Assume that the complete combustion of one mole of ethanol to carbon dioxide and water liberates 1370 kJ/mol (?G°\' = -1370 kJ/mol). If the energy generated by the combustion of ethanol is entirely converted to the synthesis of a hypothetical compound X, calculate the number of moles of the compound that could theoretically be generated. Use the value ?G°\'compound X = -41.5 kJ/mol.
CH3OH burns in oxygen (O2) to from carbon dioxide (CO2) and water(H2O). Equal masses of ten grams of gaseous CH3OH and O2 are placed in an evacuated flask of five litres at the temperature of 25 degrees celsius.
