What is the apearrance of unheated sulfur and iron filings?
Sulfur is a fine powder that is light yellow in color; iron filings are metallic. A mixture would be just that: a light yellow powder intersperced with metallic particles.
Hypothesis of separating iron filing and sulfur powder?
The hypothesis for separating iron filing and sulfur powder using a magnet is that iron is a magnetic material, whereas sulfur is not. By using a magnet, we can separate the iron filings from the sulfur powder based on their magnetic properties.
How do you separate a mixture of ammonium chloride and chalk powder in the laboratory?
Oh, dude, separating ammonium chloride and chalk powder? Easy peasy. So, you just gotta add water to the mixture, 'cause ammonium chloride dissolves in water while chalk powder doesn't. Then you can filter out the chalk powder 'cause it won't dissolve, leaving you with the ammonium chloride solution. Like, science, man.
What substance is made when limestone and clay are heated together?
Limestone, CaCO3 decomposes into quicklime, CaO, and carbon dioxide, CO2, when heated. The reaction is: CaCO3 + heat --> CaO + CO2.
What is observed when air is passed over heated copper powder?
When air is passed over heated copper powder, the copper powder will react with the oxygen in the air, leading to the formation of copper oxide. This reaction can result in a color change in the copper powder from its original metallic color to a reddish-brown color.
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 chili powder and iron filings a solution or a mixture?
Mixture!:)
What will you observed when A magnet is rolled in a mixture of iron filling and sulfur powder?
The iron filings will be attracted to the magnet and stick to it due to their magnetic properties. The sulfur powder will remain unaffected as it is not magnetic. You will observe the separation of the iron filings from the sulfur powder as the magnet is rolled through the mixture.
How do you separate a mixture of iron filings copper sulphate cystals and chalk powder?
Use a magnet to remove the iron filings from the mixture, then mix the remaining components with water. The copper sulfate will dissolve but the CaCO3 (chalk powder) will not. Filter the mixture to remove the chalk, then boil the water to recover the copper sulfate.
What is the apearrance of unheated sulfur and iron filings?
Sulfur is a fine powder that is light yellow in color; iron filings are metallic. A mixture would be just that: a light yellow powder intersperced with metallic particles.
What was the new substance formed after heating the iron-sulfur mixture?
The result of heating iron filings and sulfur powder mixture shows an exothermic reaction which forms a compound, iron sulfide.
Hypothesis of separating iron filing and sulfur powder?
The hypothesis for separating iron filing and sulfur powder using a magnet is that iron is a magnetic material, whereas sulfur is not. By using a magnet, we can separate the iron filings from the sulfur powder based on their magnetic properties.
What the differences and similarities between iron filings sulfur yellow powder and mixture of iron and sluphur?
Iron filings and sulfur yellow powder are pure substances, while a mixture of iron and sulfur is a combination of two elements physically mixed together. When iron and sulfur are combined, they can be easily separated by physical means, whereas iron filings and sulfur powder cannot be separated without a chemical reaction. The similarities lie in the chemical elements present (iron and sulfur) in all three substances.
What is the chemical equation for a heated iron fillings and sulfur powder?
When heated, iron filings (Fe) react with sulfur (S) to form iron sulfide (FeS). The chemical equation for this reaction is: Fe + S -> FeS.
How will you separate chalk powder iron fillings and naphthalene?
Use a magnet to remove the iron filings... Warm (do not boil) the remaining mixture to evaporate the naphthalene.
What happens when a little of ion powder mix with sulphur powder is being heated?
Do you mean iron powder mixed with sulphur powder? Fe(s) + S(s) ---> FeS (iron sulfide)
What is mixture mean?
A "mixture" is a group of several chemicals that have been mixed together in such a way they can be easily separated, usually without altering the state of matter of any of the chemicals. Iron filings and sulfur powder would be a mixture; you can separate the two with just a magnet. Similarly, sand and sulfur powder would be a mixture. Just put it in water; the sulfur will float and the sand will sink.
