A) 1, 2, 4, 4
B) 2, 4, 6, 7
C) 1, 2, 4, 6
D) 2, 4, 7, 6
Correct Answer: B
Solution :
: \[MnS{{O}_{4}}:+x-2=0\Rightarrow x=+2.\] \[Mn{{O}_{2}}:x+2(-2)\Rightarrow x-4=0\Rightarrow x=+4\] \[{{K}_{2}}Mn{{O}_{4}}:(+1)\times 2+x+(-2)\times 4\] \[\Rightarrow \]\[+2+x-8\Rightarrow x=+6.\]You need to login to perform this action.
