Answer 1

brarium is my answer hope this will help you

Answer 2

Firecrackers are generally made of cardboard or plastic, with flash powder, cordite, smokeless powder, or black powder as the propellant. This is not always the case, however. Anything from match heads, kerosene to lighter fluid have been used successfully in making firecrackers. The key to loud firecrackers, however, although in part lying in the propellant substance, is pressure. The entire firecracker must be very tightly packed in order for it to work best. Flash powder, however, does not need to be packed tightly, and should not be.

So chemicals are-
The various chemicals in fireworks and their effects -

Sulfur dioxide: Causes wheezing and shortness of breath.

Cadmium: Can cause anemia and damage to kidney and also affect the nervous system.

Copper: Irritates respiratory tract

Lead: Affects the nervous system

Magnesium: Can cause metal fume fever

Nitrate: Can cause mental impairment

Nitrite: Can cause skin problems, eye irritation, and respiratory problems in children.
