Class 10 Question. Answer to Question. Ashish Raj Sep 15, Sodium immersed in kerosene oil because sodium is a reactive element that can burn in air. Upvote 8. Bipul Raj Feb 11, Because it's highly reactive metal Upvote 5.
Shashthi Mishra Sep 14, As sodium is the highly reactive element and when it come in contact with air it burns vigorously in air as it was an highly exothermic reaction.
Vidhi Chaturvedi Feb 11, Because it is highly reactive. Upvote 4. Tanishka Gupta Sep 15, Sodium metal is kept immersed in kerosene oil to prevent accidental fire. It is very reactive metal and combines explosively with air as well as water. It will catch fire if kept in open. Note: Potassium is also kept immersed in kerosene oil for same reason. Satish Agrawal Sep 09, When sodium is react with oxygen are vigorously catch fire.
Upvote 3. Vansh Aggarwal Sep 14, Sodium is highly reactive and reacts with air. Ankit Jaiswal Feb 12, Sodium is very reactive metal.
Sodium react with oxygen to form sodium hydroxide which is strongly exothermic reaction and during this reaction a lot of heat is generated. Upvote 1. Vishal Jadoun Feb 12, Because sodium is a very highly reactive metal and when exposed to air it vigorously react with air to fom its oxide.
Bharat Raj Feb 11, Bcoz it is a high reactive metaldue to its monovalency so it looses electron easily even in open air and react with oxygen to form Na2O, NaO for stable. Sameer Shrinath Sep 15, To cut oxygen supply as it can get its ignition temperature at normal room temp. Aditya Nandan Sep 15, Because sodium is very reaction which catches fire when it come in contact of air so it kept immersed in kerosene. Rahul Patwal Feb 12, It is very reactive it reacts with oyygen even in room temperature.
Chirag Aggarwal Feb 12, Explain the meanings of malleable and ductile. Write equations for the reactions of iron with steam. Samples of four metals A, B, C and D were taken and added to the following solution one by one. The results obtained have been tabulated as follows : Use the table above to answer the following questions about metals A, B, C and D. Which is the most reactive metal? What would you observe if B is added to a solution of Copper II sulphate?
Arrange the metals A, B, C and D in the order of reactivity. Which gas is produced when dilute hydrochloric acid is added to a reactive metal? What would you observe when zinc is added to a solution of iron II sulphate? Write the chemical reaction that takes place.
Write the electron-dot structures for sodium, oxygen and magnesium. What are the ions present in these compounds?
