38 Question (4 points) Answer the four questions below regarding an electrochemical cell in an automotive lead-acid battery. The cell's anode is made of lead and the cathode is made of lead(IV) oxide. Both are submerged in 4.40 Msulfuric acid. The half-reactions are: $PbO_2(s) +3H^+(aq) + HSO_4^-(aq) +2e^- \longrightarrow PbSO_4(s) +2H_2O(l) \quad E° = 1.685 V$ $PbSO_4(s) +H^+(aq) +2e^- \longrightarrow Pb(s)+HSO_4^-(aq) \quad E° = -0.356 V$ 16th attempt Part 1 (1 point) Calculate the value of $E°$. 2.041 V Part 2 (1 point) Determine the initial value of $E_{cell}$. Assume that the first ionization of $H_2SO_4$ is complete and that $[H^+] = [HSO_4^-]$. 2.1173 V Part 3 (1 point) Find $E_{cell}$ when the $H^+$ concentration has dropped by 89.00%. Again, assume $[H^+] = [HSO_4^-]$. 2.0605 V Part 4 (1 point) By what percentage has $E_{cell}$ decreased? %

Question 1 1 pts Which of the following statements correctly distinguishes capitalism from socialism? Under capitalism, \"how to produce\" is determined by business people's desires to minimize cost and maximize profits; in socialism, it is determined to a much greater degree by government. There is more freedom of enterprise in socialism than in capitalism. Under capitalism, \"what to produce\" is determined by consumer demand; in socialism, by free market forces. Capitalism still exists while socialism no longer exists in any form.
