Question

Which of the following reduction reaction CANNOT be carried out with coke? (A) Al 2 O 3 arrow Al (B) ZnO arrow Zn (C) Fe 2 O 3 arrow Fe (D) Cu 2 O arrow Cu

Tardigrade Admin · Accepted Answer

Reduction of Al 2 O 3 arrow Al is carried out by electrolytic reduction of its fused salts. ZnO , Fe 2 O 3 Cu 2 O can be reduce by carbon.

Q. Which of the following reduction reaction CANNOT be carried out with coke?

$A l_{2} O_{3} \to A l$

$Z n O \to Z n$

$F e_{2} O_{3} \to F e$

$C u_{2} O \to C u$

Reduction of $A l_{2} O_{3} \to A l$ is carried out by electrolytic reduction of its fused salts. $Z n O, F e_{2} O_{3} & C u_{2} O$ can be reduce by carbon.

Q. Which of the following reduction reaction CANNOT be carried out with coke?

Al2​O3​→Al

ZnO→Zn

Fe2​O3​→Fe

Cu2​O→Cu

Reduction of Al2​O3​→Al is carried out by electrolytic reduction of its fused salts. ZnO,Fe2​O3​&Cu2​O can be reduce by carbon.

$A l_{2} O_{3} \to A l$

$Z n O \to Z n$

$F e_{2} O_{3} \to F e$

$C u_{2} O \to C u$

Reduction of $A l_{2} O_{3} \to A l$ is carried out by electrolytic reduction of its fused salts. $Z n O, F e_{2} O_{3} & C u_{2} O$ can be reduce by carbon.
