Answer:
this is very easy to solve
- (NH4)2 Co3,(NH4)2 So4,( NH4)3 Po4
- k2 co3, k2 so4,k3 Po4
- zn oh2, zn (No3)2, zn3 (Po4)
- ca oh2
- fe oh3, fe(No3)3, fe2 (co3)3, fe2 (so4)3
this is a answer I am very sure
<span> Au</span>₂(SeO₄)₃
O = -2 × 4 = -8
Se = + 6
So,
(+6 - 8) = -2
Means (SeO₄) contains -2 charge, Now multiply -2 by 3
-2 ₓ 3 = -6
Means,
Au₂ + (-6) = 0
Au₂ = +6
Or,
Au = 6 / 2
Au = +3
Result:
Au = +3
Se = +6
O = -2
Ni(CN)₂
Cyanide (CN⁻) contains -1 charge,
So,
N = -3
C = +2
Then,
Ni + (-1)₂ = 0
Ni - 2 = 0
Or,
Ni = +2
Result:
N = -3
C = +2
Ni = +2
