Which metal is kept immersed in kerosene for storing?
Sodium is a metal that is commonly kept immersed in kerosene for storing because it reacts violently with water and oxygen in the air. Placing it in kerosene helps prevent these reactions and keeps the metal stable.
Why white phosphorous has to be kept in water?
White phosphorus should be kept in water or under a layer of oil to prevent its exposure to air, as it is highly reactive and can spontaneously ignite upon contact with oxygen. Storing it submerged helps to reduce the risk of accidental fires and exposure to air. Additionally, white phosphorus can release toxic fumes, and storing it in water can help to contain these fumes and prevent them from dispersing.
Why do sodium kept immersed in kerosene oil do not burn?
Sodium reacts violently with water, releasing hydrogen gas and forming sodium hydroxide. When sodium is kept immersed in kerosene oil, it is isolated from water, preventing the reaction from occurring. Kerosene oil acts as a barrier to keep oxygen away from the sodium, further preventing combustion.
What is white phosphorus is always kept under water?
White phosphorus is a highly reactive, pyrophoric substance that ignites spontaneously in air. It is stored underwater to prevent contact with oxygen and reduce the risk of ignition. White phosphorus can react violently with oxygen, leading to fires and potential harm.
If a stone is immersed in a container of water the water level is?
rises
What liquid is yellow phosphorous normally kept in to prevent it from igniting?
Water.

When Sodium metal kept immersed in kerosene as it catches fire if exposed to air but why is it not kept in water?
Because is reacts with water causing hydrogen to be released and catch fire. Na + H2O = NaOH + H also it will also float on water having a density of 0.98 g/cm^3
Why is sodium kept in oil?
Sodium is kept immersed in kerosene because it reacts so vigorously that they catch fire when kept in the open. Hence to protect them and to prevent accidental fires, they are kept immersed in kerosene oil.

Which nonmetal is stored in water?
Phosphorous
When an object is said to be immersed in water does this mean it is partially submerged or completely submerged?
When an object is immersed in water, it means it is completely surrounded or covered by the water.
If a stone is immersed in a container of water the water level?
rises
What is a good sentence for immersed?
I immersed the boiled egg in cold water to cool it down
Why the stems of a harvested jute plant are kept immersed in water for a few days?
The stems of harvested jute plants are kept immersed in water for a few days to facilitate the retting process. Retting helps to break down the pectin and other substances that bind the fibers to the stem, making it easier to separate the valuable jute fibers. This process also helps in softening the stalks and improving the quality of the fibers by reducing impurities. Ultimately, immersing the stems in water enhances the efficiency of fiber extraction.
