Pada O2 = 0
        O3 = 0
        H2O = -2
        F2O = -2
        F2O2 = -1
carnya gimna kaka...
aku ga ngrtii.. pelis aku bingung bagett

- O2 = O3 = 0 -> krn tdak memiliki muatan.
- H2O = 2 H + O = 0
2 (1) + (-2) = 0 -> 2-2 = 0
- F2O = 2 F + O = 0 -> 2 (0) + (-2) = 0 -> 2f-2=0 F=2/2 =1
- O2F2 = 2 O + 2 F = 0 -> 2(-2) + 2F = 0 -> -4 + 2f =0 F= 4/2 =2
- Na2O2 = 2Na + 2 O=0 -> 2(1) + 2 (-2) = 0 -> 2-4 = -2
- KO2 = K + 2 O = 0 -> 1+2(-2) = 0 -> 3
- H2SO4 = 2 H + SO4 = 0 .
semoga membantu, maaf klo ada yg salah
