Asked by maham237 @ in Chemistry viewed by 925 People
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
