Cotton is the seed fiber of the Gossypium plant of the Malvaceae family and is native to subtropical regions. The plant resembles a shrub and can reach 6 meters in height when grown in tropical areas, usually 1 to 2 meters.
The flowers are milky white, turn dark red shortly after flowering, then fade, leaving small green bolls, called cotton bolls. There are cotton seeds inside the cotton bolls. Cottonseed fluff grows from the skin of the cottonseed and fills the inside of the cotton bolls. When the cotton bolls mature, they open, revealing the soft fibers. The fiber is white or white with yellow, is about 2 to 4 centimeters (0.75 to 1.5 inches) long, and contains about 87 to 90% cellulose, 5 to 8% water, and 4 to 6% water. other substances.
Iron (Ferrum) is a starmetallic element with an atomic number of 26. The chemical formula of iron is: Fe, and its English name is iron. The average relative atomic mass is 55.845. Pure iron is white or silvery white with a metallic sheen. It has a melting point of 1538°C and a boiling point of 2750°C. It is soluble in strong and moderately strong acids, but insoluble in water.
Iron is widely distributed in life, accounting for 4.75% of the Earth's crust, ranking fourth after oxygen, silicon, and aluminum. Pure iron is a flexible, ductile silver-white metal used to make the cores of generators and electric motors.
Iron and its compounds are also used to make magnets, medicines, inks, pigments, abrasives, etc., and are among the "black metals" of industry (both others are chromium and manganese) (in reality pure (the cast iron is silvery white and the elementnt iron is called "black metal" because the surface of iron is often covered with a protective film whose main component is black iron oxide).
In addition, the human body also contains iron. The +2 valence ferrous ion is an important component of hemoglobin and is used for oxygen transport.
In short:
It literally weighs the same, but if you change it to the weight when you hold it, it will be different.
Consider the shape first. Cotton can be deformed at will, is soft and compressible, so "if" you have to choose, you must choose cotton, because as long as the support area is large, it can be very light
But iron is different. Iron is a solid and cannot be deformed. If you have to take it, a ton is really a ton, and the thief wins, don't underestimate him.
Final answer:
The same weight, but the situation must be taken into account
The main componentiron is the element iron.
Element iron, atomic number 26, chemical formula of iron: Fe. Pure iron is white or silvery white with a metallic luster. It has a melting point of 1538°C and a boiling point of 2750°C. It is soluble in strong and moderately strong acids, but insoluble in water. Iron has a price of 0, a price of +2, a price of +3, and a price of +6. Among them, price +2 and price +3 are more common, and price +6 is rare.
Iron is widely distributed in life, accounting for 4.75% of the earth's crust, ranking fourth after oxygen, silicon and aluminum. Pure iron is a silver-white, flexible and ductile metal. It is used to make the cores of generators and motors. Iron is also used in its compounds. It is used to make magnets, medicines, inks, pigments, abrasives, etc. It is one of the “black metals” of the industry (the other two are chrome and manganese) (in fact, pure cast iron is silvery white, and the iron element is called "black metal"). “Black metal” refers to the fact that the surface of iron is often covered with a protective film whose main component is black iron oxide). Additionally, the human body also contains iron. The +2 valence ferrous ion is an important component of hemoglobin and is used for oxygen transport.
1. Used in pharmaceuticals, pesticides, powder metallurgy, thermal hydrogen generators, gel propellants, combustion activators, catalysts, water cleaning adsorbents, sintering activators, products powder metallurgy and various machinery parts products, cemented carbide materials. products, etc
2. Pure iron is used to make the cores of generators and electric motors, reduced iron powder is used in power metallurgy.dres and steel is used to make machines and tools. Additionally, iron and its compounds are also used to make magnets, medicines, inks, pigments, abrasives, etc.
3. Used as a reducing agent. Used in the preparation of iron salt. Also used in the preparation of electronic components.
4. Used as a nutritional supplement (iron fortifier).
5. Used as a filler in epoxy adhesives to prepare casting repair glue. Often used as a reducing agent. It is widely used in electronics industry, powder metallurgy and machinery industry. FHY80.23 is mainly used for oil bearings. FHY100.25 is mainly used for medium and low density mechanical parts. HFY100.27 is mainly used for high density mechanical parts.
