Re: Midterm 2013 6a
The double bond would be on the 1st and 2nd carbon, not the 6. I also thought it would be 2, 3, 4, 4- tetramethylcyclo-1-hexene...

Re: Winter 2015 Midterm Question 2 and 3 D
Why is the value of standard enthalpy of reaction 42.00 kJ/mol for part C and D, but 84.00 kJ for part E? How do you know when to use the enthalpy value per mole?

Re: Van't Hoff Eq.
To get the Van't Hoff equation, why is the ln(K1-K2) equation multiplied by -1 on both sides to make it into ln (K2-K1)?

Re: Homework chapter 8 #3 part a [ENDORSED]
How do you know that pressure needs to be converted to Pa instead of kPa or another conversion? Is there a chart or other resource that tells me which units to use?

Re: Hess' Law [ENDORSED]
I am still slightly confused about how you know which reaction equation to flip the direction of when adding reactions to find the net reactions enthalpy change value. Will there ever be problems in which I need to make more than one flip of an equation to move the products and reactants to the side...
