Thermochemistry Lab Hypothesis We predict that two different physical changes (dissolving of a chemical substance in water) will produce energy changes; one exothermic and one endothermic. We predict that the temperature change will be affected by the change in system (open vs. closed) will be as follows: the temperature change in the closed system will be greater than that of the open system.

Simple and Fractional Distillation Experiment II Stancy Saji‚ 18 September 2014 Purpose Experiment II involved two kinds of distillation techniques: simple and fractional. Simple distillation was done to separate ethyl acetate—which has a usual boiling point of 77º—from a less volatile component‚ while fractional distillation was done to distinguish an ethyl acetate/n-butyl acetate mixture‚ which has boiling points of 77º and 125 º‚ respectively. Results and Discussion As previously stated the
