    The energy required to convert one mole of hydrated copper (II) sulfate to one mole of anhydrous copper sulfate is 78KJ.
    How much energy is transferred to the surroundings when one mole of anhydrous copper sulfate is converted back into one mole of hydrated copper (II) sulfate?

    2) 178 kJ/mol is required for the forward reaction. What is the the energy transfer in the reverse reaction?
    B) If Calcium carbonate is heated in a boiling tube open to the atmosphere, the reaction goes to completion because the carbon dioxides can escape. Calculate the mass of carbon dioxide produced when 2.5 g of calcium carbonate is heated. (Mr CaCO3=100)

    Do you know the law of conservation of energy?
