. Assign oxidation numbers to each of the atoms in the following reactions and determine if the reaction is redox. If it is, identify the atom oxidized and the atom reduced. 1. H2(g) + F2 (g) -> HF (G) un 2. SiO2 (s) + C(s) -> Si (s) + CO (9) s() 3. S2032 (aq) + 12 (aq) -> $4062- (aq) + 1" (aq) 4. HCl(aq) + NaOH (aq) -> H20 (aq) + NaCl (aq) 5. CH4 + NO2-> N2 + CO2 + H2O
