So we have learned that cyclohexanes are the most stable forms of "cyclo-" molecules out there because of there bond angles being 109.5 so there is little strain on the bond angles themselves. Can someone describe to me a real-life example on how we may be able to break long chains of cycl...

I am I correct in that when naming based on the IUPAC scheme, we take priority of the lowest number C bonded to the hydrocarbon groups and then after that (if the molecule is identical forward and reverse) we utilize the alphabetical order of the alkanes (ethyl take priority over methyl)? Or does th...

Dr. Lavelle used the example of 4 ethyl-2,2-dimethyl hexane in-class yesterday and I was wondering in a hypothetical scenario if we had 1 ethyl group (bonded at the 4th carbon atom) and 2 methyl groups bonded to hexane: 1 methyl group bonded to the 2nd carbon atom and another at the 3rd, how would w...

Can someone please describe to me how the units of each order of reaction differ, particular "k"'s units? Does it come from the derivation of the formula itself or is it dependent on the units of the concentration/pressure of the products and reactants in the equation? Any input would help...

In lecture, we learned about the model of a cathode-anode circuit, with electrons transferring from anode to the cathode. My question is how do we connect the circuit in order for it to be in a proper electrical loop. Why is it necessary to have a salt bridge with an aqueous substance like NaCl?

In the textbook, they described a transfer of energy from a particle of higher energy to one of lower energy upon collision when they are in an isolated container. Is this an example that can connect to thermal energy in that one substance of warmer temperature(i.e-coffee, water, etc) exchanges ener...

Hi there! I just was wondering about how altitude affects water's boiling points. I don't quite remember is it water's boiling point is lower at altitude? If so, why is that?

When I was reading Chapter 8, the book describes this idea of an "irreversible process" of pressure and how pressure cannot reverse a piston in a container. I am not quite sure what they are describing when they say "an infinitesimal change in external pressure does not reverse the di...

When we talked about how steam burns can be significantly worse than water burns at similar temperatures (Ex: 100 degrees Celsius), I was slightly confused on the math of the equation. Is the calculation for the steam burn a combination of both the heat change from the 100 degrees celsius to approxi...

Can someone please explain why as the Ka's increase in subscript, the attraction between opposite charges decrease? Is it because it is harder to separate the cation with the anion? I would love to know.

When we are given a negatively charged ion like O2- or BO-, where are we expected to put the extra valence electron? Is it on the more electronegative atom? And in the case of O2-, does it matter where we put it in the 2p orbital of the molecular orbital diagram?

Can someone tell me for molecular orbital theory why the sigma and sigma* or pi and pi* have different energy levels? Why would the anti-bonding orbital have more energy than the bonding orbital? Is because having a full orbital decreases its energy?

On our laminated periodic table, the group 11 metals (Cu, Ag, Au) all have an electron taken out of their s-orbital rather than their d-orbital for the electron configurations in their given spaces i.e-Cu: [Ar]3d10,5s1 Can anyone explain why it is noted the way it is? Also if I were to say for Cu, [...

In Chapter 2, the textbook defines an "ns-orbital" as "each shell has one-orbital, and the s-orbital in the shell with quantum number n." Are they referring to the donut-like shape of the s-orbital like Dr. Lavelle showed us in-class (aka the diagrams) for each n quantum number?

If the trend for atomic radii is shifting to right of a period and up a column to make it smaller, if we have two elements (such as Li and F) on the same periods, both with different atomic radii and orbitals pertaining to them, can we assume that the different energy levels of the orbitals affect t...

In the Lecture today (10/5), Dr. Lavelle talked about waves being described as taking on the form of sin- and cos- functions. Now when we graph sin- and cos-, they're usually on a two 2-dimensional graph with and the x and y axis. Are we assuming that the functions become 3-dimensional, or adding a ...
