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.
