318395 Some statements regarding air pollution are given. Among them, the correct statements are
(I) Above \(80 \%\) of \(\mathrm{CO}\) is released from automobiles.
(II) In urban areas, at the peak time of the traffic the level of \(\mathrm{CO}\) is 100 to \({\text{550}}\,\,{\text{ppm}}\)
(III) If the percentage of \(\mathrm{CO}-\mathrm{Hb}\) in the blood is \(32 \%\), it causes immediate death
(IV) TLV of CO in the atmosphere is 9ppm

318397 Consider the following statements regarding compounds which cause global warming. ' \(\mathrm{X}\) ' is a hydrocarbon, \(\mathrm{A}\) and \(\mathrm{B}\) are neutral oxides of nitrogen, ' \(\mathrm{C}\) ' is a blue coloured gas and ' \(\mathrm{D}\) ' is released when \(\mathrm{H}_{2} \mathrm{~S}\) is reacted with oxygen. Identify the correct statements about X, A, B, \(\mathrm{C}\) and \(\mathrm{D}\).
(I) ' \(\mathrm{X}\) ' is mainly present in natural gas
(II) In A & B, one is diamagnetic and another one is paramagnetic
(III) ' \(\mathrm{C}\) ' can be identified by using liquid element in d-block
(IV) 'D' causes acid rain.
