In some ﬁreworks there is a reaction between powdered aluminium and powdered barium nitrate in which heat is evolved and an unreactive gas is produced.

What is the equation for this reaction?

A. 2Al + Ba (NO3) 2 - > Al2O3 + BaO + 2NO

B. 4Al + 4Ba (NO3) 2 - > 2Al2O3 + 4 Ba (NO2) 2 + O2

C. 10Al + 3 Ba (NO3) 2 - > 5Al2O3 + 3BaO + 3N2

D. 10Al + 18Ba (NO3) 2 - > 10Al (NO3) 3 + 18BaO + 3N2

I think the correct answer from the choices listed above is option A. The correct equation would be:

2Al + 3Ba (NO3) 2 - > Al2O3 + 3BaO + 6NO2

The products would be aluminum nitrate, barium oxide and nitrogen dioxide.
