Is rusting iron example of chemical change?
Yes, it is.
What property is an example of rusting?
It's an example of a chemical change. Rusting is a chemical process by which iron metal reacts with oxygen in the air to produce iron oxide, otherwise known as rust. A chemical change means you end up with something you didn't have before. Every chemical reaction has an equation associated with it, and the equation for rusting iron is:4Fe + 3O2 --> 2Fe2O3
Is rusting of an iron fence physical change?
yes. rust is a chemical change that occurs when you mix iron, air, and water. it reacts with the iron and actually erodes it. a n example of a physical change would be the bending or cutting of iron.
Why the rusting of an iron pole is not physical change?
The rusting of an iron pole is a chemical change. An example of a chemical change would be crumbling a piece of paper. When you are crumbling this piece of paper, the contents of the paper have not change and you are able to uncrumble the paper there is no difference except the paper has wrinkles. :) However in an example of chemical change like a metal rusting, you cannot un-rust it, it was chemically changed. Another example of a chemical change would be burning a piece of paper to ashes.

Is rusting iron example of chemical change?
Yes, it is.
Is The magnetization of an iron rod an example of a chemical change?
No. Iron is naturally magnetic.
Why rusting of iron is chemical change?
Yes. Iron corrodes because oxygen ions attach to iron atoms to make iron oxide
Is iron rusting a chemical or physical change?
Iron rusting is a chemical change: oxidation of the metal by oxygen in the air or water. When iron 'rusts' it oxidises. This is a chemical change, a physical change is when a molecule changes state, for example iron melting and going from a solid to a liquid.

What an example of a physical change?
When it combines with Oxygen. Commonly called Rust.
Is rusting metal a physial change?
No it is chemical. The metal (for example Iron, Fe) reacts with Oxgen Gas to produce Iron Oxide. You can also tell it is a chemical change because there is a colour change.
What is the chemical change the change of?
A chemical change is when one or more objects combine to form a new object. For example, an iron nail can combine with the oxygen in the air to form iron oxide, or rust.
What is an example of a physical change and a chemical change for iron?
Physical change: bending. Chemical change: Rusting (oxidation). An example of both in one item: A wrought iron fence was heated and bent into a decorative pattern. After 20 years, the fence shows evidence of deep rusting, especially on decorative curves.
