Question: Which of the following reaction is used to make a fuel cell [AIIMS 2003]
Options:
A) $ Cd(s)+2Ni{{(OH)}_3}(s)\to CdO(s)+2Ni(OH)+H_2O(l) $
B) $ Pb(s)+PbO_2(s)+2H_2SO_4(aq)\to 2PbSO_4(s)+2H_2O(l) $
C) $ 2H_2(g)+O_2(g)\to 2H_2O(l) $
D) $ 2Fe(s)+O_2(g)+4{H^{+}}(aq)\to 2F{e^{2+}}(aq)+2H_2O(l) $
Show Answer
Answer:
Correct Answer: C
Solution:
Overall reaction - $ 2{H_{2(g)}}+{O_{2(g)}}\to 2H_2O(l) $ .
