Simulation Lab Report

In the scientific method lab, I explored the different food options for mice in order to find the best one that will help them gain weight. To succeed in this lab, I needed to examine several types of foods including fruits, raw meat, cooked and uncooked foods. In this experiment I used cooked macaroni as a positive control and for the negative control I didn’t feed the mice any food, only water. The main objective of this study was to determine the best solution that will help me understand the metabolism of mice. All mice used in this study were given the same resources, but the only difference was the different types of foods fed to the mice to understand the changes of weight gain or loss between the mice.

-Bubbles of gas began to produce itself around the aluminum which had appeared to let off vapor

gas bubbles serves as evidence that the catalase enzyme is working. As catalase is breaking the

The moment an Alka-Seltzer tablet hits water, it begins to fizz. These tablets are over-the-counter antacids and pain relief medications that contain aspirin, sodium bicarbonate, and citric acid. The fizzing is a result of a reaction occurring where carbon dioxide (in the form of bubbles), water, and sodium acetate is formed. The fizzing and carbon dioxide bubbles are a result of the sodium bicarbonate splitting and reacting with the citric acid. In this experiment we are determining the percent by mass of sodium bicarbonate (NaHCO3) in Alka-Seltzer tablets and exploring the relationship between amounts of reactants and products.

This is a stimulation review of a cardiac care unit that is facing working capital shortages. As the lead financial consultant brought into address the financial indicators and evaluate to bring working capital back to in order at the Elijah Heart Center (EHC). The other financial analyst will focused around addressing issues as they relate to this particular cardiac care unit; what funding can be acquired to garner medical equipment; what funds can be used for capital expansion; finally a summation of findings and a conclusion of what the overall stimulation showed, in regards to how through the analyst were.

On average the Alka Seltzer tablet dissolved faster in hot water in comparison to ice cold water and room temperature water. The beaker with ice cold water caused the Alka Seltzer tablet to dissolve the slowest. The three beakers containing different temperatures of water, all produced carbon dioxide bubbles; however, the beaker containing hot water produced the bubbles more rapidly.

AP Chemistry Mrs. Johnson Chemistry Butane and Inquiry Lab Submitted By Germaine Washington September 30, 2016 Abstract The purpose of these experiments was to determine the validity of the Ideal Gas Law. In the first experiment we used a Butane lighter to conduct a collection of C4H10 gas over water, with which we would measure the volume of the butane produced. It was found the 0.16 g of Butane gas at 299°K and 1.005 atm held a volume of 100mL. The results supported the Ideal Gas Law, PV = nRT.

The reason why I chose that you would encourage more minority form firms to apply for these contracts is because any article of the city of Richmond versus Crow sign 1989 it really does state that it's illegal for the cities and states to give preference to minority owned firms but, with the amount of the racial discrimination that's going on you don't want to violate the equal protection Clause of the Fourteenth Amendment that way minorities get something better than nothing. To impose on the curfew law was because, of minors do not have the same Constitution protection as in the notebook with minors they are underage

When four paper clips were added to the cup, the water had not even begun to show signs of spilling. By the end of the experiment, the cup of water was able to hold 120 paperclips before the water ran over. As the 119th paperclip was added, we noticed a somewhat large “half bubble” on the surface of the cup. This ‘bubble’ was caused by 3 factors known

To maximize net worth over the course of module 6, I focused on completing orders as fast and efficiently as possible. Using a combination of timing, effectively ordering materials and prioritizing orders, I maximized production and turnover. During the simulation, I found bidding on contracts that allowed the longest time frames for completion with the highest payouts was the most effective strategy. I was able to bid on contracts I knew I would secure and order materials during the same turn. I was able to be even further ahead and I had a lot more leniency while manufacturing each order.

From the results that were acquired from mixing the liquid reagents with each powder, it was determined that Unknown Mixture #1 consisted of baking soda and cornstarch. When individually testing the substances from Unknown Mixture #1 with the liquid reagents, a few noticeable reactions occurred. Mixing baking soda with vinegar caused bubbling to occur. This is because a neutralization reaction took place between the two reactants. In this reaction, sodium bicarbonate(baking soda) reacts with vinegar and produces sodium acetate, water, and carbon dioxide(HC2H3O2(aq) + NaHCO3(aq) NaC2H3O2(aq) + H2O(l) + CO2(g) ). The gaseous carbon dioxide most likely tried to escape into the atmosphere and caused the bubbling to occur. Another noticeable reaction

In conclusion, the more baking that was added in the reaction the more gas that was produced. When there was only one scoop of baking soda, the least amount of gas was produced, when three scoops of baking soda were used, the most amount of gas was produced. The number of bubbles roughly stayed the same, so the number of bubbles created was not affected by the amount of baking soda. With increments of 1 scoop of baking soda, small amounts of gas are produced each trial. We compared each trial by identifying the firmness of the bag due to the gas. Since gas takes up space of the bag, the more firm the bag is, the more gas is produced. Therefore, our hypothesis of having more baking soda will make more gas is correct.

For this lab, we brought a empty soda can to school to show how pressure and temperature can affect the structure of the can. To begin the experiment, we needed a empty soda can, water and ice in a small plastic tub, and a hot plate. First, we added about a tablespoon of water to the empty soda can. Second, we put the soda can on the hot plate and waited until the water was brought to a boil. Then we used beaker tongs to carry the hot soda can and flipped it over into the container of water and ice. Once the can touched the water, the can made a loud crushing sound and the can crippled inward.

The soda ash form experiment 3 was obtained. A 250 ml beaker was obtained and rinsed.

Record the height of the bubbles in a table every minute until the stopwatch reaches 5 minutes.
