Question

calcule o nox
a)H³O+
b)AgNO3
c)ZnS
d)CO2
h)Zn
​

Answer 1

b)

$AgNO_{3}=+1+x+3.(-2)=0\\1+x-6=0\rightarrow\,x=6-1=5$

$\boxed{\boxed{\mathsf{Nox_{N}=+5}}}$

c)

$ZnS=2+x=0\rightarrow\,x=-2$

$\boxed{\boxed{\mathsf{Nox_{S}=-2}}}$

d)

$CO_{2}=x+2.(-2)=0\\x-4=0\rightarrow\,x=4$

$\boxed{\boxed{\mathsf{Nox_{C}=+4}}}$

e)

$\boxed{\boxed{\mathsf{Nox_{Zn}=+2}}}$
