How did the properties of sulfur alone compare with the sulfur in the unheated iron sulfur combination?
Sulfur before being heated in the mixture weighs less and is less reactive than in the heated mixture.
Are iron and sulfur different?
Yes, iron and sulfur are different elements. Iron is a metal with the symbol Fe and atomic number 26, while sulfur is a non-metal with the symbol S and atomic number 16. They have different physical and chemical properties.
Is unheated sulfur and iron filings is substance or mixture?
Sulfur and iron filings together are a mixture.
Why there is no substance formed when sulfur and iron is heated?
When sulfur and iron are heated together, they react to form iron sulfide. Iron sulfide is a compound, not a mixture, so it does not show the properties of its individual elements like sulfur and iron. The formation of this compound is a chemical reaction where the atoms of sulfur and iron rearrange to create a new substance with different properties.
Why is it impossible to separate iron filings from sulphur after heating?
After heating iron filings and sulfur, they chemically react to form iron sulfide (FeS). This new compound cannot be easily separated back into its original components because it has different physical and chemical properties from iron and sulfur. Thus, it is difficult to separate iron filings from sulfur after heating.
What indivudual physical properties of sulfur powder and iron powder when they were a mixture?
the color
Is mixing iron filing and sulfur is a physical change?
It's just physical, unless you heat the mixture. The simple combination of iron and sulfur is a physical mixture: It can be separated with a magnet, and the iron and sulfur are still themselves. The situation changes if you heat the mixture hot enough to start a reaction between the sulfur and iron. If you do so, assuming the ingredients are in the right proportions, you'll have iron sulfide (a compound) and no free iron or sulfur will remain. In that case, you have a chemical reaction.
How could a student use a magnet to indicate that combining iron an sulfur to produce the mixture of iron and sulfur is a physical change?
A mixture of iron and sulfur can be separated using a magnet- the iron will be attracted to the magnet, sulfur will not. Not the that the iron could be coated with sulfur powder so an extra step is required to remove it.
Have iron and sulfur undergone change in properties after mixing?
No. Making mixtures are physical changes and the chemical substances will not change.
What are the differences between the mixture of iron and sulfur and the new compound you have made?
The mixture of iron and sulfur is a physical combination of two elements that can be easily separated by physical means, while the new compound is a chemical combination of iron and sulfur atoms that has different properties than the individual elements. The mixture retains the properties of its components, while the compound has a unique set of properties due to the formation of chemical bonds between the iron and sulfur atoms.
What happens to iron filings and sulfur powder when heated?
When iron filings and sulfur powder are heated together, they undergo a chemical reaction to form iron sulfide. The iron sulfide produced is a compound that has different physical and chemical properties compared to iron or sulfur alone.
Is the mixing of iron and sulfur a physical change or chemical change?
It is always categorized as a Physical change as no new substance with different properties forms.
Are iron and sulfur metals?
Iron is a metal, but sulfur is a non-metal. Iron is a transition metal with metallic properties such as conductivity and malleability, while sulfur is a non-metal with properties like brittleness and poor conductivity.
How did the properties of sulfur alone compare with the sulfur in the unheated iron sulfur combination?
Sulfur before being heated in the mixture weighs less and is less reactive than in the heated mixture.
Each substance in a mixture of iron and sulfur keeps its own?
properties and can be separated through physical means based on their differences in properties such as magnetism, solubility, and boiling point. Iron and sulfur can be physically separated by using a magnet to remove the iron, or by dissolving the mixture in a suitable solvent to separate the components.
Are iron and sulfur different?
Yes, iron and sulfur are different elements. Iron is a metal with the symbol Fe and atomic number 26, while sulfur is a non-metal with the symbol S and atomic number 16. They have different physical and chemical properties.
When iron and sulfur combined to form iron sulfide what change take place?
When iron and sulfur combine to form iron sulfide, a chemical reaction occurs. Iron atoms react with sulfur atoms to form a new compound with different physical and chemical properties than the original elements. The iron and sulfur lose their individual characteristics and combine to create a new substance, iron sulfide.
