Question: In the redox reaction $ xMnO+yPbO_2+ $ $ zHNO_3\to HMnO_4+Pb{{(NO_3)}_2}+H_2O $
Options:
A) $ x=2,y=5,z=10 $
B) $ x=2,y=7,z=8 $ b
C) $ x=2,y=5,z=8 $
D) $ x=2,y=5,z=5 $
Show Answer
Answer:
Correct Answer: A
Solution:
[a] The balance equation is $ \underset{\overset{\uparrow }{\mathop{x}},}{\mathop{2MnO}},+\underset{\overset{\uparrow }{\mathop{y}},}{\mathop{5PbO_2}},+10H\underset{\overset{\uparrow }{\mathop{z}},}{\mathop{NO_3}},\to 2HMnO_4+5pb{{(NO_3)}_2}+4H_2O $
