Is heating up sulfur a chemical change?
It is not a chemical change, unless you heat it sufficiently to make it catch fire.
What is a chemical change a.Heating of ZnO b.magnetization of iron c.heating of sulfur d. radioactivity?
heating of sulfur in presence of oxygen (or air) is a chemical change.
When heating sulfur what reaction physical or chemical?
When heating sulfur, a chemical reaction occurs. Sulfur undergoes a phase change from solid to liquid to gas as it is heated, but this is still considered a chemical change because the molecular structure of the sulfur is altered in the process.
Is heating sulfur a physical or chemical change?
Heating sulfur is a physical change. You're not changing the chemical composition of the sulfur, just the temperature. Now if you heat it to its boiling point and and it changes to a vapor it's a chemical change because you've changed its state of matter.(Actually changing the state of matter of an object is still a physical change, as it does not change the chemical composition of the element)
Why is heating of sulphur considered as a physical change?
Simply heating (warming) sulfur could be a physical change if nothing happens to the sulfur other than it just getting warmer, and when you remove the heat, it stays as the original sulfur. However, more likely than not, heating sulfur will cause a CHEMICAL change where the sulfur combusts and turns into sulfur dioxide (SO2).
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.
Why is heating copper sulfate a chemical change?
Heating copper sulfate causes a chemical change because it leads to the compound decomposing into different substances, namely copper oxide and sulfur dioxide. This change alters the chemical composition and properties of the original compound, indicating a chemical reaction has occurred.
Is heating of powdered sulphur a physical or a chemical change?
Heating sulfur (yellow form, S8) gives initially a red liquid which solidifies as a rubbery mass. This is termed plasic sulfur. This slowly reverts back to the yellow form. These changes are considered to be physical changes although the molecular form changes (it is still sulfur) from S8 to a metastable polymeric plastic sulfur. There is often ignition of the sulfur - to form sulfur dioxide this is most definitely a chemical change.
Is burning sulfur a physical or chemical change?
It is a chemical change, an oxidation 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.
Does heating copper II sulfate produce a chemical change or physical change?
Heating Copper Sulfate gently drives off the water of crystallization leaving an amorphous white powder. This is purely a physical reaction. Heating this powder strongly will cause a chemical reaction liberating sulfur dioxide and oxygen, leaving black copper(II)oxide: 2CuSO4 >2CuO + 2SO2 + O2
Is Heating a hydrous salt to obtain an anhydrous salt a chemical or physical change?
if you mean epsom salts (magnesium sulfate) then heating it will result in a decomposition reaction, where magnesium oxide (s) and sulfur trioxide (g) is formed. The decomposition reaction is therefore a chemical change.
