Which ion is not an oxyanion? no− so4 2− cn− co3 2−

CN⁻

Explanation:

Oxyanion:

Oxyanion is the anion that have oxygen atom.

General formula:

The general formula for oxyanion is AₓOₓ⁻².

A = symbol of element combining with oxygen.

O = oxygen atom

z,x, = integers

a) =  NO⁻

Its is an oxyanion because oxygen atom is present with nitrogen.

b) = SO₄⁻

It is an oxyanion because oxygen atom is present.

c) = CN⁻

This is not an oxyanion because there is no oxygen atom present.

d= CO₃²⁻

It is also an oxyanion because of presence of oxygen atom.

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
