A metal (M) produces a gas( N) on reacting with alkalies like NaOH and KOH. Same gas is produced when the metal reacts with dilute sulphuric acid. Gas(N) reacts with another toxic gas (P) to form methonol at high temperature and pressure. (N) also reacts with metals like (Q) to form electrovalent hydrides. Identify M,N,N and Q.

1.	A metal (M) produces a gas( N) on reacting with alkalies like NaOH and KOH. Same gas is produced when the metal reacts with dilute sulphuric acid. Gas(N) reacts with another toxic gas (P) to form methonol at high temperature and pressure. (N) also reacts with metals like (Q) to form electrovalent hydrides. Identify M,N,N and Q.
