Answer:

Common signs of a chemical reaction include:

1. Change in color

2. Production of light or heat

3. Formation of gas (bubbles)

4. Formation of a precipitate

5. Change in temperature

6. Emission of sound

In the context of lighting fireworks, the most relevant examples of evidence would likely include:

  • Production of light: Fireworks emit bright lights and colors when ignited.
  • Emission of sound: Fireworks produce loud sounds, such as bangs or whistles.
  • Change in color: The explosion of fireworks often results in vibrant colors in the sky.
  • Formation of gas: The explosion generates gases that expand rapidly, contributing to the visual and auditory effects.

So, the specific evidence from Table 2 that would show lighting fireworks is a chemical reaction would be production of light and emission of sound.
