What is the chemical composition of alkalie?
Alkali is a basic, ionic salt of an alkali metal or alkaline earth metal element. Thus, the chemical composition of an alkali is: alkali metal,hydrogen,oxygen,carbon.
Is bending metal sheets a chemical change?
No. It is a physical change because the chemical composition of the metal remains the same.
Is a metal surface being ground a chemical change?
A metal Surface being ground is a physical change, not a chemical change.
Is cutting a bar of sodium metal with a knife a chemical change?
Yes, cutting a bar of sodium metal with a knife is a physical change, not a chemical change. The chemical composition of the sodium metal remains the same before and after cutting. The change is only in the physical state of the metal.
Is hammering copper metal a physical or chemical change?
It is a physical change because you are changing the shape of the metal.
Is a piece of metal is bent in half a chemical change?
It is a physical change because only its shape changed, not its chemical composition.
Is soft metal chemical property?
Softness is a physical property of metals, not a chemical one. The softness of a metal is determined by its crystal structure and the presence of defects or impurities in the metal's lattice structure, rather than its chemical composition.
Why fruit produces electricity?
This is due to an electro-chemical reaction between the chemical composition of the fruit involved and the particular metal that's used as an electrode.
Is corroding metal a chemical change?
Yes, corroding metal is a chemical change because it involves a chemical reaction between the metal and substances in its environment, such as oxygen or water. This reaction causes a change in the composition and properties of the metal.
Is bending a metal rod chemical or physical change?
Physical Change, the metal has the same chemical structure and only the shape of the bar has changed
Is metal rusting a physical change in matter?
Yes, metal rusting is a chemical change in matter. It involves the metal reacting with oxygen in the presence of moisture to form a new compound (rust), which changes the chemical composition of the metal.
When Metal is drawn out into a wire is it a chemical change or physical change?
When metal is drawn out into a wire, it is a physical change. This process involves altering the shape and form of the metal without changing its chemical composition. The metal retains its properties, such as conductivity and malleability, even after being transformed into wire.
