Answer:
Energy is released when bonds are broken, and energy is absorbed when bonds are formed.
The first thing we need to remember is that:
We have 7.54g of CuCl2 so we need to express this amount in moles dividing by the molar mass of CuCl2.
This is:
And, also remember that 65.0mL equals 0.065L.
Now, replacing in the molarity equation:
Thus the answer is 0.862M.
The correct option is A)
They overlap to form a pi bond

We are given with two set of conditions. To calculate the final volume, we get first the number of moles under the first condition. Using PV=nRT, the number of moles is equal to 0.16 moles. We substitute this together with the other conditions in PV=nRT, the final volume is 0.92 liters.
