What does Hess's Law state? | Hess's law states that the total enthalpy change of a reaction is always the same, no matter which route is taken |
TRUE OR FALSE: The enthalpy change of formation for all elements is zero | TRUE The element's being formed from that element, so there's no change in enthalpy |
