Iodine is the reducing agent in the following balanced redox reaction: I2 (s) + 5 Cu2+ (aq) + 6 H2O (l) → 2 IO3- (aq) + 5 Cu (s) + 12 H+ (aq)

Using the standard reduction potentials document, calculate the cell potential at 25 °C for the following voltaic cell: Cd (s) | Cd2+ (aq) || Sn2+ (aq) | Sn (s)

Consider the following balanced redox reaction: Cr2O72- (aq) + 6 I- (aq) + 14 H+ (aq) → 2 Cr3+ (aq) + 3 I2 (s) + 7 H2O (l) Which element was reduced during this reaction?

  When subjected to wind perpendicular to the ridge, the windward roof is subjected to a pressure of -13.3 psf and the leeward roof is subjected to a pressure of -9.9 psf.  Assume both of these pressures are uniform over the entire length of building (60 ft).  For an interior truss, the value of P3 is nearly
