cis versus trans
how can you tell if a molecule is cis or trans formation? For example if they give you a line structure.

determine how to draw the arrows
If you are given a reaction mechanism, how do you know how to draw the arrows showing electron movement? I understand that the electrons always move from nucleophiles to electrophiles, but I do not understand how you know which molecule or bond to draw each arrow from and to.

anode and cathode
given the half reactions from a table of reduction potentials, how do you know which one is the cathode and which one is the anode? if you assume that the e cell will be positive and name the cathode and anode accordingly is it always the case that the e cell would be positive?

determining half reactions
how do you know how many electrons, H+, and H20 to add to each side of the half reaction and to which side you add it to? is there a quick way of determining this?

most stable form
for the standard enthalpy of formation how do you know which state is the most stable form of each molecule? also what would you do if the molecules are not all in the most stable form? would the math be different in that case?

Heisenberg delta p and delta x
for the heisenberg equation do you plug in the +- number into delta x or the spread
ex. 20+-4m=16-24 range so would you put 4 or 8 into delta x
