sodium and potassium are kept under kerosene surface to protect them from rust since the are very active elements and react with O as soon as being exposed to it.
To keep them from coming in contact with water or air.
Metals such as sodium and potassium react rapidly with air and violently with water.
Any of the alkali metals or calcium and heavier alkaline earth metals could be preserved by such storage.
Sodium, lithium, potassium
No
Sodium and Potassium are stored in kerosene to protect them from rust since the are very reactive elements and react with Oxygen as soon as being exposed to it.
Solid fuel: coal, wood Liquid fuel: kerosine, gasoline Gas fuel: methane, hydrogen
Fossils can be preserved in either ice or snow, also can be preserved in mud, coal, sand, silt.

kerosine
Sodium metal reacts violently with water, and is stored in kerosine (for example) to avoid contact with moisture in the air.
Most common jet fuel is kerosine based and not corrosive.Most common jet fuel is kerosine based and not corrosive.
Kerosene
it is used for the fuel of planes
Depends on the kind of paint: oil based paint will dissolve in, or at least mix with kerosine, water based will not (e.g. alkyds)
Kerosine (Kerosene or Paraffin as it is more commonly known) can not be removed completely from stew, it's best throw the meal away.
kerosene is a chemical use for heat and oil
Kerosine, Varsol
try kerosine
wow your dad is a truly amazing pilot if he can use diesel...most jet's and planes use kerosine as a fuel, at least im sure it's kerosine :)
