Propose a method for determining the specific heat for a metal like sodium that reacts with water?
q = mass x specific heat x delta T.
Could you weigh an amount of Na metal, let it react with a known mass of water, measure delta T of water for the heat of reaction, and you know specific heat of water? That would give you q for the mass of Na reacted. Check my thinking.
what about caloriometry? Use a caloriometer and find the temperatures with a digital thermometer. You need to take the water and find the initial temperature, then add the sodium and then mix the sodium in there until it is fully dissolved and then measure the new temperature. I cant remember what to do after that, but that is a start! Search calorimetry on the internet (I may have spelled it wrong) Hope that helps! Sorry if it doesn't!
yes you use the equation that was posted in the answer before mine...there you go!
ok thank you, we're doing thermochemistry right now, so we actually just did that calorimeter lab yesterday, and we've been using that equation.. i don't know if my teacher wants us to use methods we already know.
You CANNOT USE WATER!!! Sodium EXPLODES in water! You must use an oil or xylene
