Interpretation:
The substances used to produce colors in fireworks, needs to be identified.
Concept introduction:
Electrons absorb energy and become excited. Due to this phenomenon, a chemical gets its color. That excitation absorbs

Answer to Problem 3E
Carbon, aluminum, phosphorous, Sulphur, etc.
Explanation of Solution
Metal salts generally used in firework shows, consist of: calcium chloride (orange fireworks), strontium carbonate (red fireworks), sodium nitrate (yellow fireworks), copper chloride (blue fireworks) and
barium chloride (green fireworks).
Carbon is the prime components of black powder which is used in fireworks. Silver and white color produced by aluminum, it also gives sparks and flames in the fireworks. Spontaneousignition in the air is due to the presence of phosphorous and Sulfur helps to fuel fireworks.
