water. Next, the beaker was placed on a ring stand with a thermometer attached to the ring stand to record the temperature of the water. After the thermometer had been in the water for two minutes, the temperature was recorded. Following the recording of the temperature, a 10 mL pipet and a bulb was used to pipet 10.00 mL of distilled water into a clean, dry,…

During the extraction process, the sand bath was set to 20℃. The 1.00 gram of ground nutmeg was transferred to the round-bottom flask (RBF) using the plastic funnel. Three milliliter of tert-butyl methyl ether and two or three boiling chips were added into the flask. The black plastic connector was used just like the distillation column with air condenser set-up. The flask was clamped to the ring stand using 3-pronged clamp. The flask was lowered into a slightly depression in the sand without…

important: What equipment it is likely to relate to (examples): Knowledge of equipment Knowledge of the equipment in which is in the laboratory is very important, as the equipment in which needs any maintenance is then kept maintained. It is also important so you know the places in which equipment needs to go in and you know where to look for specific things. - Where the glassware is situated as it should all be grouped together to decrease chances of breakages or equipment becoming damaged.…

and returned to Ron with the same results. Before going forward with the findings due to their implications, Ron decides he needs an independent investigator for the findings. For that reason, Ron reaches out to another predoctoral student is his laboratory to repeat the experiment without notifying Gordon. The predoctoral student is ordered not to discuss…

There is a required category of classes for me to graduate from UCI called Arts and Humanities. It means I have to choose at least two classes that I do not have lots of interests among religions studies, histories of art and music. That is why I enrolled in Music 8, a class mainly talks about the histories of the Beatles. The introduction of this class was pretty much fun or at least funner than east asian languages and literatures. I like the Beatles, and I thought I could have a easy time…
