Introduction The goal of this experiment was to determine atomic weight of Kandimonium and the relative number of M&M’s in Kandimonium. Kandimonim is composed of three isotopes: Skittles, M&M’s, and Sweet Tarts, and the ratio of Sweet Tarts to Skittles is 27:18. The relative number of M&M’s and the atomic mass were determined by weighing each of the different Isotopes and calculating their average masses for further calculations.…
In this Beanium lab, the objective was to make sense of the numbers used to calculate average atomic mass. By separating, counting, and weighing beans we were able to create the numbers used to calculate the weight of one bean. From there, we could use the total number of beans to produce the percent abundance for each type of bean. These were the numbers that we had to produce in order to understand how and why there are many types of isotopes for each element. In doing this lab, we can think through the importance of finding the average atomic mass and not just using a single isotope for an element.…
Process To Make Copper Coated / Plated Nails 1) Measure out 1/4 cup white vinegar and put into the glass bowl. 2) Add 1 teaspoon salt. Stir salt until it dissolves in the vinegar. 3) Take a penny and submerge it into the vinegar solution 1/2 way for 10 seconds.…
ISOTOPE EXPERIMENT- BEANIUM Introduction This beanium experiment was performed to display a greater understanding of isotopes of an element. Atoms that belong to the same element with the same number of protons but differ in numbers of neutrons are called isotopes.…
Abstract: The Grignard reaction was successfully accomplished. An amount of 1.20 ml of 2-methyl-2-pentanol was collected, and 9.60% yield was calculated based on the theoretical yield. Despite the low amount of 2-methyl-2-pentanol, its identity was confirmed by comparing the experimental refractive index and infrared spectrum to the literature refractive index and infrared spectrum of 2-methyl-2-pentanol. Statement and purpose The purpose of this experiment is to synthesize a specific alcohol by using the Grignard reaction.…
Magnesium Chloride as a Deicer Emily Lekah Fall 2015 CHEM 1066 October 15, 2015 University of Minnesota Abstract The purpose of this experiment was to evaluate magnesium chloride as a deicer. To be a good deicer, a salt must be able to lower the enthalpy when is mixed with water. This will cause an exothermic reaction and release heat.…
To find the moles of Magnesium, dimensional was used to multiply the molar mass of Magnesium to its measured mass, the final result is 5.3475936 x 10-3 moles. 0.13g Mg×(1mol/(24.31g))=5.3475936×〖10〗^(-3) After adding Hydrochloric acid and been heated on the hot plate, the total mass of evaporating dish plus Magnesium Chloride is 44.96 grams. By subtracting the mass of Magnesium ribbon 0.13 grams from the total mass 44.96 grams, the mass of Magnesium Chloride was found to be 0.56 grams. 44.96-44.40=0.56g After knowing the mas of Magnesium chloride, by subtracting the mass of Magnesium ribbon from it, the mass of Chloride was found to be 0.43…
There may have been errors in the lab that may have affected the results of the lab. There may have been mistakes: a person may have not measured the substances correctly while retrieving the liquids in the graduated cylinder, or not have been watching the conductivity probe while the group was measuring the electrolyte solution. Along with these, there is also the issue of timing the testing incorrectly. Adding onto this, there may have been a slight spill where the accurate amount of the substance being used was not completely added into the water for testing.…
1. The reported mole ratio of magnesium to oxygen will be too high. The experiment will have less oxidation while burning. Since there are 2 oxygen and some of the magnesium evaporates as it burns, the ratio will be higher than usual 2.…
In this experiment, solid magnesium was conducted in a chemical reaction with hydrochloric acid solution. The three objectives include: measuring the gas production of a chemical reaction by a pressure change, determining the mass of the hydrogen gas produced in the reaction, and determining the effectiveness of the procedure by calculating the percent yield. In order to complete these objectives, a flask containing the magnesium ribbon was completely submerged into a large beaker filled with water. Next, hydrochloric acid was emptied into the flask using a gas syringe. Then, a Gas Pressure Sensor was used to measure the pressure in the sealed vessel, and a temperature probe was used to measure the temperature of the reaction indirectly by…
In today’s day and age it is very easy to access foods with magnesium. For example, you can simply walk into Metro and buy green vegetables, whole grain cereals, nuts and beans, and seafood. We have the privilege to go to a pharmacy and simply buy supplement to help us improve our intake of magnesium. Some additional food items that maintain magnesium are mackerel, boiled spinach, bran breakfast cereal and almonds. Foods with the highest magnesium per milligram are cocoa, bran breakfast cereal, almonds, cashews and pumpkin seeds.…
Investigation Hooke’s Law AIM: To investigate how a spring behaves when a force of load stretches it. To figure out the relationship between the loads added to spring and the extension of spring. HYPOTHESIS: I think that as the load added to spring increases, the extension of the spring will increase. The relationship between them will be directly proportional. The formula of these two variables might be F=kx.…
Conclusion: The the precipitation reactions lab eight out of the fourteen occurring reactions were precipitates. A precipitate means that a solid substance was formed or a substance that is not aqueous was formed. The reactions that did not form a precipitate were DNR, which means that they did not react. At station one barium chloride and potassium nitrate did not react but barium chloride and silver nitrate reacted to form barium nitrate and silver chloride. The precipitate at station one was silver chloride.…
The equilibrium will shift to the right and [HI] will decrease. 4. 20 grams of magnesium were placed in a conical flask. Which one of the following solutions, if added, would produce 100 mL of hydrogen gas the fastest? A. 100 mL of 4 M sulfuric acid B. 200 mL of 2 M sulfuric acid C. 400 mL of 1 M sulfuric acid D. 50 mL of 8 M sulfuric acid 5.…
Aluminum alloys are lighter than magnesium metal alloys. If the two metals are both cast into similar geometric shapes such as square bar, round bar, or tube as it is the case in the problem here, the easier way to differentiate the two metals is by measuring their density. Since aluminum and magnesium alloys are both silvery and have very close melting points (660 and 650 degrees Celsius), the only substantial difference is in their densities (Robson et al, 2012 p 450). Aluminum has a density of 2.7g/ml whereas Magnesium has a density of 1.7g/ml.…
