Question
The mixture of hydrogen and oxygen is called:
- Hydrating mixture
- Explosives
- Detonating mixture
- Homogeneous mixture
Hint:
fuel spray in air is one of the example.
The correct answer is: Detonating mixture
The mixture of hydrogen and oxygen is called detonating mixtures.
Detonations can occur not only in homogeneous gaseous, liquid, or solid explosives, but also in heterogeneous mixtures such as fuel sprays in air.
