Question

When solid nitrogen triiodide is heated, a mixture of nitrogen gas and solid iodine is produced. Write a balanced chemical equation for this reaction.

Answer 1

Nitrogen tri iodide - NI₃

Nitrogen - N₂

Iodine - I₂

Given when Nitrogen tri iodide is heated we get nitrogen gas and solid iodine.

NI₃ ----------> N₂ + I₂

Balance N atoms:

2NI₃ -------> N₂ + I₂

Now balance I:

2NI₃ -------> N₂ + 3I₂

Therefore the balanced chemical reaction for the reaction is:

2NI₃ -------> N₂ + 3I₂
