of mixture Metal C 25.605g 24.6mL 25.2°C 100.5°C 28.7°C Calculations: Show your work and write a short explanation with each calculation. Part I: 1. Calculate the energy change (q) of the surroundings (water). We can assume that the specific heat capacity of water is 4.18 J/ (g · °C), and the density of water is 1.00 g/mL. (4 points) q = m × c × Δt Given: q=?

Focus Question Should chemists prepare Zinc Iodide, from its elements or from a Double Replacement Reaction between Barium Iodide and Zinc Sulfate? -To put things into perspective in terms of cost efficiency, zinc granules cost about $62.50 per kilogram or $.0625 per gram. Also, Iodine chips cost about $.1498, Barium Iodide Dihydrate costs about $.886 per gram, and Zinc Sulfate Heptahydrate costs about $.0405 per gram. According the chemical reaction listed below, the double replacement reaction creates a solid Barium Sulfate precipitate This means that the ZnI2 is less pure than it would be from just the Zinc and the Iodine. With the elemental reaction you get ZnI2 as your only product thus indicated that it is “pure” Zinc Iodide.
What is the volume of both tanks if the radius of the tank #1 is 15 feet and the height if tank #2 is 120 feet. You must explain your answer using words, and you must show your work to receive credit. - Since the formula for cylinders volume is V=π r² h, you would just plug in the feet and the height. V=3.14*9^2*72 1) 3.14 * 15² *120 2) 3.14 * 225* 120 3) 706.5 * 120 4) 84,780 ft The volume is 84,780ft for one whole tank, but the tanks are half of a cylinder, so that means that the volume would be half of what the whole would be. One tank volume would be 42,390ft.
Greg is driving a remote control car at a constant speed. He starts the timer when the car is 5 feet away. After 2 seconds the car is 30 feet away. Write a linear equation to find the distance d of the car from Greg. Estimate the distance the car has traveled after 10 seconds?
mass = _____S_______________ 3. speed = ______S______________ 4. displacement = __V___________ 5. length = ____S_______________ Objective Four: Make and interpret position-time graphs that are equivalent representations that diagram an object’s uniform motion. Directions: Answer the following questions in the space provided. 1.) The graph to the right shows the distance versus time for two cars traveling on a straight highway. a.
In part one of the lab we used a micro scale technique to derive an activity series for metals. With the use of this technique we measured the same amount of different metal nitrate solutions into each well. Then we placed a piece of metal in the other metal nitrate solutions. With the data we recorded we resulted our activity series for the metals. We resulted that lead, silver, and copper are the strongest oxidizing agents, and that magnesium and zinc are the weak oxidizing agents.
