The oxidation of copper(1) oxide, Cu,O(s), to copper(II) oxide, CuO(s), is an exothermic process. 2 Cu,O(s) + 0,(g) → 4CUO(s) The change in enthalpy upon reaction of 48.73 g Cu,O(s) is --49.72 kJ. Calculate the work, w, and energy change, AUpa, when 48.73 g Cu,O(s) is oxidized at a constant pressure of 1.00 bar and a constant temperature of 25' C. Note that AEa is sometimes used as the symbol for energy change instead of AU. kJ AU = kJ

Question
The oxidation of copper(I) oxide, Cu,O(s), to copper(I) oxide, Cu0(s), is an exothermic process. 2 Cu, O(s) + 0,(g) –→ 4 CuO(s) The change in enthalpy upon reaction of 48.73 g Cu, O(s) is -49.72 kJ. Calculate the work, w, and energy change, AUna, when 48.73 g Cu, O(s) is oxidized at a constant pressure of 1.00 bar and a constant temperature of 25' C. Note that AEan is sometimes used as the symbol for energy change instead of AUan . w = kJ AUIn = EXI kJ
