Why if a piece of sodium metal is cut with a knife the shiny metal at the cut soon goes dull?
When sodium metal is exposed to air, it reacts with oxygen to form sodium oxide and sodium hydroxide. This reaction produces a layer of oxide and hydroxide on the surface of the metal, which gives it a dull appearance. It is the reaction with oxygen in the air that causes the shiny metal to become dull shortly after being cut.
Why are pipes dull black?
Pipes are often dull black due to the oxidation that occurs on the surface of the metal. When exposed to air and moisture, the iron in the pipes can react with oxygen to form iron oxide, giving them a black appearance. Additionally, pipes are often painted or coated with a black finish for corrosion resistance and to protect the metal from environmental factors.
Why is it when you cut s piece of sodium metal the shiny metal soon goes dull?
When a piece of sodium metal is cut, it is exposed to air, which contains moisture and oxygen. This leads to the formation of sodium oxide and sodium hydroxide on the surface of the metal, which gives it a dull appearance. The shiny surface of the sodium metal reacts with the surrounding air and moisture, forming these compounds which are not shiny.
If a piece of sodium metal is cut with a knife the shiny metal at the cut soon goes dull?

Why is it when a piece of copper is folded squashed and heated in air only the outside of the copper is black?
The black coating you see is a coating of copper oxide, which forms when the hot metal reacts with air. no air can reach the inside, so it does not react to form black copper oxide.
What metal is black does not rust and is magnetic?
The metal that fits this description is iron. When iron is exposed to air and moisture, it forms a black layer called magnetite, which protects it from further corrosion. Additionally, iron is a ferromagnetic material, meaning it can be magnetized.
