No. Making mixtures are physical changes and the chemical substances will not 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.
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.
For the allotropes of sulfur see this link.
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.
Selenium and tellurium are similar to sulfur.
It is always categorized as a Physical change as no new substance with different properties forms.
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.
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.
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.
ironsulphide
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.
Yes. Any compound present in a mixture retains its own properties.
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.
probably sulfur
Selenium has similar properties to sulfur as they are both in the same group on the periodic table (Group 16) and share similar chemical reactivity and properties.
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.
This is a chemical change because a new substance, iron sulfide, is formed with different properties compared to its original components, iron and sulfur.
