5.0 g of brass (Cp = 0.38 J/g-oC, initially at 68oC) and 3.5 g of aluminum (Cp = 0.9 J/g-oC, initially at 83oC) are dropped into 20 g of water (Cp = 4.184 J/g-oC, initially at 23oC). Based on the described system, which of the following statements is/are correct? Check all that apply. The water will evaporate. For each material, the heat involved is sensible heat. The equilibrium temperature will be greater than 23oC but less than 83oC. The temperature of the brass will increase. The temperature of the aluminum will decrease.
02:21 4G File Details 4CH003/UM1: Fundamentals of... Place a thermometer into the mixture and cool the flask in a water bath until the temperature is below 200C. Remove the flask from the water bath and carefully add cyclohexanol (10ml, 9.6g) to the acid mixture. Cyclohexanol is only slightly soluble in water so you should observe two immiscible layers at this point. Dissolve sodium dichromate dihydrate (10.5g) in water (5ml) in a 25ml conical flask and, using a dropping pipette, add this solution carefully drop by drop to the cyclohexanol/sulphuric acid mixture over about 30-40minutes. Swirl the flask vigorously during the addition process and maintain the temperature of the mixture in the round bottomed flask between 25-35°C during the addition by immersion of the flask in the cold water bath. If the dichromate solution is not added slowly, a rapid rise in temperature will occur and the reaction will become violent. 3 When all the dichromate solution has been carefully added rinse…
