Question 1

What is the relation between joules (J), volts (V), and coulombs (C)?
◦ 1 J = 1 V × 1 C2
◦ 1 J = 1 V × 1 C
◦ 1 J = 1 C ÷ 1 V
◦ 1 J = 1 V ÷ 1 C

Question 2

The cell reaction for a dry cell battery is

Zn(s) + 2 MnO2(s) + 2 NH4+(aq) → 2 NH3(aq) + Mn2O3(s) + Zn2+(aq) + H2O(l).


The standard cell potential for this cell is 1.56 V. What is the standard free energy change for this cell?
◦ +151 kJ
◦ -301 kJ
◦ -602 kJ
◦ -151 kJ

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
