Metal M reacts with water to form a compound S and gas G . The solution S turns red litmus to blue whereas gas G , which is lighter than air and burns with pop sound metal M has low melting point and in kept in kerosene?
Identify the metal M and compound S write their chemical name and chemical formula.
What is nature of compound.
Write a balanced chemical equation for this?
Why metal M cannot be kept in water/

The metal M is Sodium(Na) and the compound formed is Sodium Hydroxide (NaOH). The nature of this compound is basic as it gives OH^- ions and that's why it turns red litmus into blue. The balanced chemical equation is :
2Na(s)+2H2O-> 2NaOH(l)+H2(g)
Sodium +Water -> sodium hydroxide + Hydrogen gas
Being a highly reactive metal Sodium is kept in kerosene oil as it react fastly with water. That's why it is not kept in water as an explosion may take place if we do so.
I hope that this may be helpful to you.
