For each of the following redox reactions, determine which element is being reduced and which is being oxidized. (help it should be a one element answer!!) (a) MnO2(aq) + K2C2O4(aq) + 2 H2SO4(aq) → MnSO4(aq) + K2SO4(aq) + 2 CO2(g) + 2 H2O(l) element being reduced : Mn Correct: Your answer is correct. element being oxidized: ?? (c) 2 CrO3(aq) + 3 CH3CH2OH(aq) → Cr2O3(aq) + 3 CH3CHO(aq) + 3 H2O(l) element being reduced ?? element being oxidized ??

P = 0.44 MPa T = 108 kN•m h = 2.4mm Common Data: [Young’s modulus, E=210 GN/m2] [Poisson’s ratio, ν=0.33] [Yield stress σ0 = 210 MN/m2 ] Figure 1(A) through to (F) shows a pressure vessel. During a test program to determine its capacity, it is subjected to a combined internal pressure, P and torsion, T. The vessel has an external diameter, D = 1 m, length 3 m, and the wall thickness is h mm. Considering the wall is thin,...
