Click in the answer box to activate the palette. use the half-reaction method to balance the following equation in acidic solution. it is not necessary to include any phases of matter for any species. cn− + mno4− → cno− + mno2

The balanced reaction in the acidic medium is:

Explanation:

1) ( oxidation)

Balance oxygen by adding water :

Now , balance hydrogen by adding hydrogen ions on the side where hydrogen are less.

Add electrons to balance charge where positive charge is more.

..[1]

2) (reduction)

Balance oxygen by adding water :

Now , balance hydrogen by adding hydrogen ions by adding them on the side where hydrogen are less.

..[2]

Add electrons to balance charge where positive charge is more.

..[2]

3 × [1] + 2 × [2]

The balanced reaction in the acidic medium is:

the answer is the first option

explanation:

just googled it m8. not that hard

lol

can you attach the
