The Nernst Equation

Q. Consider the cell described below: Zn|Zn^2+ (1.00 M)||Cu^2+(1.00 M)| Cu Calculate the cell potential after the reaction has operated long enough for the [Zn^2+] to have changed by 0.44 mol/L. (Assume T = 25 °C.) (This problem requires values in your textbook's specific appendices, which you can access through the OWLv2 Mindtap Reader. You should not use the OWLv2 References' Tables to answer this question as the values will not match.)

Orbital Overlap

Q. Thinking about electronegativity, match these chemical structures to their pictures ("electrostatic potential maps"-fancy!) Note that the images may have the molecules rotated a bit into different positions. Here's a hint: The O-H bond in each case is on the right side of both the picture and the Lewis structure.

Internal Energy

Q. Calculate w, and determine whether work is done by the system or on the system when 928 kJ of heat is released and ΔU = −1.47 × 103 kJ. (a)w = −1.36 × 106 kJ, done by the system (b)w = 1.36 × 106 kJ, done on the system (c)w = −5.4 × 102 kJ, done by the system (d)w = 2.4 × 103 kJ, done on the system (e)w = −2.4 × 103 kJ, done by the system
