WebMar 13, 2024 · The heat of formation for liquid H2O is –285.83 kJ/mol and for CO is –110.53 kJ/mol, and the heats of formation for the elements H2 and C are both 0 kJ/mol. If you have a reaction with more than one molecule of a given compound, multiply the heat of formation value by the number of molecules of that particular compound in your reaction. WebThe joule has base units of kg·m²/s² = N·m. The base unit conversion can be remembered using the equation E = mc 2, where E is in joules, m is in kilograms, and c is the speed of light in meters per second. Type the number of kJ you want to convert in the text box, to see the results in the table. 1 kJ is equal to 737.58 foot-pound Metric kWh
