In some aquatic ecosystems, nitrate $\left({\mathrm{NO}}_3^{?}\right)$is converted to nitrite $\left({\mathrm{NO}}_2^{?}\right)$, which then decomposes to nitrogen and water. As an example of this second reaction, consider the decomposition of ammonium nitrite: ${\mathrm{NH}}_4{\mathrm{NO}}_2(aq)?{\mathrm{N}}_2(g)+2{\mathrm{H}}_2\mathrm{O}(l)$ 2nd attempt What would be the change in pressure in a sealed $10.0\mathrm{L}$ vessel due to the formation of ${\mathrm{N}}_2$ gas when the ammonium nitrite in $2.80\mathrm{L}$ of $0.900\mathrm{M}{\mathrm{NH}}_4{\mathrm{NO}}_2$ decomposes at $25.0^{?}\mathrm{C}?$ atm
