Detailed Solution

●        Gunpowder is a compound made of phosphorus and sulphur when combined with other components.
●        As the ingredients interact with one another, creating smoke and sound, more heat is produced.
●        Including a few extra ingredients causes those colours to burn into the crackers.
●        Consequently, the two non-metals employed in fireworks are sulphur and phosphorus.
