In a “kitchen chemistry" experiment, a piece of raw liver is added to hydrogen peroxide in a bottle and a deflated balloon is stretched over the mouth of the bottle. Vigorous bubbling is observed, the flask feels warmer, and the balloon inflates, as seen in the diagram below. The reaction that occurs is: 2 H2O2(1) → 2 H2O(1) + O2(g) Note: catalase (an enzyme found in liver) speeds up the reaction but is not part of the reaction equation. When this reaction occurs, heat flows primarily from the v to the -- and the reaction is -- When this reaction occurs, work is done v the system and w is -- system
