Significant Figures Standardization

Does anyone know how standardized SigFig rules are? I understand that they are used in all respectable professional settings, but I was wondering how particular scientists are about certain rules, such as the "round to closest even number when at 5" rule.

Kp to Kc unit conversion

Is there ever a time that we'll be asked to convert Kp to Kc using units that aren't bar (or even atm)?

Finding The Direction of Reaction

Is there more than one way to find the direction of a reaction? Mathematically or otherwise.

Homework 17.37 Part d

Could someone help explain the solution to part d in 17.37? I understood the other parts of the question, but was confused when I saw that the solution (from the solution manual) for part d says that EDTA is hexadentate.

Acid Rain Damage [ENDORSED]

Does anyone know what is of the most concern regarding acid rain? I know that it is bad (and have a few examples of why), but what about it specifically causes such direct damage to an ecosystem?

Re: Are noble gases considered bases?

Keep in mind, too, that noble gases rarely react with anything (as I understand it) and so you also will not find noble gases forming or breaking bonds very often.

Radicals

Can someone explain the relationship between radicals and molecular shape? (In particular, how they are different/the same from lone pairs in determining molecular shape)

Resonance Structures and Molecular Shapes

Can anyone explain the relationship existing between resonance structures and their respective molecular shapes/orientations? I'm having a difficult time connecting the two concepts.

Electronegativity and Covalent Bonds

Can someone clarify exactly how electronegativity relates to whether or not a bond that forms is ionic vs covalent? I know that atoms with a greater difference in electronegativity tend to form covalent bonds, but I'm still struggling to explain to myself why that is.

Re: Covalent/ Ionic Bond

Also keep in mind that sometimes it can be difficult to determine which is which--there is a portion of bonds "in between" covalent and ionic bonds (due to differing, but still similar, attraction to electrons). In these cases, these bonds can (but don't always) exhibit behaviors of both.
