Review I Constants i Perlodic Table As a food chemist for a major potato chip company, you are responsible for determining the salt content of new potato chip products for the packaging label. The potato chips are seasoned with table salt, NaCl. You weigh out a handful of the chips, boil them in water to extract the salt, and then filter the boiled chips to remove the soggy chip pieces. You then analyze the chip filtrate for Cl- concentration using the Mohr method.First you prepare a solution of silver nitrate, AGNO3, and titrate it against 0.500 g of KCl using the Mohr method. You find that it takes 64.5 mL of AgNO3 titrant to reach the equivalence point of the reaction. You then use the same silver nitrate solution to analyze the chip filtrate in a Mohr reaction, finding that the solution yields a rusty brown precipitate when 45.4 mL of titrant is added. Part A If the sample of chips used to make the filtrate weighed 76.5 g , how much NaCl is present in one serving (105 g ) of chips?…

OTHERMOCHEMISTRY Using specific heat capacity to find temperature change 84°F Sunny A chemical reaction takes place inside a flask submerged in a water bath. The water bath contains 5.20 kg of water at 33.7 °C. During the reaction 84.5 kJ of heat flows out of the flask and into the bath. Calculate the new temperature of the water bath. You can assume the specific heat capacity of water under these conditions is 4.18 J-g¹K -1 . answer to 3 significant digits.

How would you solve c?   Transcribed Image Text:Temperature (°C) AN A student conducts an experiment to determine the value of for the dissolution of Na₂C₂H₂O₂ (s). The student dissolves 10.0 g of Na₂C₂H₂O₂ (s) in room-temperature water in a beaker and measures the temperature over time. The data are given in the graph above. 24- 22- 20 18 16 14 12- 10 Time (a) The student touches the side of the beaker after the dissolution has occurred and observes that it is cold. What experimental evidence is consistent with the student's observation? (b) Is the dissolution of endothermic or exothermic? Justify your answer in terms of the flow of energy between the system and surroundings. in kJ/mol. (c) The student calculated the energy change for the dissolution to be 4600 J. Based on this value, calculate AH soln

For the arrhenius equation what are the other deviations for the formula like the ones i have to solve for t1 and k1.

Module 14 Discussion: Logarithmic Application A Radiative Forcing Radiative forcing, R, measures the influence of carbon dioxide in altering the additional solar ration trapped in Earth's atmosphere. The International Panel on Climate Change (IPCC) in 1990 estimated k to be 6.3 in the radiative forcing equation R = k In(), where Co is the preindustrial amount of carbon dioxide and C is the current level. (Data from Clime, W., The Economics of Global Warming, Institute for International Economics, Washington, D.C.) (a) Use the equation R = 6.3 In() to determine the radiative forcing R, in watts per square meter (W) to the nearest tenth, expected by the IPCC if the carbon dioxide level in the atmosphere doubles from its preindustrial level. (b) Determine the global temperature increase T, in degrees Fahrenheit to the nearest tenth, that the IPCC predicted would occur if atmospheric carbon dioxide levels were to double, given T(R) = 1.03R.
