Question

UL Jyll 2) When ammonium nitrite (NH4NO2) is heated, it decomposes to give nitro This property is used to inflate tennis balls. a) Write a balanced equation for the reaction. (2 points) b) What is the partial pressure of N2 if a sample of 25.0 g NH4NO2 was heated at 100 °C in a 10.0 L reaction vessel until all the NH4NO2 had decomposed? (3 points)

Answer 1

- a NHO NO 15) - 2 H₂O (9) + N219) by moles of NHU NO, Present = weight Molar mass - 25 – 0.39 64 I mole of NHINO gives 2 mol H₂O and t mole of a gas. 0.39 more of NHO NO will give. using PraMRT Partial Pressure Pr2 = MRT Prz = 0.39 0.0841 x 373 = Lelg am cy t mole of NHO NO give t mole of Na gas. moles of Na gas required n- P - 120 x 86.2 103 RT 0.0821 x 295 n = 0.00us. moles of NHA NO required = 0.0043 Weight of NHO NO = 0.0043 x64 {malar mass} wt on NHUNG 0.275 m
