- official UT ID card (with your picture and name on it)
- a simple scientific calculator (not a graphing calculator)
- a pencil(s) and eraser
- memorized formulas in your head - not on paper or anything else
- nothing else is allowed

- A printed copy of the exam (every exam has a unique version number on it).

**reduction** = the gain of electrons (ox# decreases)

**oxidation** = the loss of electrons (ox# increases)

**cathode** = the electrode where reduction occurs red cat

**anode** = the electrode where oxidation occurs an ox

shorthand cell notation

anode \(\bigl|\) anodic solution \(\bigl|\bigl|\) cathodic solution \(\bigl|\) cathode

\(E^\circ_{\rm cell} = E^\circ_{\rm cathode} - E^\circ_{\rm anode} \)

\(\Delta G^\circ = -nFE^\circ\)

\(\Delta G^\circ = -RT\ln K\)

\(nFE^\circ = RT \ln K\)

\(E = E^\circ - {RT\over nF}\ln Q\)

\(E = E^\circ - {0.05916\over n}\log Q\)

\(\displaystyle{I\cdot t\over n\cdot F} = {\rm moles} \)
