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. cinnamon rolls dairy free gluten free

"Web25 de jan. de 2024 · Some moderately reactive metal oxides are reduced by using carbon as a reducing agent.
