REAL NAME - SHRESTH DUBEY
Answer:
250 kJ
Explanation:
Step 1: Given data
- Work performed by the system (w): 145 kJ (By convention, when the system performs work on the surroundings, w > 0)
- Heat absorbed by the system (q): 105 kJ (By convention, when the system absorbs heat from the surroundings, q > 0)
Step 2: Calculate the change in the internal energy of the system
The internal energy of a thermodynamic system is the energy contained within it. We can calculate the change in the internal energy (ΔE°) using the following expression.
ΔE° = q + w
ΔE° = 105 kJ + 145 kJ = 250 kJ
Members of a particular species living in a specific area is a population.
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.
