Determine which element in each reaction is undergoing OXIDATION and which element is undergoing REDUCTION. Enter the element symbol only (capitalization counts). Do not enter any charges. Cr2O7(aq) + 3 Sn2+(aq) 14 H+(aq) → 2 Cr3+(aq) + 3 Sn4+(aq) + 7 H2O(l) Oxidation = Blank 1 Reduction = Blank 2 Cu2+(aq) + Zn (s) → Zn2+(aq) + Cu(s) Oxidation = Blank 3 Reduction = Blank 4 4 Fe3+(aq) + H2O (l) → 4 H+(aq) + 4 Fe2+(aq) + O2 (g) Oxidation = Blank 5 Reduction = Blank 6 2 Al (s) + 3 H2O (l) → Al2O3 (s) + 3 H2 (g) Oxidation = Blank 7 Reduction = Blank 8

Texts: modeled by the function Dt = 35.626t + 71.831, where t is the number of years since 2009. Find the country's national credit market debt, Dt, since 2009, given that D0 = 2526.263. The country's national credit market debt since 2009, in billions of dollars per year, is given by Dt = (Do + 35.626t + 71.831). (Do not include the $ symbol in your answer.)
