A substance is combusted in the presence of oxygen within a bomb calorimeter. Using the diagram provided below, determine change in enthalpy and the direction (if any) of heat transfer.

Answer:
The change in enthalpy is positive
∆H = +
Explanation:
From the diagram above, we have a
substance combusted in presence of oxygen within a bomb calorimeter which implies that the reaction is endothermic (heat is conserved within the bomb calorimeter), this would make the enthalpy change to be positive.
