What does it mean for a ring to be 8 membered?

Alina_Mitchell_2C

I think you can do this as long as there is only single bonds, cause if there is a double bond, you have to identify both where the double bond is and where the alcohol group is, so they both can't be put in the front

Why would the cell diagram for the redox reaction: 2Ag(s) + Br2 --> 2AgBr(s) have the cell diagram
Ag(s)|AgBr(s)||Br-|Br2|Pt?
Why are both AgBr and Br- included?

yes, but in a line structure, how do you know what is on the same side?

How can you tell whether two geometric isomers are cis or trans based on their line structures alone?

When we are naming a compound with functional groups, double/triple bonds, and multiple substitients, how do we choose where to start numbering the carbons?

For this question, why is it not enough to say that entropy is negative because two different substances are combining into one, so disorder is therefore decreasing. What more could have been said to get full credit on this question?

How do we know when Ecell is supposed to be positive or negative? Does it only have to be positive when it directly says that its a galvanic cell?

So in Problem 14.19, how come it gives you that the cell potential was found to be -0.689? Is there a reason why it is allowed to be negative here, but not in question 21?

How do you know when to use the positive or negative number for the anode? Is there a more definitive way than just choosing which ever way makes Eº positive?

For part a, I don't really understand how to balance this equation in a basic solution. How do you balance the H2O's and OH's?

Kira_Maszewski_1B wrote:What equation do we use for work in #3?

you use the equation w = -nRT ln (V2/V1) because the reaction is reversible and isothermal

How can you tell whether a question's answer is in kJ or kJ/mol? The solution manual seems to flip-flop between the two.
