A.NH4+ H = +4 N=-4 tpi krna ad muatan mines jd N=-3 B.H3PO4 = 0 ( 3 x Biloks H) + P+ ( 4 x Biloks O ) = 0 ( 3 x 1 ) + P + ( 4 x (-2) ) = 0 3 + S – 8 = 0 S = 8 – 3 S= +5 C. H2C2O4 H = +1 O = -2 jd C = +3 D. Ca(ClO3)2 Ca gol 2 kan = +2 Oksigen = -2 x 3= -6 x 2 = -12 jdi Cl= +10 tapi karna Cl 2 jdi Cl =+5
clay@ oke makasih :)
