CHE201-71: General Chemistry and Quantitative Analysis I laboratory: Chapter 5 Recitation 1. When 1.025 g of naphthalene (C16H) burns in a bomb calorimeter, the temperature rises from 24.25 °C to 32.33 "C. The heat capacity of the calorimeter is 5.86 kJ/"C. Calculate: a) Gran per mole of naphthalene for the combustion process b) gran per gram of naphthalene for the combustion process Instant cold packs, often used to ice athletic injuries on the field contain ammonium nitrate and water separated...
GENERAL CHEMISTRY GROUP STUDY SB The first 3 problems are to be submitted today. #1.(30pts, 15 pts each) (c) Consider a 135 meter high waterfall. If the decrease in potential energy of the water (i.e., mgh) is totally converted into heat, calculate the temperature difference between the top and bottom of the waterfall. Data: m-mass, g- acceleration due to gravity 9.81 m/s. The specific heat of water- 4.184 J/(g "C). (d) If a system absorbs 30.0 J of heat from...
