Answer 1

Answer:

this is a chemical equation showing the rusting of iron

Explanation:

The rusting of iron is a chemical change because it is two substances reacting together to make a new substance. When iron rusts, iron molecules react with oxygen molecules to make a compound called iron oxide. Rusting would only be a physical change if iron molecules remained pure iron throughout the process.Mar 9, 2018

Answer 2

Answer:

This is the process of rusting of Iron.

Explanation:

In this reaction 4 iron molecules react with 3 oxygen molecules in the presence of Water to form 2 molecules of hydrated iron(111)oxide which is also called as rust.

Here,iron(111) shows iron's oxidation state +3. I write hydrated there in product formed is because product produced also has water molecules in it.
