A piston-cylinder, initially containing 200 mol of helium at 300 K and 0.1 m3 , is expanded to 5 times its original volume by applying 1.5 MJ of heat from a hot reservoir at 400 K. Assuming helium is a van der Waals fluid and with C ∗ P = 29 J/(mol·K), determine the maximum work that can be produced from this process. What is the final temperature of the gas?

During trial 2, what allowed you to determine that aluminum was the limiting reactant? check all that apply. all of the copper dissolved. all of the aluminum dissolved. the solution turned clear. the number of grams of copper(ii) chloride used in the reaction was greater than the number of grams of aluminum. the molar ratio of copper(ii) chloride to aluminum was greater than 3: 2, the equation’s molar ratio.
