Combustion
It is an example of a simple chemical reaction. In a combustion reaction, oxygen reacts with another substance to produce carbon dioxide gas and water vapor.
Answer:
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.

Answer:
Adding H₂O(g) to the system.
Explanation:
- Le Châtelier's principle states that when there is an dynamic equilibrium, and this equilibrium is disturbed by an external factor, the equilibrium will be shifted in the direction that can cancel the effect of the external factor to reattain the equilibrium.
<u><em>1) Removing H₂O(g) from the system:</em></u>
- This will decrease the concentration of the reactants side, so the reaction will be shifted to the left side to suppress the removal of H₂O(g) from the system.
<u><em>2) Adding CH₃CHO(g) to the system :</em></u>
- This will increase the concentration of the products side, so the reaction will be shifted to the left side to suppress the adding CH₃CHO(g) to the system.
<u><em>3) Removing C₂H₂(g) from the system:</em></u>
- This will decrease the concentration of the reactants side, so the reaction will be shifted to the left side to suppress the removal of C₂H₂(g) from the system.
<u><em>4) Adding H₂O(g) to the system:</em></u>
- This will increase the concentration of the reactants side, so the reaction will be shifted to the right side to suppress the addition of H₂O(g) to the system.
- <u><em>So, it is the right choice.</em></u>
