Web25 de jan. de 2024 · Some moderately reactive metal oxides are reduced by using carbon as a reducing agent. In this reduction process, the metal oxide is mixed with carbon in the form of coke and heated in the furnace to form carbon monoxide \ (\left ( { {\text {CO}}} \right)\). Thus, the metal oxide is reduced to metal. WebA The possible reduction products are Mg and K, and the possible oxidation products are Cl 2 and Br 2. Because Mg is more electronegative than K (χ = 1.31 versus 0.82), it is likely that Mg will be reduced rather than K. Because Cl is more electronegative than Br (3.16 versus 2.96), Cl 2 is a stronger oxidant than Br 2. the price is right july 14 2022
