Chemistry · Secondary 4 · Medium · Bond energies
The combustion of hydrogen is represented by:
.
Using the bond energies: H–H = 436 kJ/mol, O=O = 498 kJ/mol, O–H = 463 kJ/mol, calculate the energy released when 1 mole of hydrogen gas is completely burned.
.
Using the bond energies: H–H = 436 kJ/mol, O=O = 498 kJ/mol, O–H = 463 kJ/mol, calculate the energy released when 1 mole of hydrogen gas is completely burned.
- 241 kJ released
- 241 kJ absorbed
