Why rusting of iron is chemical change?
Yes. Iron corrodes because oxygen ions attach to iron atoms to make iron oxide
Which of these is a chemical change copper melting or water freezing or iron rusting or gas condensing?
The only example of a chemical change in the list is iron rusting. The other three are all examples of physical changes.
Why rusting of iron is a irreversible change?
Rusting is a irreversible change although you can get products which can get rid of it.
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.

rusting of iron
Why rusting of iron is chemical change?

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.
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

Why is rusting iron a chemical change what is classifications?
Because the rusting of iron is based on a chemical change, a reaction of oxydation.
Is metal rusting a physical change in matter?
The rusting of Iron is a chemical change as Iron reacts with Oxygen to form Iron Oxide [Rust]
Why rusting of iron is a irreversible change?
Rusting is a irreversible change although you can get products which can get rid of it.
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.
