Hi! Can anyone explain how to carry out chair flipping? Like how do you re-number it and know where to put the functional groups on the newly flipped structure?

I think we are expected to know all four: anti, gauche, slightly eclipsed, and fully eclipsed.

Will we be tested on chair/cyclohexane flips?

Professor Lavelle has announced that there will be no derivations on the final.

Will the final emphasize more on current topics? Or will the questions be evenly distributed across all topics?

For the quiz, are we expected to express the compounds through the skeletal/line-angle formula or through lewis dot structure?

Why is the answer for number 4, 4-butyl-1,2-dimethylcyclohexane and not 1,butyl-3,4-butylcyclohexane?

Hi! Why is the answer for number 4, 4-butyl-1,2-dimethylcyclohexane and not 1,2-dimethyl,4-butylcyclohexane?

When naming a compound, do the lower numbers do first?

I just checked the Bruincast and there hasn't been a correction made with the video uploaded :(

15.13 When 0.52 g of H2 and 0.19 g of I2 are confined to a 750.-mL reaction vessel and heated to 700. K, they react by a second-order process (first order in each reactant), with k = 0.063 L/mol*s in the rate law (for the rate of formation of HI). (a) What is the initial reaction rate? (b) By what f...

Okay thanks! That helps clarify things, but I was also wondering how each condition affects one's calculations for a certain reaction? And how it affects the temperature, pressure, etc

I'm also getting 1.21x10^-22 J/K.

What do the terms "reversible" and "irreversible" indicate about a reaction? And how do each affect calculations?

Hey! I was wondering if anyone could help me with this problem? 14.17 (a) Write balanced half-reactions for the redox reaction of an acidified solution of potassium permanganate and iron(II) chloride. (b) Write the balanced equation for the cell reaction and devise a galvanic cell to study the react...

Hi! I was wondering if anyone knew how to do this problem? Nanotechnologists have found ways to create and manipulate structures containing only a few molecules. However, orienting the molecules in specific ways to assemble such structures can be difficult. Calculate the entropy of a solid nanostruc...

Hi I was also wondering if someone could explain #7 and #9 on quiz one?

8.87) How much heat is required to convert a 42.30-g block of
ice at 5.042 C into water vapor at 150.35 C?

I was just wondering how I should start off solving this problem?

Hi! We went over enthalpy in lecture today and Professor Lavelle drew out a diagram as an example, but I am still confused on why enthalpy is a state function. Any help is appreciated!
