Hi guys,
I found a video that illustrates how salts form acids and bases. Hope this helps!

Re: pKa vs Ka
Just as pH is a simpler way of understanding the concentration of hydronium ions, pK's are simpler way of understanding the equilibrium constants of weak acids or bases.

Formula for # electrons using Pi-bonds
Hi guys, just wanted to share a formula for figuring out how many pi-bonds must be used in a molecule and it goes like this: P(# of electrons that will use pi-bonds) = 6N + 2 - V where N is the number of individual atoms in the molecule, excluding Hydrogens and V is the total number of valence elect...

10, 12, or more electrons in extended octet?
How do we know if an element that can have an expanded octet will have 10, 12, or more electrons in that octet?

Re: Oxygen compounds (-ite vs. -ate)
Wait, correction: I read online that all -ate's have 3 oxygens except for sulfate and phosphate, which have 4 oxygens.
Furthermore, -ite's are all one less oxygen than the corresponding -ate so sulfite and phosphite will have 3 oxygens.

Oxygen compounds (-ite vs. -ate)
I know the suffixes -ite and -ate mean that a molecule is an oxygen compound (such as sulfite and sulfate) and that -ite's have the lesser amount of oxygen atoms between the two but how do we know how many oxygen's are involved? Is there a specific method to figuring that out?

Is it possible that two different arrangements have the same formal charge? In that case, would either arrangement suffice?

Re: Seesaw Structure question
So basically we should check if any other arrangement would put more space between the electrons than the one we come up with? And if there are none then it's good?

Can you apply the same logic to a relationship between electronegativity and atomic size? As in would more electronegative atoms be smaller in size?

T-shaped molecular geometry refers to AX3E2 in AXE notation meaning three bonding pairs around a central atom while also being repelled by two lone pairs.

Re: How does E = hv lead to Einsteins equation E=MC2?
I think the equations E=hv (mu) and E=mc 2 may be solving for two different energies. E=hv refers to the energy of a photon with respect to Planck's and frequency E=mc 2 uses the mass of an object and the speed of light. The first relates the energy of a photon (which doesn't have mass) while the se...

Re: Energy in kj or j when solving a problem?
I agree. Also, I would just set up the problem in the standard units of measurement (J for energy, nm for wavelength, etc.) to avoid multiple conversions down the road.

Example H.1
In the third step of balancing the equation for the combustion of C 6 H 14 + O 2 > CO 2 + H 2 O, the final balanced equation is C 6 H 14 + 19/2 O 2 > 6 CO 2 + 7 H 2 O... Why/how is the fractional coefficient used for O 2 19/2? Is there a specific method/formula for determining what fractions to use?

Re: Diffraction experiment for electron
I think the question meant to ask what characteristics* of a crystal cause electrons to diffract. I'm not entirely sure, but I think it's not so much that crystals have unique properties that make them refract photons and electrons-it's more that electrons just have less mass than the atoms in a cry...
