Did you know?
Did you know that there are many types of chemical changes besides burning a substance? Two specific examples include:
1. Rusting: When iron or any other metal reacts with oxygen in the presence of moisture, it undergoes a chemical change called rusting. This results in the formation of iron oxide, which not only damages the metal but also changes its properties.
2. Digestion: The process of digestion in our body involves several chemical changes. Enzymes present in our digestive system break down complex molecules of food into simpler substances, such as carbohydrates, proteins, and fats. These reactions are essential for extracting nutrients that our bodies require for energy and growth.
