Question details

Name Section Experiment 14 Advance Study Assignment Heat Effects and Calorimetry 1. A metal sample weighing 147.90 gand at a temperature of 99.5 C was placed in 4973 g of walerin a calo. rimeter at 230C. At equilibrium the temperature of the water and metal was 41,8ac. a What was ar for the water? Ar b What was at for the metal? How much heat flowed into the waieraake he specific heat the water o be c) d calculate the specific heat of the metal, using Equation 3. Joules/g C e. What is the approximate molar mass ofthe metal? (Use Eq. 4) Romol 2. When 498g of NaoH was dissolved in 4972 gof water in a calorimeter at 23.7 C, the emperature of the solution went up to 50.1 C. a. Is this dissolution reaction exothermic? Why? b. Calculate using Bquation l. joules c. Find AH for the reaction as it occurred in the calorimeter (Eq. 5). joules (continued on following page)
