Iron is an element and contains only atoms with the same number of protons in their nuclei.
they differs only in their chemical composion in carbon-hydrogen-oxygen!!
Who is laboratary
Iron (Fe) is a chemical element.
Rusting of iron is chemical. It is the combination of oxygen with the iron, creating a different chemical: rust or iron oxide.
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.
The chemical symbol for iron is Fe and the chemical symbol for nickel is Ni.
rust is a chemical change for iron
Iron is a chemical element, not a "change".
Iron is a chemical element, not a "change" !
The chemical formula of iron pyrite is FeS2.
Rusting of iron is a chemical change. It occurs when iron reacts with oxygen and water in the presence of moisture, forming iron oxide (rust). This process involves a chemical reaction that changes the chemical composition of the iron.
FeS is not a chemical equation but a chemical formula; FeS is the chemical formula of iron sulfide.
