Question

why is chlorine +5? It's not a balanced equation if it is 5 because the sum of the whole thing equals +4 when isn't the whole point to make it b balanced to 0

Answer 1

Step-by-step explanation:

KClO₃ ⇒ KCl+ O₂

Oxidation state for each oxygen in O₃ = -2. There are 3 oxygens so the total is -6 (3 x -2 = -6) .

Oxidation state for K = +1.

Solve the oxidation state for chlorine. Treat chlorine as an unknown and solve for its oxidation state using the two known oxidation values for K and O.

+1 - 6 + chlorine = 0

-5 + chlorine = 0

+5 - 5 + chlorine = 0 + 5

chlorine = +5
