What mass of ethanol (C₂H6O), when combusted completely, will heat 250 mL of water from 15°C to 20°C? AHrxn = -1300 kJ Calculate the AHrxn for 4 NO(g) + 6 H₂O (1)→ 4 NH3 (g) + 5 O₂ (g) If production of 50.00 grams of oxygen causes 15.00 L of water to cool from 50°C to 45°C. 5. When .514 g of C12H10 undergoes combustion in a bomb calorimeter, the temperature increases from 25.8°C to 29.4°C. The heat capacity of the bomb and all of its contents is 5.86 kJ/°C. a. What is the heat released per mole of C12H10? b. Is the number you calculated AE or AH? Why? C. Is AE = AH for this reaction? Why? Balanced reaction: 2 C₁2H10 (s) + 29 O₂ (g) → 24 CO₂ (g) + 10 H₂O (g) d. If AE and AH are not equal, which one is more negative? Why? 3. 4.
