Question

Determine whether or not each reaction is a redox reaction. For those reactions that are redox reactions, identify the substance being oxidized and the substance being reduced.;a. Zn(s) + CoCl2(aq) - ZnCl2(aq) + Co(s);b. HI(aq) + NaOH(aq) - H2O(l) + NaI(aq);c. AgNO3(aq) + NaCl(aq) - AgCl(s) + NaNO3(aq);d. 2 K(s) + Br2(l) - 2KBr(s);98. Consider the unbalanced redox reaction;Cr2O7(2-)(aq) + Cu(s) - Cr3+(aq) + Cu2+;Balance the equation in acidic solution and determine how much of a 0.850 M K2Cr2O7 solution is required to completely dissolve 5.25g of Cu.;Additional Requirements;Other Requirements: Needed IMMEIDATELY
