What is the work done by the copper bar on the surrounding atmosphere? The density of copper at 20 degree celsius is equal to 8920 kg/m3.
Compare the amount of A extracted by two extractions using 50 mL of diethyl ether each to the amount extracted by a single 100 mL extraction of the ether. Which is more efficient?
Consider the equation A(aq) + 2B(aq) -> 3C(aq) + 2D(aq). In one experiment, 45.0 mL of 0.050 M A is mixed with 25.0 mL 0.100 M B. At equilibrium the concentration of C is 0.0410 M. Calculate K.
