Calculate the energy change in kJ/mol for the reaction Li(g) + F(g) => Li+(g) + F-(g) (separated ions) using the following information:Li(g) → Li+(g) + e- +520 kJ/molF(g) + e- → F-(g) -328 kJ/molEnter your answer as the closest whole number with appropriate sign and without units.

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).
