Energy of hydrogen bonds

[joho]

Ok all you clever peeps, help me with this:

 

The bond energy of a hydrogen bond can be measured using chloroform and acetone....

 

1 using the equation E=m x s x θ, where E= energy, m= mass in grams of solvent, θ = temp change. TRUE OR FALSE

 

2. when acetone is not in molar excess TRUE OR FALSE

 

3. without any heat loss from the apparatus TRUE OR FALSE

Hey, take a moment and look this up in your textbook.

 

Let me see if I can help.

 

1 using the equation E=m x s x θ, where E= energy, m= mass in grams of solvent, θ = temp change. TRUE OR FALSE

This can't be true, I don't see the mole concept in the scene

 

2. when acetone is not in molar excess TRUE OR FALSE

No idea, this is practical, not conceptual

 

3. without any heat loss from the apparatus TRUE OR FALSE

Hell ofcourse true, 'cos if you lose all the heat then θ could be zero.

You will do a calorimetric titration of acetone and chloroform and get out the enthalpy of interaction, kcal/mole. That's no big whoop. Google has 18,900 hits on the experiment.

 

Me2CO and CHCl3 is a very trippy mix for all sorts of reasons, physical chemical and organic. Is yor TA taking care of the waste crock? Your mixed sovlent is explosive given a common contaminant added. What is the primary reaction and the amusing side reaction?

Its just a theoretical question, not an actual experiment I'm having to do. TG.:)
