Cameron Smith 1I

WOW ALEX A 99% IN BOTH 14A AND 14B CONGRATULATIONS!!!! I have a picgure for you but i am unsure how to attach it here. Job well done.

Cameron Smith 1I

I believe lewis os more broad so al bronsteds are lewis but a lewis cannot is not always bronsted.

Cameron Smith 1I

Why does pH depend on hydronium concentration and not hydroxide?

Cameron Smith 1I

What exactly does the term Bronsted imply?

Cameron Smith 1I

When determinong bond angles we can only guess that they areless than the accepted amounts when lone pairs are present.

Cameron Smith 1I

There are 5 regions of electrom density creating a trigonal bipyramidal e- arrangement. Since one region of e- density is a lone pair the result after the spacing out of the atoms and condensing of angles is a seesaw.

Cameron Smith 1I

Howndo we determine the arrangement of electrons based on the regions of electron density?

Cameron Smith 1I

What occurs when pi bonds are broken?

Cameron Smith 1I

What are the energy levels of hybrid orbitals in comparison to other orbitals?

Cameron Smith 1I

In terms of hybridization pi bonds (more than a single bond) would imply that there are other orbitals besides the hybridized orbital.

Cameron Smith 1I

How would we know which of the bonds is a pi bond when we have more than a single sigma bond?

Cameron Smith 1I

IM pretty sure whenever there is an odd number of electrons to distribute there will bw a radical, but I am not positive how to determine which element will be the radical.

Cameron Smith 1I

The closer the distance between the electronegativities is to 2 then the bond has more ionic character. The closer the distance between the electronegativities is to 1.5, the bond has more covalent character.

Cameron Smith 1I

It is important to remember that electron affinity and ionization energy are both taken into account when determining electronegativity of elements.

Cameron Smith 1I

When do we place brackets around ions?

Cameron Smith 1I

Elements from the 3rd period and below can break the octet rule and acquire more than 8 valence electrons (an octet) due to the presence of the d orbital.

Cameron Smith 1I

How do we determine which atom or ion can be classified as the radical?

Cameron Smith 1I

Why can hunds rule be broken in the excited state? What does the excited state imply?

Cameron Smith 1I

Also why do cations in the d block lose their s orbital electrons before their d orbital electrons?

Cameron Smith 1I

Would it be safe to say that the elements in the same group as copper and chromium follow the same rules in terms of electron configuration?

Cameron Smith 1I

When dealing with anions and cations how do we distinguish their electron configurations from other elements?

Cameron Smith 1I

What is characteristic of electrons that are parallel?

Cameron Smith 1I

If the 3d state is higher in energy then why is it that we write it first before the 4b orbital in the electron configuration?

Cameron Smith 1I

Would there ever be any instance in which a particle can exist beyond its range of uncertainty?

Cameron Smith 1I

The energy levels (n) of electrons are discrete but is there any way in which we can describe the electron's existence between levels?

Cameron Smith 1I

Does the level of conductivity of the metal influence the photoelectric effect in any way?

Cameron Smith 1I

How would we create the balanced equation if we are told that there is an additional product besides CO2 and H2O in a combustion reaction?

Cameron Smith 1I

What occurs to the kinetic energy that is the excess when the energy of the photon is greater than the threshold energy?

Cameron Smith 1I

Would there be any instance in which light acts as a wave but not a particle?

Cameron Smith 1I

As many have noted above moles mols and mol can all be used when referring to moles, but it is important to not that M (capital) is not just for molar mass, but is also for molarity.

Cameron Smith 1I

In this course will we be forced to convert between Celsius and Fahrenheit? If so what significance would this hold?

Cameron Smith 1I

When showing our work will we lose points if we do not show how the units cancel out throughout the problem and just provide numbers and the final correct units?

Cameron Smith 1I

How do we distinguish between M for molar mass and M for molarity?
