Calculate the Molar Heat of Combustion of Ethanol, when 20 g of ethanol was combusted in a calorimeter with excess oxygen. The heat given off in the calorimeter raised the temperature of 1 kg of water in the calorimeter from
19-33\deg C. The specific heat capacity of water is
4.2Jg^(-1)KExplain Hess's law and use it to Calculate the
\Delta Hfor the following equation:
CO(g)+2H_(2)(g)->CH_(3)OH(g)Given the following equations:
2CO(g)+O_(2)(g)->2CO_(2)(g),\Delta H=-566kJ
2H_(2)(g)+O_(2)(g)->2H_(2)O(g),\Delta H\deg =-571kJ
2CH_(3)OH(g)+3O_(2)(g)->2CO_(2)(g)+4H_(2)O(g),\Delta H\deg =-1430kJ
