Question

Me ajudem por favor!

Answer 1

1) Cl2O5
2Cl + 5 (-2) = 0
2 Cl - 10 = 0
Cl = 10/2
Cl = +5

B) HCl
+ 1 + Cl = 0
Cl = -1

C) HClO2
+ 1 + Cl + 2 (-1) = 0
Cl = 2 - 1
Cl = +1

D) Cl2
Cl = 0

2) NaNO2
+1 + N + 2 (-2) = 0
N = 4 - 1
N = +3

H2PO3
2 x 1 + P + 3 (-2) = 0
2 + P - 6 = 0
P = +4

Ba2 As2O7
2 x 2 + 2 As + 7 (-2) = 0
4 + 2As - 14 = 0
As = 5

3) A) Base fraca, monobase, solúvel
B) Base forte, dibase, pouco solúvel
C) Base fraca, tribase, insolúvel.
