Question: The combustion of 0 1584 g benzoic acid increases the temperature
The combustion of 0.1584 g benzoic acid increases the temperature of a bomb calorimeter by 2.54oC. Calculate the heat capacity of this calorimeter. (The energy re-leased by combustion of benzoic acid is 26.42 kJ/ g.) A 0.2130- g sample of vanillin (C8H8O3) is then burned in the same calorimeter, and the temperature increases by 3.25oC. What is the energy of combustion per gram of vanillin? Per mole of vanillin?
Answer to relevant QuestionsCombustion of table sugar produces CO2(g) and H2O(l). When 1.46 g of table sugar is combusted in a constant-volume (bomb) calorimeter, 24.00 kJ of heat is liberated. a. Assuming that table sugar is pure sucrose ...Given the following data: C2H2(g) + 5/2 O2(g) → 2CO2(g) + H2O(l) ΔH = –1300. kJ C(s) + O2(g) → CO2(g) ΔH = –394 kJ H2(g) + ½ O2(g) → H2O(l) ΔH = -286 kJ calculate ΔH for the reaction 2C(s) + H2(g) → C2H2(g) Given the following data: P4(s) + 6Cl2(g) → 4PCl3(g) ΔH = –1225.6 kJ P4(s) + 5O2(g) → P4O10(s) ΔH = –2967.3 kJ PCl3(g) + Cl2(g) → PCl5(g) ΔH = –84.2 kJ PCl3(g) + ½ O2(g) → Cl3PO(g) ΔH = –285.7 ...The space shuttle orbiter uses the oxidation of methyl hydrazine by dinitrogentetroxide for propulsion. The balanced reaction is 5N2O4(l) + 4N2H3CH3(l) → 12H2O(g) + 9N2(g) + 4CO2(g) Calculate ΔHo for this reaction. Syngas can be burned directly or converted to methanol. Calculate ΔHo for the reaction CO(g) + 2H2(g) → CH3OH(l)
