In the reaction below, which substance is being oxidized?
Fe2O3 + 3CO -> 2Fe + 3CO2
CO
Fe
CO2
Fe2O3
Aircraft de-icing agents, such as propylene glycol [1,2-propanediol; CH₃CH(OH)CH₂OH; d=1.036 g/mL], are used toremove ice and snow prior to winter flights, but their presence inrunoff depletes O₂ in natural waters. (a) Write a balanced equa-tion for the complete oxidation of propylene glycol by O₂.(b) What is the “theoretical oxygen demand,” in grams of O₂ required per gram of propylene glycol oxidized? (c) What is thetheoretical oxygen demand, in grams of O₂ required per liter ofsolution, of 90.0% by volume aqueous propylene glycol?
Which substance is oxidized in each reaction?
a) 2Zn(s) + O2(g) = 2ZnO(g)
b) CH4(g) + 2 O2(g) = CO2(g) + H2O(g)
c) Sr(s) + F2(g) = SrF2(s)
