Is the following a properly written thermochemical equation?

2C8H18 + 25O2 → 16CO2 + 18H2O, ΔH = –5,471 kJ/mol

No, the equation does not list the enthalpy of reaction.

Yes, the equation is correct.

No, the equation does not list the states of each substance.

No, the equation is not balanced.

  1. Properly written? Looks not so "proper" to me. Technically, it should have states of the compounds, otherwise, it is ok
