10,800 kJ (per 2 moles of octane; the balanced chemical equation)
The change in enthalpy between products and reactants in a reaction
What is the delta H deg f of potassium?
hjh hjhjjh h
the delta h for x hydrogen and x chlorine because it is aq and dissociates in water into h+ ions and cl- ions
it means that heat is released during the reaction and a + delta H means that heat is required/absorbed.
0.0 KJ/mol
It is not. The density and mass would be used to find the volume.

I'm pretty sure its when the pressure remains constant. When the pressure is constant: q=delta U + P delta V The equation for delta H is: delta H = delta U +P delta V Therefore, when pressure is constant: delta H = q I think...
