Dear Dr. Lavelle, Thank you for being a great professor. The way you teach chemistry is very concise and insightful which helps facilitate faster understanding of the topics. In addition, the puns and jokes you make while teaching makes it all the better. Thank you again for teaching us chemistry. B...

Yes, that is correct and also to break through that boat formation the collision has to be strong enough to break through the energy barrier in order for it the ring flip to occur.

From what I've remember in class what I can recall is that he touched on lewis acid and bases, hybridization, and vsepr models. But these things he mentioned briefly so I'm not entirely sure if we really need to know them and sorry I can't recall the page numbers. There might be others things to tha...

Yes! for your first question. After looking it up, its called a cyclo when it is joined up in any ring.
This is the site I got it from http://www.chemguide.co.uk/basicorg/con ... names.html if you look for the cyclo info you can get a more depth explanation of it.

I think usually we should be given some sort of information for us to determine which is the slow or fast step; whether they tell us straight up that one is fast the other slow or through the k's and the larger one is the faster step.

If you look on page 59 starting where it says "Think about this, if you want to write...", it basically starts from saying the rate of the reactants is equal and opposite of the rate of the products. So then we apply the problem above and the reaction for that particular one and from that ...

I think like the first quiz we took we will be given them in the question or on a separate sheet like the formula sheet.

Hey, I am interested to study for the midterm. I was thinking meeting up on Sat to work on practice problems and then going to review session on Sunday??

When are we allowed to use this? under what circumstances do we use this? (refer to equation above)

You could always find a study group or form one to work with or find tutoring like AAP.

The reason Professor Lavelle called it "favorable" because it's spontaneous; meaning the reaction is moving in a way that is "favorable" or in the natural direction. Like the example he gives with a rock in a valley. If the rock is on the edge, its rolling down the hill naturally...

I think it's always safe to know significant figures and plus I heard for Lavelle's class he emphasizes a lot on sig figs. So I recommend you to review them.

I think using the equation for q=(n) (Cv,m) (delta T) is the best for this question because it's asking to find the change in heat and the equation does just that. For the C values I'm pretty sure we will have to be given those values to solve the problem using the equation above. And [ deltaH = del...

If you recall on the first day of lecture, the sub taught us about the basics of physical or phase change of water from a solid, liquid, and finally a gas. To get to a certain state, change in heat is required. Let's say we have some hot water that's coming to a boil and its at 30 degrees Celsius( t...

Hey, Marco interesting question. I looked more into it and in the textbook itself Section 8.10 pg 280-281 it gives the whole explantion on why for constant volume its (3/2)R and for constant pressure its (5/2)R. Hope that helped! and yes I assuming we should know these numbers.

Danny Nguyen 2H

Isn't it because it's in its natural state in the world so it's formula is that way. For your example N, nitrogen, exists in the real world as a gas, N2. Similar to the example given in lecture, oxygen exists in the real world as O2.
