Q4. Some airbags in cars contain sodium azide (NaN3). (a) Sodium azide is made by reacting dinitrogen monoxide gas with sodium amide (NANH2) as shown by the equation. 2NANH2 + N20 → NaN3 + NAOH NH3 Calculate the mass of sodium amide needed to obtain 550 g of sodium azide, assuming there is a 95.0% yield of sodium azide. Page 5 of 12 Give your answer to 3 significant figures. (b) If a car is involved in a serious collision, the sodium azide decomposes to form sodium and nitrogen as shown in the equation. 2NAN3(s) 2Na(s) + 3N2(g) The nitrogen produced then inflates the airbag to a volume of 7.50 x 10-2 m3 at a pressure of 150 kPa and temperature of 35 °C. Calculate the minimum mass of sodium azide that must decompose. (The gas constant R = 8.31 J K-1 mol-1) (Hint: find out the number of moles of Nzusing Ideal gas equation, and determine the number of moles and mass of NaN3 from the balanced equation)

An old antacid commercial claimed that each tablet of their product could neutralize 47 times its mass in stomach acid. The active ingredient in the antacid tablet, NaAl(OH)₂CO3, reacts with the HCI in stomach acid according to the balanced reaction here. NaAl(OH)₂CO3 + 4HCI → NaCl + AlCl3 + 3 H₂O + CO₂ How many moles of HCI can a 1.48 g antacid tablet neutralize if the tablet contains 0.354 g of the active ingredient? number of moles of HC1 = mol If stomach acid has a concentration of 0.14 M HCl, determine how many times the tablet's own mass of stomach acid can be neutralized by the 1.48 g antacid tablet. Assume that stomach acid has the density of water, 1.00 g/mL. number of times =
