When do you use cis and trans?
Is it only when there is a double bond or can a triple bonded molecule have cis/trans?
Also, why is this molecule a trans?
Thanks!

Naming and Line structure 1.10
Give the systematic name for CH3CH2CH(CH3)C(CH3)3 and draw the line structure.
If the question only asked for name, could I use 1-tertbutyl-2-methylbutane? Or would the only name be 2, 2, 3-trimethylpentane?

Re: Work of Expansion [ENDORSED]
I'm not sure if this anywhere near what answer you were looking for, but .. I think for reactions that happen quickly (at infinitesimal changes), we can use w=-P_{ex}\cdot \bigtriangleup V . For reactions that happen more slowly, we use the integral (which is the cumulative sum of all the w=-P_{ex}\...

Re: All students read this sig fig post [ENDORSED]
Does it matter how many significant figures there are after the decimal while adding, multiplying, dividing, etc. ? (or does the number of significant figures of the result matter only?)
