Morgan Stanley Experiment 7: Calorie Content of Food Report submitted:3/9/2013 Title: Calorie Content of Food Purpose: To measure the energy content of various food items and to become familiar with energy units like calories and joules. Procedure: measure the energy content of a variety of foods by burning a portion of food and capturing the heat released to a known mass of water in a calorimeter and identify units of measuring heat such as calories and joules. Data: | Marshmallow | Peanut | Popcorn | Food Item Description | Small & White | Small & Salted | Extra Butter | Mass of food & holder – initial | 15.2 | 17.3 | 14.9 | Mass of food & holder – final | 13.7 | 12.5 | 11.4 | Mass of food burnt | .70g | .5g | 0g | Mass of beaker | 4.2 | 4.2 | 4.2 | Mass of beaker & water | 54.2 | 54.2 | 54.2 | Mass of water | 39.9 | 42.6 | 44.83 | Water temp. – initial | 48 | 45 | 47 | Water temp. – final | 36 | 33 | 46 | Delta T (oC change | 12C | 12C | 1 C | Questions: A.
Calculate the concentration of grams of sodium stearate per milliliter of diluted solution. To do this, multiply the concentration of sodium stearate in the dishwashing liquid by the dilution of the solution (1.50 mL dishwashing liquid per 100 mL solution). Answer = 1.5 *10^-4 g/mL 4. Calculate the number of moles of sodium stearate in a single layer. To do this, first take the number of drops used to achieve the monolayer (1 drop) and convert it to mL using the calibrated number of drops per mL.
In a small saucepan, heat ½ tsp. of olive oil, fry a small onion that should be chopped and add a tin of chopped tomatoes cook this till it starts to boil. Add mushrooms and sweet corn, mix and cook for another 2 minute 2. In a medium size oven-proof dish, put 6 lasagne sheets, cover the sheet with the sauce, then put another 6 lasagne sheets and cover with sauce, put another 6 lasagne sheets and cover with white sauce and top with grated cheese. Put the dish in the oven for 15-20mins 3.
Bring to a boil, reduce heat, and simmer one and half hours, or until tender. Drain the beans and reserve the liquid. Heat the oil in a separate pot, (skillet) a little over medium. Then, sauté shallot and garlic until odorous. Then, fry beans with shallot and garlic for about two minutes.
With your spoon move the rice in a circular motion. Keep stirring until rice is a golden color. When the rice is golden, carefully remove the pot from the stove and set aside. Get your blender; add about four whole tomatoes from the can, ¼ of an onion, and 1 cup of water. Cover the blender with a lid and blend for 1 minute.
Kyla Emerine Date of Experiment: April 15, 2015 Report Submitted: August 17, 2015 Title: Colligative Properties and Osmotic Pressure Purpose: To observing changes of colligative properties in freezing and boring points, by adding salt to a solution. Procedure: In this experiment I performed various procedures such as adding different amounts of salt to tap water that was freezing or boiling and observed how it changed the temperatures. Data Tables: Data Table 1. Dialysis Tubing Results Time: |Mass of Dialysis Tubing and Contents | 0 minutes |6.5g| 30 minutes |6.8| 60 minutes |7.2| Questions A. In your experiment, is the light corn syrup in the dialysis tubing hypertonic or hypotonic to the water?
No matter the variety, original, crinkle, or baked, they are all manufactured with oil. This test will show how much oil each of these types of chips hold. I will be preforming a test with three varieties of 7-11 Select brand chips; Original Potato Chips, BIG BITE Hot Dog Potato Chips, and Kettle Style Salt and Vinegar Potato Chips. I will weigh out 0.5oz of potato chips, crush them on graph paper, and let them set for 1 minute. I will then remove the chips, observe the oil residue left behind, and record the data.
Introduction: Thyme contains a surprising amount of iron compounds. This experiment enables us to determine the amount of iron(II) present in dried thyme by means of a redox reaction. Method: 1. Weigh accurately about 1g of dried thyme and put into a 250cm3 beaker. Record the mass of thyme used.
Now that everything is set up, one is ready to begin the process of making oreo balls. First, one’s hands should be washed thoroughly. Then take the whole package of oreo cookies and place them in a food processor. Mix the oreo cookies until they are just crumbs. Add the softened cream cheese to the food processor and make sure that the oreo cookies and cream cheese are mixed well together.
Place the 5cm strip of tape on the bottom half edge of the Petri dish. Place the 100 kernels in the bottom half of the Petri dish. Notice that the 100 popcorn kernels are to represent 100 nuclei of atoms. Put the lid on the Petri dish and shake it around, make sure not to shake fast or hard. Put the dish on the flat surface and count out the popcorn kernels that are pointing to the 5cm masking tape.
