In older airbags, sodium azide, NaN3, was used as a source of nitrogen gas to rapidly inflate the airbag. This practice was mostly discontinued due to the high toxicity of sodium azide. The reaction of interest is 2 NaN3 (s) → 2 Na (s) + 3 N2 (g)
How many grams of N2 are produced if a 35.0 g charge of NaN3 decomposes?
Considering the same prompt, suppose I wanted to inflate a 125 L airbag with N2 (g) to a density of 0.450 g N2 / L. This is more or less a typical value for the passenger airbag. To do so I would need Answer g of N2 (g).
Considering the reaction for the decomposition of sodium azide, this would require a Answer g of NaN3.
This same process would produce Answer g Na (s). Keep in mind that sodium metal is highly reactive, and that a dose of ~ 2 g of sodium azide can be lethal. Sodium azide is still used in some airbags, but it has largely been phased out due to the legitimate safety concerns.

Question text
An aeroplane flies at a ground velocity (i.e. velocity relative to
the ground) of 300 km/h N 30o W, in a wind blowing at a velocity
of 50 km/h N 20o E. What is the velocity (speed and direction)
of the plane relative to the ground? (Use a calculator and round the speed
to the nearest km/h, and the corresponding angle to the nearest degree.)
Consider the decomposition of
6x3+x−3/x2−2x+1
into partial fractions
