Signs of Chemical Reactions

1. Changes in color
2. Changes in physical state
3. Emission of light of heat
4. Combustion
5. Formation of gas

Examples of Chemical Reactions

There were multiple examples of endsthermic and exothermic reactions. One example shows a substance growing when heated, which would be endothermic if you focus on the heat transferring into the substance.
