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) +...
