Phelps‚ Biology 205 MW 2:10pm. Unknown Organism Paper The unknown organism tested in the Mesa lab was collected from in between the toes of my puppy‚ Riley. The original culture grown consisted of dozens of visibly different organisms of varying colony colors and growth patterns. I chose to test a smaller‚ red colony for my experiments. Based on its gram reaction and oxygen requirements‚ the following tests were performed to reach my presumptive ID: Test Performed Result Gram Stain +

Unable to read the Gram Stain at first it was later confirmed that Unknown #7 was a gram negative bacteria. When introduced to Starch Unknown #7 produced no zone of clearing showing that it did not contain the enzyme amylase. When introduced to the Lipid Unknown #7 did produce a zone of clearing indicating that it did contain the enzyme lipase. When introduced to Casein Unknown #7 produced no zone of clearing indicating that it did not contain the enzyme protease. When streaked onto the Gelatin‚

Experiment H: Identification of an Unknown Organic Compound The objective of this lab was straightforward. We were given an unknown compound and we were to perform an IR spectroscopy and as well as NMR spectroscopy. With the IR spectroscopy‚ I was able to name the functional groups I have on my compound and further confirmed my assumptions by looking at the NMR spectroscopy after. The unknown number I was given was number 203. The molecular weight of the compound was 121. From the molecular weight

However‚ the original manufacturer‚ Kaufmann Ltd.‚ has gone out of business‚ and specifications for the part are unavailable. The purpose of this experiment‚ performed by Ryan Nelson‚ Peter Glascor‚ Eric Flowr was to determine the identity of the unknown polymer by comparing its properties to properties of other known polymers. Most likely‚ the part is one of the five following polymers: polyethylene‚ polypropylene‚ polystyrene‚ polycarbonate‚ poly(vinyl chloride). These are all extremely common

For the unknown light source‚ it had almost every color‚ so it might have been be mercury because they have similar color beams and their color from the naked eye appeared as purple‚ which mercury‚ a light blue‚ is very close to in terms of it’s color on the spectrum. For the unknown flame crystals‚ it may NH4+ because the colors that appeared are very similar to the crystals. Next‚ chemicals have to be heated in the flame for the color to emit because heat adds energy to the substance making the
