The decomposition of nitroglycerin is a very rapid and exothermic reaction, producing a large volume of gases. The primary gases produced are:

* Nitrogen (N₂)

* Carbon dioxide (CO₂)

* Water vapor (H₂O)

* Oxygen (O₂)

The exact proportions of these gases vary slightly depending on the conditions of the explosion. However, this reaction is extremely dangerous and should only be carried out by trained professionals in a controlled environment.

Here is the unbalanced chemical equation for the decomposition of nitroglycerin:

C₃H₅N₃O₉ (l) → N₂ (g) + CO₂ (g) + H₂O (g) + O₂ (g)

It is important to note that the decomposition of nitroglycerin is a complex process and can also produce small amounts of other gases and byproducts, like:

* Carbon monoxide (CO)

* Nitrogen oxides (NOx)

* Nitric acid (HNO₃)

These byproducts can be highly toxic and contribute to the explosive nature of nitroglycerin.
