You'd think that atoms bonding with other atoms would mean they're being friendly, but really they steal each other's electrons.
How ionic.

Re: When to flip a half reaction
When you look at the standard reduction potentials compare the two values. Proceed to flip the half reaction that will give you the highest positive cell potential. Remember that when you reverse a reaction, the sign of the reduction potential is also reversed.

Standard Enthalpy
The course reader says that the standard enthalpy of formation of an element in its most stable form is 0. Is that why the enthalpy of O2 in the combustion of methane: CH4(g) + 2O2(g) --> CO2(g) = 2H2O(l) is 0? Why is this the case?
