Answer:

HEYA ARMY

Explanation: HOPE IT HELPS UH!

In the case of aluminum nitride, the crisscross method would yield a formula of Al3N3, which is not correct. A second step must be performed in which the subscripts are reduced but the ratio is kept the same. Al3N3 can be reduced to AlN because both formulas describe a 1:1 ratio of aluminum ions to nitride ions.
