1. (2 pts) The following reaction involves the hypothetical element Z: * Z2H4(1) + O2(g) → Z2(s) + 2 H2O(1) Use the following information to calculate AH° for the reaction. 2 ZH3(g) + 3 Z2O(g) → 4 Zz(s) + 3 H₂O(1) AH°=-953 kJ Z2O(g) +3 H2(g) → Z2H4(1) + H2O(1) AH°=-482 kJ 4 ZH3(g) + O2(g) → 2 Z2H4(1) +2 H₂O(1) AH°=-162 kJ AH° of H2O(l) = -285.8 kJ/mol

a) Learning units: Hospitals need compressed oxygen cylinders. Suppose you are given the choice of purchasing four oxygen cylinders: the red one (P = 2.0 atm, V = 34000 cm³), the blue one (P = 24 bar, V = 1.0 L), the green one (P = 22,000 Pa, V = 24 L), and a special yellow one with 1024 oxygen molecules. If they are the same the price, which cylinder should you purchase? Show your reasoning. Assume ideal gas behavior and the gases are at room temperature (25°C).
