The process of polymerization involves a chemical reaction that links together small molecules known as monomers to form larger molecules known as polymers. This is a protective layer that can prevent further corrosion of the metal. When bronze is exposed to air and moisture over time, it can undergo a chemical reaction that results in the formation of a greenish-brown layer known as a patina.
This changes the properties of the metal, such as its conductivity or resistance to corrosion. Electroplating of metalsĮlectroplating is a process in which a metal is coated with a thin layer of another metal through an electrochemical reaction.
EXAMPLES OF CHEMICAL CHANGES THAT HAPPEN EVERYDAY SERIES
The decay of organic matter such as food waste or leaves involves a complex series of chemical reactions that break down the organic molecules into simpler molecules such as water, carbon dioxide, and methane. The combustion of gasoline produces carbon dioxide and water vapor as byproducts. When gasoline burns in an engine, it starts a chemical reaction with oxygen in the air, producing energy in the form of heat and motion.
The ripening of fruit involves a series of chemical reactions that break down complex organic molecules such as starch and acids into simpler molecules such as sugars, which give the fruit a sweeter taste. When copper is exposed to acidic or humid conditions, it can undergo a chemical reaction that results in the formation of greenish-brown copper carbonate or copper sulfate. When silver is exposed to air and sulfur compounds, a chemical reaction occurs that results in a darkening of the metal known as tarnishing. This breaks down the pigment and lightens the hair color. When hair is bleached, a chemical reaction occurs between the bleach and the melanin pigment in the hair. This chemical change alters the texture and taste of the egg. When an egg is cooked, the heat causes the proteins in the egg to denature and coagulate, resulting in a solid and opaque structure.
This is a chemical reaction that is used in the production of alcoholic beverages such as beer and wine. Fermentation of alcoholįermentation is a process in which sugars are converted into alcohol and carbon dioxide by microorganisms such as yeast. Enzymes in the digestive system catalyze these reactions, breaking down carbohydrates, proteins, and fats into glucose, amino acids, and fatty acids. It involves a series of chemical reactions that break down food into simpler molecules that can be absorbed by the body. Digestion of foodĪnother important example of chemical change is the process of digestion. The chemical reaction converts the complex organic molecules in wood into simpler molecules such as carbon dioxide, water vapor, and ash. This process releases energy in the form of heat and light. When we burn wood, it undergoes a chemical reaction with oxygen in the air. It is the most common example of chemical change in daily life. This results in a reddish-brown layer of iron oxide on the surface of the metal. When iron is exposed to oxygen and moisture over time, it undergoes a chemical reaction known as rusting. Iron is an example of chemical change in daily life. Here are 20 examples of chemical changes.
