Hydrogen peroxide, H₂O₂, has a density of 1.45 g/cm³ and decomposes spontaneously but slowly. The decomposition reaction will proceed at a faster rate if iodide ion, a catalyst, is added. The steps for the catalyzed reaction are: H₂O₂(aq) + (aq) → H₂O(l) + Ol-(aq) H₂O₂(aq) + Ol(aq) → H₂O(l) + O₂(g) + (aq) a. What is the net reaction? b. If 10.00 mL of H₂O₂ undergoes this reaction, what mass of oxygen is produced? c. If the reaction has an 85.5% yield, what mass of oxygen is actually produced?

Initially, only A and B are present, each at 2.00 mol · L. What is the final concentration of A once equilibrium is reached? Express your answer to two significant figures and include the appropriate units.

In biological systems, acetate ion is converted to ethyl alcohol as follows: CH3COO–(aq) + 3 H+(aq) + 2e– ----> CH3CHO(aq) + H2O E° = –0.581 V CH3CHO (aq) + 2 H+(aq) + 2e– ------> C2H5OH(aq                                                                   E° = –0.197 V Find E° and ∆G° for the overall process.
