PartB
Part A Hydrogen peroxide (H202) decomposes in the presence of a catalyst to form water and oxygen. The catalyst was added to 5 50 ml of a hydrogen peroxide solution at 250ãC, and 52.0 ml of gas was collected over water at a total pressure of 763.8 mmHg conditions in the table. Write and balance the chemical reaction (note: catalysts do not ap chemical equations) Express your answer as a chemical equation. Identify all of the answer. Look up the vapor pressure of water under these TABLE Vapor Pressure of Water versus Temperature Temperature ( c) Pressure Temperature (C) Pressure 2H202(aq) 2H20)+02(8) Submi Mv Answers Give Up (mmHg) (mmHg) 118.2 149.6 187.5 233.7 289.1 Correct 10 9.21 12.79 17.55 23.78 80 3186 42.23 55.40 71.97 70 Part B What is the partial pressure of oxygen collected over the water?
