Thermodynamic quantities for selected substances at 298 k. A 2. 839-g sample of c2h4o was burned in a bomb calorimeter with a total heat capacity of. The temperature of the calorimeter increases from 22. 62 c to 26. 87 c. What is the heat of combustion per 1 mole of c2h4o: 299 kj, 4. 64 kj, 7. 20 105 kj, 8. 90 103 kj, 1. 10 103 kj. The specific heat of lead is 0. 13 j/gk. How many joules of heat would be required to raise the temperature of 15 g of lead from 22 c to 37 c: 0. 13 j, 5. 8 10 4 j, 560 j, 2. 0 j, 29 j. For a particular process q = +11 kj and w = +35 kj. = 0 kj/mol at 298k? f: c(s, graphite)
