This question asks for a fraction, a reduced fraction, and a mixed number. 2 Enter fractions like 2/3 for. For this type, the 2 fraction does not need to be reduced, so is 4 1 considered the same as For a reduced fraction answer, be sure to reduce 1 your fraction to lowest terms. If = is the correct 2 2 answer, is not reduced, and would be marked 4 wrong. For both fraction and reduced fraction type 10 problems,...
Question 19 5 pts In a coffee cup calorimeter, 6.70 g of NH.NO, is mixed with 75.0 g of water at an initial temperature of 25.0 °C. At the end of the dissolution, the final temperature of the mixture is 13.1 °C. With the assumption that the solution has the same specific heat capacity as water and is accompanied by no heat loss to the calorimeter, calculate the enthalpy change for the dissolution of NH.NO, in kJ/mol. C 47.2 80.1...
