What are fake flowers made of?
It is made of sodium polyacrylate, a water-absorbing polymer.Water and compressed air come out of a nozzle. The air atomizes the water. Then, the expanding air cools the water, very quickly. The water then begins to freeze while falling to the ground.
Why is sodium is stored with keroesene?
The kerosene prevents the sodium from coming in contact with air or water. If sodium touches air it will oxidize and ruin the sample. If it touches water it can catch fire and even explode.
Why is sodium not used for cookery?
Sodium reacts with water or air and will burn and explode. Hence sodium in not used in cookery.
What happens when sodium chloride is left expoed to air?

Why sodium metal is stored in kerosene?
Sodium is extremely reactive. It oxidizes rapidly in air and reacts violently with water. The kerosene prevents the sodium from coming in contact with air, water, or other substances that might oxidize it.
Why is sodium put in oil?
Sodium is very reactive in water. Thus to prevent it from reacting with air and water, it is stored in oil.
Why is sodium difficult to extract?
Sodium is a group one metal which means it is highly reactive. If you have ever seen sodium placed into water you will see it goes off with a bang. The problemm with extracting sodium is water vapor in the air (humidity). Sodium will react with water extreamly easerly and quickly. For that reason it is hard to extract sodium as it reacts with the moisture in the air.
Why is sodium packed in polythene?
Sodium is very reactive, and will react with the water in the air. Also, if it got a lot of water on it, the sodium would cause a fire or explosion.
Why shouldn't sodium be kept open to the air?
Sodium is very reactive and easily react with oxygen or water.
Why sodium is stored in kerosene?
The kerosene prevents the sodium from coming in contact with water and air. Sodium is very reactive. If it touches air it will oxidize, ruining the sample. If it touches water it will burst into flames.
Why must sodium be stored under paraffin?
Sodium reacts with moisture, it will eventually turn to sodium hydroxide from moisture in the air. It reacts violently with water.
Does sodium react?
Yes, it reacts with the oxygen in the air and water very violently.
