H₂O₂+KMnO₄+HNO₃ -------->Mn(NO₃)₂+KNO₃+H₂O+O₂

 

K= 1................................................K = 1

Mn=1.............................................Mn = 1

N = 1..............................................N = 3

H=3.................................................H = 2

O = 9..............................................O =12

 

H₂O₂+KMnO₄+ 3HNO₃ -------->Mn(NO₃)₂+KNO₃+ 3H₂O+O₂

 

espero que te sirva, salu2!!!!
