In this reaction, we combine 5.85 g of 63.7 ºC water with 6.63 g of 18.9 ºC water in a calorimeter. Since some of the heat is absorbed by the calorimeter, the final temperature of the water is 28.8ºC. Since the hot and cold water are combined, the final temp of the water is the final temp for the hot water and the cold water. Calculate the heat change of the calorimeter in J. Remember that all of the heat changes must add up to zero so you can calculate the heat change of the hot water (qhotwater) and the heat change of the cold water (qcoldwater) using for each where Cs = 4.186 J/gºC. The first law of thermodynamics tells us that all of these changes sum up to zero so Enter your answer to one decimal place (tenths)arrow_forwardA student determines the heat of dissolution of solid potassium bromide using a coffee-cup calorimeter of negligible heat capacity.When 4.93 g of KBr(s) is dissolved in 108.00 g of water, the temperature of the solution drops from 25.00 to 23.11 °C.
