Answers
Answer:
Photosynthesis is one of the chemical change.
Digestion is one of the chemical change.
Answer:
The following are the chemical change examples in our day to day life :
1.Digestion
2.Soap and detergent reactions
1.Digestion
Digestion is a complex process that involves thousands of chemical reactions. When you put food in your mouth, water and the enzyme amylase breaks down sugar and other carbohydrates into simpler molecules. Hydrochloric acid and enzymes break down proteins in your stomach. Sodium bicarbonate released into the small intestine neutralizes the acid and protects the digestive tract from dissolving itself.
2.Soap and detergent reactions
Washing your hands with water isn’t a chemical reaction because you’re just mechanically rinsing away grime. If you add soap or detergent, chemical reactions occur that emulsify grease and lower surface tension so you can remove oily grime. Even more reactions occur in laundry detergent, which may contain enzymes to break apart proteins and whiteners to prevent clothes from looking dingy.
