Questions  1) Using the result from part (s) calculate the enthalpy change if you  neutralized six moles of HCl with an equal number of moles of NaOH. 2) Calculate the heat of neutralization of acetic acid in calories per milli-moles  3) Why is it important to perform this reaction in a Styrofoam cup? How might  your results change if you used two Styrofoam cups? Styrofoam is used in this experiment because it is a good insulator.  The plastic  foam contains billions of trapped gas bubbles. Gases hinder heat conduction

Unformatted text preview: because their molecules are very far apart making it difficult for other molecules to collide with them. When molecules DO collide, they either give or take away energy. (http://mmem.spschools.org/2F.9798/HotandCold/styro.html) 4) Why are you calculating H rather than H o ? H calculates the heat transfer meanwhile H o calculates change of enthalpy that accompanies the formation of 1 mole of a substance. We needed to find the heat absorbed from the different substances that we measured....
