GEOLOGY

Detailed explanation-1: -Fireworks are the result of chemical reactions involving a few key components–like a fuel source (often charcoal-based black powder), an oxidizer (compounds like nitrates, chlorates that produce oxygen) and a color-producing chemical mixture. The oxidizer breaks down the chemical bonds in the fuel, releasing energy.

Detailed explanation-2: -The explosion of fireworks is an exothermic redox reaction. The fuel oxidizes (burns) quickly, causing a great buildup in pressure that eventually leads to solids and gases bursting across the sky in colorful patterns.

Detailed explanation-3: -What can you tell us about the chemical reactions that go into a fireworks display? Traditionally, three reagents, potassium nitrate, carbon, and sulfur, make gunpowder. You’re doing a combustion reaction out of those types of materials that creates this detonation explosion.

Detailed explanation-4: -Metal salts commonly used in firework displays include calcium chloride, sodium nitrate, barium chloride, copper chloride, etc. The green flame produced in fire-works is due to the presence of Barium. The blue flame is due to the presence of Copper.

Detailed explanation-5: -In order to accomplish that, metal salts are mixed with chemicals (oxidizing agents) that cause a very rapid oxidation reaction to occur. This reaction is very fast and exothermic, which means it gives off energy as heat-and anytime you have a very fast and hot reaction, you get an explosion.
