1. A mixture of H2 and Ne is placed in a 2.00 L flask at 25.0 oC. The partial pressure of H2 is 1.6 atm and of Ne is 2.8 atm. What is the mole fraction of Ne?

2. Sodium azide (NaN3, 65.01 g/mol) decomposes to yield sodium metal and nitrogen gas according to the unbalanced equation below. If 1.32 g NaN3 decomposes at 173 oC and 752 torr, what volume of gas will be produced?

NaN3(s) → Na(s) + N2(g)

A vehicle airbag uses a gas generator that contains a mixture of three compounds: NaN3NaN3 , KNO3KNO3 , and SiO2SiO2 . A series of three reactions is used to convert the highly toxic sodium azide, NaN3NaN3 , into N2N2 gas and harmless silicate glass. The nitrogen gas fills up the airbag, causing it to rapidly expand in a head‑on collision. Balance the reactions involved in the deployment of an airbag by inserting the appropriate coefficients. reaction 1: NaN3(s)−→ΔNa(s)+N2(g)NaN3(s)→ΔNa(s)+N2(g) reaction 2:...
