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
