write the composition of any one cracker that you will burn on Diwali
Answers
Firecrakers works on the principle of chemistry between compounds.
Composition of skyrocket
1. Oxidiser - potassium nitrate
2. Fuel - Black power propellant
3. Color - chemical like BaCO3 for green color.
The common crackers that we burn on Diwali have almost the same compositions, including charcoal and chemicals, like nitrates, chorates, perchlorates and sulphur.
Charcoal acts as fuel for combustion; while the nitrates, chlorates and perchlorates act as the oxidizing agents that provide the oxygen needed for burning crackers.
Sulphur and charcoal act as reducing agents that produce the required heat by burning oxygen.
Some safe metals are added for regulating the speed of all chemical reactions.
Also, the colouring agents are added for making colourful fires on burning those crackers.
