Question

19 Question (1 point) See page 293 In some aquatic ecosystems, nitrate (NO3) is converted to nitrite (NO2), which then decomposes to nitrogen and water. As an example of this second reaction, consider the decomposition of ammonium nitrite: NH NO2 (aq) N2(8)+2H20() 3rd attempt See Periodic Table See Hint What would be the change in pressure in a sealed 10.0 L vessel due to the formation of N2 gas when the ammonium nitrite in 2.00 L of 1.40M NH4NO2 decomposes at 25.0°C? atm 4.11

Answer 1

Here is the Solution:

ind eut the. ehange in pre ssure to we need Sea) १ d 10.0 LVEssel at 25 Gifven dato NH NO2 2.00 L Volume Molar ity M ma 1. 4C M melarity NH4 NOr N) . Reaction equation NHANO2 (2) 2H200 accor di to reachon equaton, the molar rato of NHNO s 1:1 andl N2 4 mol N2 means, 1 mol NHy No, First, we wfe fond otut tha moles a N2 Moles Ni= A ol N 1 mol NHNO mols N= 2.@ moles Seend, we wil fend the vsng ideal where, p pressure v volume (f10 L) pressure NA pu nRT nRT n moles N2 (2.6 pd o08m/(296.15 das onstaut P T temper qture 10.0 6.854 atm P = There fore, the ehange in pressure wil be 6.854 atm - 1.000 atm 5.854 atm
