The chemical changes from the following are:
PHOTOSYNTHESIS and CURDLING OF MILK.
- Photosynthesis is a chemical reaction as new products (glucose) is being formed in it.
- Boiling of water is not a chemical reaction. It is a physical change as only the physical state of water is changing and not the composition.
- Tearing of paper is not a chemical change as no new products are forming. Small pieces still remain the same paper.
- Curdling of milk is a chemical change as new product (curd) is being formed in it by the action of bacteria on the milk.
