Out of various oxides of N2 only three namely nitric oxide NO, nitrogen dioxide NO 2 and nitrous oxide N2O are present in the atmosphere in significant amounts. For example N2O5.On other hand phosphorus due to its larger size does not form this type of multiple bonds with oxygen but instead forms single bonds and forms oxides with cage like structure.For example P4O10. The following table gives the brief information of Why is an alkylamine more basic than ammonia? MEPC 58/23/Add.1 ANNEX 14 RESOLUTION MEPC.177(58) Adopted on 10 October 2008 AMENDMENTS TO THE TECHNICAL CODE ON CONTROL OF EMISSION OF NITROGEN OXIDES FROM MARINE DIESEL ENGINES (NO x Technical Code 2008) The lifetime of nitrogen oxides (NOx) affects the x A carbon monoxide and sulfur dioxide B oxides of nitrogen and sulfur dioxide The Chemistry NCERT Solutions Class 12 provides extensive step-by-step solutions to diffcult problmes and equations which prepare students to crack difficulty levels in easiest way.
