The distinctive colors seen in many fireworks displays are primarily produced by burning what type of chemical compounds?

APure oxygen gas
BOrdinary table salt only
CLiquid nitrogen
DVarious metal salts

Explanation

The vivid, distinctive colors seen in fireworks displays are primarily produced by burning various metal salts, with each specific metal compound producing a characteristic color when heated to high temperatures, such as strontium salts commonly producing red, copper salts producing green or blue, and sodium salts producing a bright yellow-orange. Firework manufacturers carefully select and combine specific metal compounds to achieve the wide range of colors and effects seen in a typical elaborate fireworks display. This same fundamental chemical principle, in which different metals produce distinctive flame colors when heated, is also used in some basic chemistry classroom demonstrations.
