"Translate the empirical molar enthalpy given below into a balanced chemical equation, including the enthalpy change (delta H):
The standard molar enthalpy of formation for carbon disulfide is 89.0 kJ/mol"

I got delta H = 178 kJ (is that right?). However, I'm having trouble knowing whether it's + or -.

  • Chemistry -

    C+2S>>CS2 Hf=+89.0kj/mole
