Tentukan biloks unsur S pada: 1. S 2. SO3 3. H2SO4 4. Na2SO4 5. NaHSO3

1. S=0
2.SO3 = (1 × biloks S)+(3 × biloks O)=0
= ( 1 × biloks S)+(3 × (-2) ) =0
= biloks S + (-6)=0
= biloks S= 6
3. H2SO4 = (2 × biloks H)+(1 × biloks S)+(4 × biloks O)=0
= (2 × (1))+(1 ×biloks S)+(4 ×(-2)=0
= 2 + biloks S + (-8)=0
= biloks S= 8+(-2)
= 6
4. Na2SO4= (2 × biloks NA)+(1 × biloks s)+(4 × biloks O)=0
= (2 × (1))+(1 × biloks S)+(4 × (-2))=0
=2 + biloks S+ (-8)=0
=biloks S= 8+ (-2)
= 6
5. NaHSO3= (1 × biloks Na)+(1 × biloks H)+(1 × biloks S)+(3 × biloks O)=0
= (1 × 1)+(1 × 1)+(1 × biloks S)+(3 × (-2))=0
=1 + 1 + biloks S + (-6)=0
=biloks S = 6 + (-1 )+ (-1)
= 4
