1. H: +1 As: +5 O:-2
2. H: +1 Mn: +4 O:-2
3. H: +1 Cr: +6 O:-2
4. H: +1 W: +6 O:-2
5. H: +1 Cl: +5 O:-2
6. Cl2 = +3 O = -2
7. H: +1 Cl = -1
8. Na: +1 Cl: +7 O: -2
Explicación:
1.
₊₁ ₊ₓ ₋₂
H₃AsO₄
+3 +x -8 = 0
x = +8 -3
x = +5
H: +1 As: +5 O:-2
2.
₊₁ ₊ₓ ₋₂
H₂MnO₃
+2 +x - 6 = 0
x = +6 - 2
x = +4
H: +1 Mn: +4 O:-2
3.
₊₁ ₊ₓ ₋₂
H₂Cr₂O₇
+2 +2x - 14 = 0
2x = +14 - 2
x = +12 /2
x = +6
H: +1 Cr: +6 O:-2
4.
₊₁ ₊ₓ ₋₂
H₂WO₄
+2 +x - 8 = 0
x = +8 - 2
x = +8 /2
x = +6
H: +1 W: +6 O:-2
5.
₊₁ ₊ₓ ₋₂
HClO3
+1+x-6 = 0
x = +6 - 1
x = +5
H: +1 Cl: +5 O:-2
6.
₊ₓ ₋₂
Cl2O3
+2x -6 = 0
x = +6 /2
x = +3
Cl2 = +3 O = -2
7.
₊₁ ₋₁ = 0
HCl
H: +1 Cl = -1
8.
₊₁ ₊ₓ ₋₂
NaClO₄
+1 +x-8 = 0
x = +8 -1
x = +7
Na: +1 Cl: +7 O: -2
