Answer:
Examples of chemical reactions in everyday life include photosynthesis, rust
Rust is exothermic
All combustion reactions (such as the burning of coal) are exothermic. Incredibly, the reaction between iron and moist air that produces rust is a very exothermic process and generates lots of heat.
Photosynthesis is endothermic
Photosynthesis is an endothermic reaction. This means it cannot occur without energy (from the Sun). The light required is absorbed by a green pigment called chlorophyll in the leaves.
