Question 50

During an experiment, water is added to 0.150 mol of white anhydrous copper(II) sulfate. Blue hydrated copper(II) sulfate forms and 11.7 kJ of energy is transferred to the surroundings.

The change is reversed by heating 0.425 mol of blue hydrated copper(II) sulfate.

Calculate the energy transferred when the hydrated copper(II) sulfate is heated.

State the direction in which the energy is transferred.
