Define while a sample of hydrogen sulfide (H2S) gas weighing 0.22 grams is burned in a bomb calorimeter with excess oxygen the temperature of the calorimeter rose from 25.00 to 39.47 degrees C. Explain if the heat capacity of the calorimeter and its contents was 24.571 Joule / degree C, from the data above, Define what is the value for burning 1 mole of the gas?
1) 54.95 kiloJoule/mol H2S
2) 55.89 kiloJoule/mol H2S
3) 52.13 kiloJoule/mol H2S
4) 53.1 kiloJoule/mol H2S
