    Heat Transfer Reaction: CH3OH to CO + H2

    Heat Transfer! Consider the following reaction: CH3OH(g) -> CO(g) + 2H2(g) Change in H= +90.7 kJ (a) Calculate the amount of heat transferred when 45.0 g of CH3OH(g) are decomposed by this reaction at constant pressure. (in kJ) (b) If the enthalpy change is 14.0 kJ, how many grams of...

    Heat of combustion for quinone (C6H4O2) in a bomb calorimeter

    I am needing help on some homework questions: A 2.200 g sample of quinone, C6H4O2, is burned in a bomb calorimeter whose total heat capacity is 7.854 kJ/ degrees C. The temperature of the calorimeter increases from 23.50 degrees C to 30.63 degrees C. 1. What is the HEAT OF COMBUSTION PER...
