<span>An exothermic reaction that is accompanied by a decrease in entropy would be classified as a spontaneous reaction. A spontaneous reaction is a reaction that favors the formation of products under the conditions in which the reaction is occurring.</span>

In order to compute this, we must first take a couple of assumptions of:
1) The laboratory size so we can calculate its volume
2) The number of students working in the lab so we know the total gas produced
Let the lab be
11 m × 9 m × 6 m
The volume then computes to be:
594 m³
We know that
1 Liter is 1 dm³
1 m = 10 dm
1 m³ = 1000 dm³
Therefore, the room volume in liters is:
594,000 Liters
Let there be 30 students in the laboratory
Total gas being produced:
6 × 30
= 180 Liters
This works out to be:
0.03% of Hydrogen by volume
Therefore, there is no risk of explosion given our assumption of size and students.
Answer: %C = 63.5%, %H = 6.00%, %N = 9.3%, %O = 21.2%
