Below is a set of redox reactions. Assign oxidation numbers below each atom. Also determine the substance that is reduced, the substance that is oxidized, the oxidizing agent, and the reducing agent. (Note: Don’t worry about the stoichiometric coefficients; they don’t affect your calculation of oxidation states.) Atom/s that is/are reduced: Atom/s that is/are oxidized: Reducing agent: Oxidizing agent: Reactions Given: 2 C2H6(g) + 7 O2(g) → 4 CO2(g) + 6 H2O(g) C2H4(g) + 3O2(g) → 2 CO2(g) + 2...

Problem 2: Below are several chemical equations. For each equation, identify which atoms are oxidized and which atoms are reduced. It is possible to have a type of atom that is both oxidized and reduced in the same chemical process. (How? Assign oxidation numbers to each element on both sides of the equation. If the number goes up, the atom is oxidized. If the number goes down, it's reduced.) a. N2(g) + 2 O2(g) → 2 NO2(g) b. CH4(g) +...
