In a "kitchen chemistry" experiment, baking soda is added to vinegar in a flask and a deflated balloon is stretched over the mouth of the flask. Vigorous bubbling is observed, the flask feels colder, and the balloon inflates, as seen in the diagram below. The reaction that occurs is: NaHCO3 (s) + HC₂H3O2 (aq) --> NaC₂H3O2 (aq) + H₂O(l) + CO2(g) When this reaction occurs, heat flows primarily from the _ to the _ When this reaction occurs, work is done _ the system and wsystem is _
