balance it

​

Answer 1

Answer:

step 1 - balance elements other than hydrogen and oxygen. indicate substance oxidised and reduced.

step 2 - find total increase and total decrease in O.N. per atom n make then equal by multiplying suitable factor

step 3 - balance oxygen by adding water

molecules on side where oxygen are less

balance hydrogen by adding H+ on side where hydrogens are less

Check the equation
