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.

The yield of a chemical process, expressed in percentage of the theoretical maximum, is measured with each of two catalysts, A, B, and with no catalyst (Control: C). Five observations are made under each condition. Making the usual assumptions for an analysis of variance, test the hypothesis that there is no difference in mean yield between the three conditions. а.

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
