### Ring flip?

Does it matter whether the ring flip is flipped horizontally or vertically?

### Alkenes and alkynes?

So I understand that if we have an alkene (double bond) structure, we must include E or Z with the name. If there is no alkene and if there is an alkyne (triple bond) structure, do we also need to include E or Z with the name?

### Winter 2011 Final Q1C

Why is it that ethane has a higher heat capacity than ethene? I thought the more bonds in a molecule, the higher the heat capacity would be? And why does NO have a greater residual entropy at 0K than BF3?

### Re: Z, E vs. cis, trans

Z is the same thing as cis and E is the same thing as trans. Cis is on the same side and trans is on the opposite side. Good luck! :)

### Activation Energy Effect Clarification

Hi, I just wanted some clarification. So if the reaction has a higher activation energy, this would lead to a smaller k; would this also mean there would be a longer half-life and lastly, a slower reaction?

### 14.11(d)

I am confused with how to determine which elements will form whichever respective elements they do form? In this problem they give you Pt(s) | O2(g) | H+(aq) || OH-(aq) | O2(g) | Pt(s). More specifically, how do you determine which one is the oxidation reaction and which is the reduction reaction?

### Re: Acidic vs Basic

For these problems, are we always going to be given the conditions? (Whether the reaction is in an acidic or basic solution?)

### Textbook 9.37

For part a, when we balance the equation of formation of H2O(l), why do we balance it as H2(g) + 1/2 O2(g) ---> H2O(l) versus 2 H2(g) + O2(g) ---> 2 H2O(l)?

### Re: Required and Released Energy

I believe it has something to do with how if a bond is broken, it is always endothermic. It is always endothermic because more energy is required to break bonds than the energy needed to form bonds. (Products - reactants will come out to be positive)
