Question

Tell which of the following are oxidation–reduction reactions. For those that are, identify the oxidizing agent, the reducing agent, the substance being oxidized, and the substance being reduced.
a. CH4(g) + 2O2(g) → CO2(g) + 2H2O(g)
b. Zn(s) + 2HCl(aq) → ZnCl2(aq) + H2(g)
c. Cr2O72-(aq) + 2OH-(aq) → 2CrO42-(aq) + H2O(l)
d. O3(g) + NO(g) → O2(g) + NO2(g)
e. 2H2O2(l) → 2H2O(l) + O2(g)
f. 2CuCl(aq) → CuCl2(aq) + Cu(s)
g. HCl(g) + NH3(g) → NH4Cl(s)
h. SiCl4(l) + 2H2O(l) → 4HCl(aq) + SiO2(s)
i. SiCl4(l) + 2Mg(s) → 2MgCl2(s) + Si(s)
