Airbags are present in all new cars being produced today. When a collision occurs, a sensor sends an electric signal to a canister containing sodium azide (NaNs). This generates heat, which starts the chemical reaction that produces nitrogen gas, which inflates the airbr chemical reaction is:

Question

2NaNg(s) -+ 2Na(s) + 3N2(g)
How many moles of nitrogen gas are produced if 1.25 mol of NaNs are reacted?

Answer 1

From the balanced chemical equation, we can see that 2 moles of NaNs produce 3 moles of N2 gas.

Therefore, if 1.25 mol of NaNs are reacted, we can use the ratio from the balanced equation:

1.25 mol NaNs * (3 mol N2 / 2 mol NaNs) = 1.875 mol N2

Therefore, 1.25 mol of NaNs would produce 1.875 mol of N2 gas.
