Is iron a chemical or physical change?
Iron is a chemical element, not a "change".
Is an iron a chemical or physical change?
Iron is a chemical element, not a "change" !
Is steel an element or a compound?
It is neither an element not a compound. Steel is an alloy. An alloy is a mixture of a metal and another element. In the case of steel, it is principally iron (an element), with about 0.2% to 2,0% carbon ( an element), mixed in. Other elements can be mixed in , e.g. chromium to form Stainless Steel, or Tungsten to form hard wearing steel.
Mars is often described as the Red Planet because of what element mixed with oxygen on its surface?
The red colour is caused by iron compounds in the soil. Iron is bonded to oxygen, not mixed with it.
Is iron physical changes or chemical changes?
Iron is a chemical element, not a change.
Can a material change from one substance to another during a chemical reaction?
"Substance" is too fuzzy a word. Chemical reactions can change materials into other compounds, for example shiny iron into rust (Fe2O3). But it cannot change an element into another element. A nuclear reaction can do that, for example uranium into plutonium.
When iron is mixed with carbon is it called zinc?
No, when iron is mixed with carbon it forms steel, not zinc. Zinc is a separate element and does not come from the combination of iron and carbon.
How many oxygen atoms are in iron?
There are no iron atoms in oxygen. Oxygen is an element in itself so it can not be complicated by another element unless it becomes a molecule of something else. Usually iron that has been mixed with oxygen can be form an iron oxide.
Is iron dangerous when mixed with another element?
Yes it could be depending on what it is mixed with. Please talk to your science teacher before trying anything., like mixing up stuff to see what happens that is dangerous. Please read lab safety manual
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.
Can the element cobalt be mixed with any other element?
Yes, cobalt can be mixed with other elements to form alloys. It is commonly mixed with other metals such as iron, nickel, and chromium to create alloys with specific properties for various industrial applications.
Is iron a homogeneous or heterogeneous mixture?
Iron is an element; it cannot be broken down into smaller atoms. Every atom in iron is a iron atom so it is homogenous.
