PAN (पेरोक्सीअसेटाइल नायट्रेट) खालील परस्पर क्रियेच्या परिणामी तयार होतो. PAN (Peroxyacetyl nitrate) is formed as a result of following interaction :
1)नायट्रोजन ऑक्साइड आणि सल्फर डायऑक्साइड / Nitrogen oxide and sulfer dioxide
2)कार्बन मोनोऑक्साइड आणि अस्थिर सेंद्रिय संयुगे / Carbon monoxide and volatile organic compounds✓ Correct
3)नायट्रोजन ऑक्साइड आणि हायड्रोकार्बन्स / Nitrogen Oxide and hydrocarbons
4)ओझोन आणि कण / Ozone and particulate matter
PAN (Peroxyacetyl nitrate) is a secondary pollutant formed in the atmosphere through photochemical reactions involving hydrocarbons (volatile organic compounds) and nitrogen oxides in the presence of sunlight.
जीवाश्म इंधन आणि पेट्रोलियमच्या ज्वलनातून __________ हे वायु मिळतात. Burning of fossil fuels and petroleum gives
a)(1) SO आणि NO
b)(2) SO2 आणि NO2✓ Correct
c)(3) S आणि N2
d)(4) NH3 आणि SO2
The burning of fossil fuels releases Sulfur dioxide (SO2) and Nitrogen dioxide (NO2), which are the primary precursors of acid rain.
