How many moles of potassium chlorate need to be heated to produce 18.2 litres of oxygen at NTP?

Options

A. 0.24
B. 0.48
C. 22.4
D. 4.8

Answer

A

Explanation

(A)`[V(CO)_6]-d^2sp^3` containing one unpaired electron `(d^5)`
`K_4[Mn(CN)_6]-d^2sp^3` containing one unpaired electron `(d^5)`
`[CuF_6]^(2-)`-It is a low spin octahedral complex with one unpaired electron `(d^7)`
(B)`[NiCl_4]^(2-) and [NiCl_2(PPh_3)_2]-sp^3` containing two unpaired electrons `(d^8)`
`[NiCl(PPh_3)_3]-sp^3` containing one unpaired electron `(d^9)`
(C )`[CuF_4]^(-)`-diamagnetic planar complex with `d^9` configuration .
`[Cu(CN)_4]^(3-)`-diamagnetic tetrahedral complex with `d^10` configuration.
(D)`[Fe(CN)_6]^(4-)`-diamagnetic with +2 oxidation state of iron.
`[Fe(H_2O)_5NO^(+)]` -paramagnetic with +1 oxidation state of iron.
`[Fe(CN)_5NO^(+)]^(2-)`-diamagnetic with +2 oxidation state of iron.
