Use the standard enthalpy change of formation data to calculate the standard enthalpy change of combustion of C5H12O.Data:C5H12O -283Kjmol-1CO2 -394kjmol-1H20 -286kjmol-1equation to use : C5H12O+7.5H2O ---> 5CO2+5H2O
Ethyl alcohol is produced by the fermentation of glucose, C6H12O6. Given that the enthalpy of formation is -277.7 kJ/mol for C2H5OH(l) and -393.5 kJ/mol for CO2(g)
Hydrogen can be extracted from natural gas according to the following reaction: CH4(g)+CO2(g) 2CO(g)+2H2(g) Kp=450 at 825K An 85 L reaction container initially contains kg of CH4 and 55.4 kg of CO2 at 825 K Assuming ideal gas behavior,
which effect on atomic size is more significant, the nuclear charge (p+) or the energy level that the eleectrons are filling explain why.
