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: NH4NO2(aq) = N2(q)+2H2O(l)
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 1.40 L of 0.900 M NH4NO2 decomposes at 25.0°C? answer in atm

"NH_4NO_2 \\rightarrow N_2 + 2H_2O"
Find moles of NH4NO2
"n=c\\times V= 0.900\\times 1.40 = 1.26 mol"
Accordring to equation "n(N_2) = n(NH_4NO_3) = 1.26 mol"
