QUESTION 7 (Start on a new page.) The airbags in motor vehicles contain the compound sodium azide (NaNs). When a car crashes into an object, the compound decomposes and the nitrogen inflates the airbag. The balanced equation for the reaction is as follows: NaN(s) → 2Na(s) + 3N2(g) In one such decomposition, 2,53 x 10° molecules of nitrogen are generated. Calculate the: 7.1 Number of moles of NaN(s) that decomposed 7.2 Volume of N2(g) produced Assume that the reaction occurs at standard pressure. QUESTION 8 (Start on a new page.) Aluminium sulphate is used as a coagulant in water purification. It reacts with sodium hydroxide to form aluminium hydroxide which drags the impurities as it settles. The balanced equation for the reaction is: Al2(SO4)3(aq) + 6NaOH(aq) → 2Al(OH)3(s) + 3Na2SO4(aq) A chemist at a water purification plant adds 700 g of Al2(SO4)3 to a sample of water. 8.1 Calculate the maximum mass of Al(OH)3 that can be produced from this mass of Al2(SO4)3.
