Question

REDOX REACTIONS
2KNO_3 --->2KNO_2 + O_2. Need help balancing using half-reaction method

Answer 1

Half-Reaction Method
1. Determine the half reaction base pairs
(usually other than H and O)
2. Balance the atoms other than H and O
3. Balance the O's with H2O's
4. Balance the H's with H+'s
5. Balance the charge with e-'s
STOP! When you get to this point this is where you stop and check to make sure that the e-'s are on the opposite sides of the arrow (reactants and products).
6. Multiply both equations now to get the e-'s to equal each other, then you will add the two half reaction equations together and they should cancel.

Answer 2

......

Answer 3

could you elaborate more on steps 1-4, im confused with balancing the h's and o's. and could you balance the equation i put so i can check my mistakes plz

Answer 4

what do i do about the coefficient of 2?

Answer 5

how does it affect the half reaction?
