Question

Tentukan biloks ari
a.N2H4
b.S2O3^-2

Answer 1

A. N2H4
N2H4=0
biloks N2 + biloks H4=0
biloks N2 + 4*1=0
biloks N2+4=0
biloks N2=4
biloks N=2

b. biloks S2 + biloks O3=-2
biloks S2 + 3*-2=-2
biloks S2-6=-2
boloks S2=-2+6
biloks S2=4
biloks S=2.


lw gak salh ya.

Answer 2

N2H4
H= +1
H4= +4
N2= -4
N= -2

S2O3^-2
O= -2
O3= -6
S2 - 6 = -2
S2 = +4
S = +2
