Vedclass · Answer

(D) Hydrogen $(H_2)$ acts as a reducing agent for metal oxides of metals that are less reactive than hydrogen in the reactivity series. $Al$ is more reactive than $H_2$,so $Al_2O_3$ cannot be reduced by $H_2$. $CuO$,$Fe_2O_3$,and $SnO_2$ are oxides of metals less reactive than hydrogen and can be reduced by $H_2$.

Which of the following will not be reduced by $H_2$?
