Prince Khan 7 years, 11 months ago

The sum of the oxidation states of all the atoms or ions in a neutral compound is zero. The sum of the oxidation states of all the atoms in an ion is equal to the charge on the ion. The more electronegative element in a substance is given a negative oxidation state.

Which metal is kept in kerosene

Posted by Neha Bano 7 years, 11 months ago

Shruti Krishna 7 years, 11 months ago

As meytal such as potassium are so highly reactive that on coming in contact with air, immediately it catches Fire, hence they are kept under kerosene.

0Thank You

Prince Khan 7 years, 11 months ago

Sodium is a very reactive metal. It is kept in kerosene to prevent it from coming in contact with oxygen and moisture. If this happens, it will react with the moisture present in air and form sodium hydroxide. This is a strongly exothermic reaction, and lot of heat is generated.
