|Class 10 Chemistry Chemical Reactions and Equations||Chemical equation|
Describing all of the chemical reactions that occurs around us in words is quite impossible.
Like if you want to depict rusting of iron. Instead of writing the phenomenon in sentences, you can simply write it as
This is known as word equation. And it itself describes the whole phenomenon of rusting. Through this we can conclude that iron on reacting with oxygen and water present in atmosphere undergoes chemical transformation and gets converted to ferric oxide i.e. Rust.
Points to be kept in mind while writing chemical reaction.
