Is heating a mixture of iron and sulfur physical or chemical change?
Heating a mixture of iron and sulfur results in a chemical change. When heated, the iron and sulfur react to form iron sulfide, a new compound with different properties than the individual elements. This transformation involves the breaking and forming of chemical bonds, indicating that a chemical reaction has occurred. Thus, the process is not merely a physical change but a chemical one.
What species would be expected to have chemical properties most similar to oxygen?
a) nitrogen b) fluorine c) oxide iond) nitride ion e) sulfurOut of these options, the correct answer is e) sulfur. Sulfur is the chemical species that would be expected to have a properties most similar to oxygen.
What states of change is unheated sulfur?
For the allotropes of sulfur see this link.
Is strontium similar with sulfur?
Strontium and sulfur are both chemical elements, but they are not similar in terms of their properties or behavior. Strontium is a metal that is in the same group as calcium, while sulfur is a nonmetal that is commonly found in compounds like sulfides and sulfates. They have different physical and chemical properties.
What elements have properties similar to sulphur?
Selenium and tellurium are similar to sulfur.
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.
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.
Why iron sulfur are heated and form a non magnetic shiny grey substance is chemical change?
Heating iron and sulfur causes a chemical reaction to occur, resulting in the formation of iron sulfide, a new substance with different properties than the original elements. The change in color, from the original yellow of sulfur and silver-gray of iron, and the change in magnetic properties indicate a chemical change has taken place.
Is a lump of roll sulphur being crushed a physical or chemical change?
Crushing a lump of roll sulfur is a physical change, as the chemical composition of the sulfur remains the same. The process only alters the physical state of the sulfur without changing its chemical properties.
Word equation for mixing sulfur and iron filings?
ironsulphide
Why is sulfur burning a chemical change?
Sulfur burning is a chemical change because it involves a chemical reaction that results in the formation of new substances. When sulfur burns, it combines with oxygen in the air to form sulfur dioxide, which is a different chemical compound with different properties than sulfur alone.
Does sulfur in the mixture still have the properties of pure sulfur?
Yes. Any compound present in a mixture retains its own properties.
Is sulfur combined with oxygen produces sulfur dioxide a physical change?
This is a chemical change because there is a molecular change in the composition. A physical change results when the size, shape, phase, texture etc. of a substance changes. Liquid water heated to water vapor is a physical change.
Is Sulfur argon and sodium which has chemical properties like oxygen?
probably sulfur
When a mixture of iron and sulfur are heateda compound called iron sulphide is producedwhat type of change is this?
This is a chemical change because a new substance, iron sulfide, is formed with different properties compared to its original components, iron and sulfur.
When iron and sulfur combine to form iron sulfide what change takes place?
When iron and sulfur combine to form iron sulfide, a chemical change takes place. This reaction is characterized by the formation of a new substance with different properties from the original iron and sulfur, including a change in color and the release of energy in the form of heat.
Which elements have similar properties to sulfur?
Selenium and tellurium are elements that have similar chemical properties to sulfur. They belong to the same group (Group 16) in the periodic table, known as the chalcogens, and share similar chemical reactivity and properties with sulfur.
