We all know that there are four types of chemical reactions.
One of them is Chemical combination. Let's learn more about it.
To demonstrate this Chemical Combination, we require
Take the sulphur with the help of a spatula.
Sulphur is yellow in colour.
When this yellow sulphur powder is heated with the help of the spirit lamp,
you will first see the powder turn to deep wheatish colour.
After a few minutes, you will see a deep wheatish salt
that burns with a blue flame.
Look here, the blue flame that is burning is sulphurdioxide gas.
This is a very dangerous gas.
If we breathe this gas we may develop lung diseases.
We will now see this experiment in the form of an equation on the board.
