Options

A. `2KClO_(3) to2KCl+3O_(2)`
B. `2Fe(OH)_(3)+4H_(2)SO_(4)toFe_(2)(SO_(4))_(3)+6H_(2)O`
C. `2Pb(NO_(3))_(2)to2PbO+4NO_(2)+O_(2)`
D. `2KNO_(3)+FeSO_(4)toFeSO_(4)toK_(2)SO_(4)+Fe(NO_(3))_(2)`

Answer

2

Explanation

Second reaction is wrongly balanced . Correct balancing is as follows.
`2Fe(OH)_(3)+3H_(2)SO_(4)toFe_(2)(SO_(4))_(3)+6H_(2)O`
