Re: pKb and pKa

When looking at an equation say HCOOH + NaOH =(equilibrium sign) HCOO- + Na+ +H20, how do you know if the reaction priiduces Ka or Kb?

Re: MO diagrams for ions

In MO diagrams, is it required that we always include the atomic orbitals?

Re: Drawing MO Diagrams

When drawing molecular orbitals, what do the antibonding regions actually mean ? I understand the wave functions are out of phase but conceptually how do we picture this?

Re: Resonance vs. Lewis Structure?

You will more than likely be asked specifically to draw a resonance structure, you won't typically know to do it on your own without instruction. However, when drawing lewis structures even if there is resonance you should simply draw the one with the lowest formal charges if the question doesn't in...

Re: Dipole and Polarity [ENDORSED]

So does this mean that if an element is more electronegative it has a slightly negative charge?

Re: Balancing Equations

Hello! Just like the posts before, the rules for balancing equations are uniform across different states of compounds. However in a situation where you need to write the equation yourself before balancing it, it would be helpful to know the subscripts of elements in the state given. For example many...

Re: Work Function and Threshold Energy [ENDORSED]

Hi Daniela! To my understanding the work function is the minimum amount of energy needed to remove an electron from a metal surface, this means that every individual metal surface has its own specific and uniform work function. While on the other hand, the threshold energy is the specific frequency ...

Quiz 1, Preparation 2, Q1

Hi! For this question
"How many grams of NaOH do you need to prepare a 3.0 x 10^2 mL stock solution of 2.00 M NaOH?
How does the set up begin for this?
