Which of the following is a statement of Hess's law? O The AH of a reaction depends on the physical states of the reactants and products. O If a reaction is carried out in a series of steps, the AH for the reaction will equal the sum of the enthalpy changes for the individual steps. O The AH for a process in the forward direction is equal in magnitude and opposite in sign to the AH for the process in the reverse direction. O The AH for a process in the forward direction is equal to the AH for the process in the reverse direction. O If a reaction is carried out in a scrics of steps, the AH for the reaction will equal the product of the enthalpy changes for the individual steps.

The gas-phase reaction between nitrogen and oxygen was carried out in a device designed to maintain constant pressure. Write the balanced chemical equation for the reaction between nitrogen oxygen. Include physical states. balanced equation:
Under what conditions will the quantity q be a positive number and the quantity w be a positive number? Oq is positive when the system loses heat to surroundings, w is positive when the surroundings does work on the 4 system. qis positive when the system loses heat to surroundings, w is positive when the system does work on the surroundings. qis positive when the system gains heat from surroundings, w is positive when the surroundings does work on the system. O qis positive when the system gains heat from surroundings, w is positive when the system does work on the surroundings.
