The impact of a collision triggers the de NaNo(s) - Na(s) +3N2(e). If airbag is an approximate cube with its side length equals to temperature (25.0°C) and pressure of 800 mmlig, how many of NaN; is required to deploy the of a collision triggers the decomposition of NaN, as follows - de length equals to 35.0cm, and if the airbag is operated at ambient ?

Answer 1

Solution 2 Na Nis) 2. Na (57 + 3N (9) 13) (35 un) 2) 428.75 m² Volume of air bag = 42.875 litred Temprature = 25°(2) 298K I pressure - 800 mm Hg = 800 760 1.05 at an Applying ideal gas equation, PV2nRT Putting the values, 105x 42.8753 nx 0.0821 x 298 o na 45:018 of 1.84 moles. 24.46

Now, 3 moles of N = 2moles of NaN | 1-84 moles of N = 2 x 1.84 1 1.22 moles of Na No Amount în grams a) 1.22 x 659. moll Answers) 79.3 g of NaNg to be decomposed.
