When sodium azide is activated in an automobile airbag, nitrogen gas and sodium are produced according to the equation
2 NaN3(s) −→ 2 Na(s) + 3 N2(g).
If 0.56 mol of NaN3 reacts, what mass of
nitrogen would result?
Answer in units of g

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na

#2- the hno3 has a h+ ion and the naoh has an oh- ion
