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

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

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

One evening earlier this year, I needed to print a few pages for an assignment, but my computer printer was malfunctioning in my dorm room. I couldn 't believe this was happening to me. I just had a long stressful day and now this. My roommate noticed that I was frustrated and was fussing with the printer. He asked me what’s wrong and I explained the situation. He suggested that I went upstairs to use the printers on the 9th floor computer lab in South Quad. I have never been up there before so I

The case study, Is this a case of discrimination or non-performance, the author discuss the issue between Dr. George Annan, newly hired the assistant professor and Dr. Mary Reed, the department head for the Applied technology and management at Northern Plain University. Dr. Mary Reed was offered a position as the department head in August 2003. She accepted the new position and was excited to run the department. Within two years, she had a great experience working as a head of the department; however

Meth has become a normal piece of news in Muncie, Indiana. When someone searches “Muncie, Indiana problems” the first hit is “Meth Crisis.” When people think about starting a family or even just relocating to another city or town, they search the statistics and news of the various cities. If the first thing they find out about one city is that it is number one for its large per capita number of meth labs in Indiana, that’s not going to persuade anyone to move there. Without new residents and current
