RAEHANJalaskan biloks masing-masing unsur dalam senyawa atau ion berikut: a. NH4NO3 -----> NH4 - + NO3- NH4 - = -1 N + 4 = -1 N = -5 NO3 - = -1 N + -6 = -1 N = +5
b.CR2O7-2 Cr + -14 = -2 Cr = +12 c.Na2CO3 2 + C + -6 =0 C = 4

A. N -= +5, H = -1, O = -2 b. O = -2, Cr = +6 c. Na = +1, C = +4, O = -2
a. NH4NO3 -----> NH4 - + NO3-
NH4 - = -1
N + 4 = -1
N = -5
NO3 - = -1
N + -6 = -1
N = +5
b.CR2O7-2
Cr + -14 = -2
Cr = +12
c.Na2CO3
2 + C + -6 =0
C = 4
b. O = -2, Cr = +6
c. Na = +1, C = +4, O = -2
