Some impurities ,or unwanted substances ,are less dense than water ,so they float in water and can be washed away.Others ,like sulfur ,can be burned away.

What kind of properties can be observed only when the substances in a sample of matter are changing into different substances?
Yes, chemical properties can be determined only experimentally, as a consequence of chemical reactions. But, today chemists can made some predictions about chemical properties of a substance on the basis of existing data about chemical and physical properties.
Is luster a typical physical property of metals?
Luster is a physical property of crystals.
Is Tin a semi-metal?
"Very malleable silver white metal that forms a protective oxide film on its surface that prevents it from reacting with oxygen." http://environmentalchemistry.com/yogi/periodic/Sn.html#Physical
How do scrap yards separate metals from non magnetic metals?
They use electromagnets to separate magnetic metals from non-magnetic metals/materials in scrapyards.
What are properties of metaloids?
As their name suggests, metalloids possess characteristics of metals and nonmetals. Typical characteristics of metals include a shiny luster, some degree of malleability and an ability to conduct electricity or heat. Nonmetals are typically nonlustrous, brittle and poor conductors of electricity.
Why plutonium is a metal?
Because the general physical and chemical properties of plutonium are specific for metals.
What is an element whose physical properties are generally opposite to metals?
These chemical elements are nonmetals.
Metals that share both physical and chemical properties are called?
families
What is a property of metals?
Physical properties of metals include: luster, malleability, and ductility. Chemical properties include: forming cations, and reacting with nonmetals to form ionic compounds.
What are the physical properties and chemical properties of elements and how are they grouped on the periodic table?
metals, non-metails and metalloids
Name of metals their chemical properties and physical properties and their uses?
The question is too broad and needs to be more specific
Why is americium metal?
Americium is considered a metal because has the general chemical and physical properties of metals.
What are the physical and chemical properties of solder?
Solder is a mixture of various metals. Its physical property is that it melts at fairly low temperatures, not so low that it melts when this is undesired. Its reactions are the same as the component metals.
Why is iron scandium and technetium metals?
These elements have the general chemical and physical properties of metals: they are dense, hard, conductive, lose electrons etc.
Is being good energy conductors a chemical property of some metals?
No, being good energy conductors is a physical property of some metals, not a chemical property. Chemical properties describe how a substance interacts with other substances and undergoes chemical reactions, while physical properties describe the characteristics and behavior of a substance without changing its chemical composition.
What are physical and chemical properties of non metals?
Please refer to the related link below for a very informative article.
Is converting iron to a steel alloy a physical change?
It is a physical change as an alloy is a solid solution made from various metals. As you can still separate these different metals after the alloy is made it is a physical change and not a chemical change.
