Δh for the formation of cucl2 from its elements is -220.1 kj/mol. how many kj are associated with the formation of 0.30 mole of cucl2? -66 kj -78 kj 85 kj 201 kj

Explanation:

Hello,

In this case, by knowing the enthalpy of formation of the copper (II) chloride is -220.1kJ/mol and there are 0.3 moles of such compound, the resulting whole energy is obtained by multiplying those values as the moles define the total energy as shown below:
