Enzyme Lab Majesty Collins September 26, 2017 Finding the Greatest Amount of Product with a Spectrophotometer Introduction For the enzyme experiment, I hypothesized that test tube number one would have the greatest amount of product. My lab partners and I believed that number one would have the most significant amount of product because it had the highest mL amount of the potato extract. The potato extract is the enzyme of the investigation being used which is catecholase (Picture

diabetes, polycystic ovary syndrome, as well as a number of other conditions. The analysis of insulin is often restricted by strict pre-analytical recommendations. The Chemical Pathology Laboratory at Groote Schuur Hospital Laboratory receives blood samples from a number of external hospitals and laboratories for insulin analysis. Not all samples can be analysed immediately and some may not even be centrifuged before being transported under varying conditions. Whether these samples are still

Marq, Jake, and Tiara were three close friends who bonded over 90’s hip hop. The kids were smart but dressed and looked abnormal to their environment. They lived in the ghetto and were bullied often because how they dressed and how they took school serious. The boys all had a crush on the same girl, she was graduated but still young. They all dressed in clothes from the 90’s and had hair designs just like people then. Marq is the average teenager in high school. He’s in his last year of

ends his story with a message for the students who complain about wearing their goggles. This message is “the lesson to be learned from my experience is straightforward: there's simply never an adequate excuse for not wearing safety glasses in the laboratory at all times”

Purpose The ultimate purpose of this experiment is to go through the copper cycle through various steps that include dissolution, precipitation, conversion, and reduction of copper. Throughout the processes the qualitative observations were recorded to see what effect each type of acid and decanting has on copper. All of these steps were successfully completed by using different acidic solutions and zinc to take copper through the cycle from copper solid to copper nitrate to copper hydroxide, to

1. What type of macroscopic evidence for chemical change did you observe during this experiment? Give at least three different examples. (15 points) The main evidence of chemical change in this lab is the change in color, production of gas, and the production of precipitate. These reactions can be seen from just a little bit of reaction all the way up to a complete change of the entire sample tested. Some samples of those tested in this experiment which showed the chemical reaction were the baking

Quaternary ammonium compounds (QACs), also known as quats, are usually positively charged molecules with a nitrogen atom that has four other bonds (Sabapathy, 1994). Because of the positive charge on the nitrogen atom, quaternary ammonium compounds are formulated as a salt and are usually paired with a negatively charged compound or ion (Sabapathy, 1994). In terms of practical use, QACs are commonly used as a broad spectrum antimicrobial. In other words, it affects the two major types of bacteria

The perfect example of this situation is when we had to change labs for our advanced lab testing portion related to the Partner for Health program. Originally we used HDL labatory however due to some recent bad press we no longer felt this lab was a reliable option. We had to re-assure both the patients and the client that they would recieve the same quality of testing that they were use to with previous lab draws. As part of choosing a labatory, I reseached labs that offered similar advanced lab

Date Submitted: 5/24/2015 Date Performed: 5/24/2015 Lab Section: Chem-180 Course Instructor: Professor Lea Stage Addendum to Lab 1: Physical and Chemical Properties. 1. Did you observe any chemical changes in this experiment? Yes, there was a variation of noted chemical changes in this experiment. 2. What evidence did you use to decide that something was a chemical change? There was an assortment of different changes indicating that chemical changes were taking place such as

When one is working in a laboratory there are many different methods and procedures one must follow to ensure safety. There are three main concepts to ensure lab safety; these are hand washing, personal safety, and proper disposal of materials. Following these protocols would not just helps ensure the safety of me, but also the safety of the ones around me working in the laboratory. These protocols are necessary to ensure optimal experience for the professor and students in the lab.
