Question

1. sep construct an explanation a fireworks designer is planning a red-, white-, and blue - themed finale for her fireworks display. she is also planning a fountain effect. describe the chemicals she will need and how each will produce the desired effect.

Explanation:

For red color, strontium salts can be used as they emit red - orange light when heated due to electron transitions. For white color, magnesium or aluminum powders burn brightly to produce white light. For blue color, copper compounds like copper chloride can be used as they emit blue light when the electrons in the copper atoms are excited. For the fountain effect, a mixture of a fuel (such as charcoal) and an oxidizer (like potassium nitrate) can be used in a tube - like structure. The reaction between the fuel and oxidizer produces gases that push the burning material out in a fountain - like manner.

Answer:

For red: strontium salts (emits red - orange light from electron transitions). For white: magnesium or aluminum powders (burn brightly to give white light). For blue: copper compounds (emit blue light from excited electrons). For fountain effect: a fuel - oxidizer mixture (produces gases to push burning material out in a fountain).
