A Carnot engine absorbs 100J of heat from a reservoir at the temperature of the normal boiling point of water and rejects heat to a reservoir at the temperature of the triple point of water.
Find the heat rejected, the work done by the engine, and the thermal efficiency.
21.54 mL of 0.2821M NaOH was titrated utilizing an unknown concentration of HCl. During you titration, you recorded an initial volume of HCl of 10.27mL as well as a final volume of 30.21 mL. Explain what is the molarity of HCl solution.
