Answer»

Justify that the following reactions are redox reactions:
$C u O (s) + H_{2} (g) \to C u (s) + H_{2} O (g)$

$F e_{2} O_{3} (s) + 3 C O (g) \to 2 F e (s) + 3 C O_{2} (g)$

$4 B C l_{3} (g) + 3 L i A l H_{4} (s) \to 2 B_{2} H_{6} (g) + 3 L i C l (s) + 3 A l C l_{3} (s)$

$2 K (s) + F_{2} (g) \to 2 K + F - (s)$

$4 N H_{3} (g) + 5 O_{2} (g) \to 4 N O (g) + 6 H_{2} O (g)$
