Re: He2

The instability comes from the anti bonding regions being full. These regions offset those of the regular bonding regions and results in He2 being unstable.

Re: Poly vs. Mono [ENDORSED]

In a compound that is listed as monodentate, it means that that specific ligand only has a single binding site. This is in contrast to the polydentate ligands such as carbonato which can bind at multiple sites. In terms of naming, I do not think that they contribute any differently than any other co...

Re: Molecular Vs. electron [ENDORSED]

Electron geometry is the arrangement of electron groups (including atoms and lone pairs) while molecular geometry is the arrangements of atoms (excluding lone pairs). An example in class that explained this difference can be found on pg. 79 when talking about the molecule SO3(2-). With 3 bonding pai...

Re: The equals(=) sign or greater than (>) sign? [ENDORSED]

Hi Camila. Hopefully I am interpreting your question correctly... When using Heisenberg's Uncertainty equation, you should not have a change in the inequality sign to an equals sign. I think what you may be referring to (seen in pg.49 of the course reader) is when you can use the equation for moment...

Re: Preparing Stock Solutions Question [ENDORSED]

Hi Mekai! I think you would use the formula n(mol)=c(contentration)v(volume). (Make sure you use proper SI units.)
From there you would get the amount of moles needed, which you can turn into grams by using the molar mass of NaOH.
Hope that helps!
