Bot GPT 3.5 As an AI language model, I don't have access to personal data or observations. However, I can provide you with a general list of indicators of chemical change that are commonly observed in experiments and observations. These may include:
1. Formation of a precipitate: A solid substance is formed when two solutions are mixed.
2. Color change: The color of a substance or solution changes, indicating the formation of new substances.
3. Formation of a gas: Bubbles or gas evolution occur when two substances react.
4. Temperature change: Heat is released (exothermic) or absorbed (endothermic) during a chemical reaction.
5. Odor change: A distinct smell is produced as a result of the reaction.
6. Change in pH: The acidity or alkalinity of a substance or solution changes.
7. Light emission: Production of light or change in the intensity or color of light emitted.
8. Change in state: Change from solid to liquid, liquid to gas, or any other physical state change due to a chemical reaction.
It's worth noting that these indicators do not apply universally to all chemical reactions but are commonly observed signs of a chemical change occurring.
