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)

Question 25 of 97 Submit DDT was an insecticide used to prevent mosquito borne diseases. Due to the harmful effects on birds and fish, it is now banned in the US. However, other countries still use it to control mosquitos. It can be prepared by the reaction shown below. Determine the amount of DDT that can be produced and the percent yield for this reaction. 2C6H,CI + C2HOCI, – C,4H9CI, + H20 2 3 NEXT If a company in South America started with 1175 g of chlorobenzene (C6H5CI, MW 112.55 g/mol) and 538.5 g of chloral (C2HOCI3, MW 147.39 g/mol), set up the table below that represents 100% yield with the given reaction conditions. 2C6H,CI C2HOCI, C1.H,Cls H2O Before (mol) Change (mol) After (mol) O RESET 3.132 -3.132 3.654 -3.654 7.308 0. + -7.308 10.44 -10.44 MacBook Air F12 II F8 F10 F11 000 F9 20 F3 F7 F4 F5 F6 esc F2 F1 +.

ABS plastic is a polymer consisting of three monomer units: acrylonitrile (C₃H₃N), butadiene (C₄H₆), and styrene (C₈H₈). A sample of ABS plastic contains 11.9% N by mass. It took 1.56 g of Br₂ to react completely with a 2.00 g sample of ABS plastic. Bromine reacts 1:1 (by moles) with the butadiene units in the polymer and nothing else, so bromination is a method for determining the quantity of butadiene in the polymer. What is the percent by mass of styrene in the polymer?
