Thermochemistry Lab: Need help on finding a suitable double displacement reaction

1. Oct 29, 2006

Well, my chemistry teacher is extremely confusing, and wants us to create our own lab where we figure out the enthalpy changes in a chemical reaction. Is there are reaction out there that would give a considerable change in temperature, while using chemicals typically found in a high school? As an aside, he also gave us an option to

Here's what I've come up with so far... it would be great if I could get some feedback on these reactions.

1. $$Mg_ (s) + HCl_ (aq)$$

(Last resort, because my teacher recommends a double displacement reaction)

2. $$NaOH_ (aq)+ HCl_ (aq)$$

(Another last resort, because my teacher recommends a double displacement reaction)

3. $$CuSO_4_(aq) + 2NaCl_ (aq)$$

(I have no idea if there's going to be any heat change from this)

Any help on this would be fantastic and very much appreciated!

Thanks,

You can perform a simple calorimetry experiment, have you been exposed to this concept so far?

sulfuric acid to sugar is really fun... is that a double replacement... I'd have to think... but it does let off a lot of heat... and the charred black mess is awesome.

Edit: they are calling it a "DEHYDRATION/HYDRATION" reaction:

Neutralization should be OK - enough heat to measure and concentrations of reactants easy to check.
