What is the formula for hexaboron nitride?

-BN
-BN6
-B6N
-BN2

Explanation:

1. Boron nitride is prepared synthetically in lab.

2. When ammonia is treated  with boric acid or boron trioxide boron nitride is prepared.This are the other reaction to produce boron nitride.

Properties of Boron nitride :  

1. Boron nitride is  ionic in nature hence it reduces he co valency and electrical conductivity.

2. Hexa-boron nitride is thermally stable.1. Boron nitride is prepared synthetically in lab.

alienation, transformation, consumption, and the relativity of truth.

you can choose any one of these, they are all important themes.

these themes reflect the distinct sensibilities of both the modernist and postmodern aesthetic movements. (from google, you should paraphrase)

hope this !
