In terms of clothes, chemistry can add warmth to life. Nylon is a kind of resin with amide bond in its molecule, which is not found in nature and needs to be obtained by chemical methods. Polyester, a synthetic fiber made of ethylene glycol and dimethyl terephthalate, and many other similar fabrics enrich people's wardrobes. Chemistry is equally important in food. Steamed bread made of soda ash is soft and delicious. All kinds of drinking wine are made from grain and other raw materials through a series of chemical changes. Betel nut is a favorite food of ethnic minorities. Before eating, it must be soaked in hydrated lime and cut into small pieces. After a certain time, it will be cut into small pieces.
Because of chemistry, our house has colorful decorations. Quicklime is soaked in water to become mature lime, and coated on the floor to become white and hard calcium carbonate, which covers the yellow of the soil and makes the house clean and bright. Only when steel is chemically refined can we use iron products. Only when the oil is chemically treated can we use lightweight plastics. Only when the clay is chemically calcined can we make the house have a beautiful tile surface.
Chemical reaction is the driving force of vehicle movement. Without the heat released by fuel combustion, the vehicle can't run at all. Chemical energy is the most primitive source of energy for their movement. Even with electricity as power, we can't forget the great contribution of chemical energy. At present, chemistry is still the life of transportation and still plays an important role in people's travel.
Chemistry exists in all kinds of activities in people's lives all the time. Detergents are phosphorus-containing compounds, which are widely used in people's cleaning appliances, textiles, papermaking, pesticides and other departments. Sulfuric acid is produced by the combustion of pyrite as an important chemical raw material. The purity of gold is tested by aqua regia. Remove the oxide scale by pickling. Emulsified rubber of gasoline is used as adhesive. Glass is carved with hydrofluoric acid. The fire was put out by foam extinguisher. Refreshing soda water is made by dissolving carbon dioxide under pressure, which is how delicious baking soda is made.
Chemistry itself is a magic mirror, which skillfully combines more than 100 elements to form a magical and beautiful world. It makes carbon form two completely different worlds: beautiful and noble diamonds and soft and cheap graphite, and it also plays jokes on people. People will keep groping for progress in his jokes, and our life will enter a bright future with its progress.
