When iron rusting is an example of a what change?
When iron rusts, it undergoes a chemical change. This is because the iron reacts with oxygen in the air to form iron oxide, which has different chemical properties compared to the original iron.
Have iron and sulfur undergone change in properties after mixing?
No. Making mixtures are physical changes and the chemical substances will not change.
Jim drops an iron magnet during a chemistry lab experiment and she finds that it is no longer magnetic so what has happened in terms of its properties?
The iron magnet lost its magnetism, possibly due to undergoing a physical change that disrupted its magnetic alignment. This change could have disrupted the magnetic domains within the iron, causing it to no longer exhibit magnetic properties.
Did the properties of the iron and sulphur change when you mixed them?
No, the properties of iron and sulfur did not change when they were mixed physically together. Each substance retained its own individual properties as they remained physically mixed but not chemically bonded.
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 the color of iron wire a physical or chemical change?
The color change of iron wire when it rusts is a chemical change because it involves a reaction with oxygen in the air to form iron oxide. This new substance has different properties than the original iron.
is iron rusts a chemical or physical change?
The rusting of iron is a chemical change. It involves the reaction of iron with oxygen in the presence of moisture to form iron oxide (rust), which has different chemical properties compared to the original iron.
Is iron rusting a physical or chemical change?
Iron rusting is a chemical change because it involves a chemical reaction between iron and oxygen to form iron oxide (rust). This results in a new substance with different properties than the original iron.
Is rust an example of a chemical change or a physical change?
rusting is oxidation, so it is definitely a chemical change
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.
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.
Is the reaction of iron with hydrochloric acid a chemical change?
Yes, the reaction of iron with hydrochloric acid is a chemical change. It results in the formation of iron chloride and hydrogen gas, which are different substances with distinct properties from the original iron and hydrochloric acid.
