Magnesium on heating separately with aqueousferric chloride and ammonium chloride gives the same gas, X,X is inflammable and reacts with metal to form electrovalent soild ,which on hydrolysis gives the same gas .Predict the gas X.

Magnesium on heating separately with aqueousferric chloride and ammoni

1.	Magnesium on heating separately with aqueousferric chloride and ammonium chloride gives the same gas, X,X is inflammable and reacts with metal to form electrovalent soild ,which on hydrolysis gives the same gas .Predict the gas X.
Answer» Solution :The gas .X. is hydrogen .Magnesium liberates hydrogen on reaction with aqueous ferric chloride `3Mg +2FeCl_(3)+6H_(2)O to 2MgCl_(2)+2Fe(OH)_(3)+3H_(2)` `MG+2NH_(4)CL to MgCl_(2)+2NH_(3)+H_(2)` The ELECTROVALENT solid is magnesium hydride , which gives hydrgen on hydrolysis . `Mg+H_(2) to MgH_(2)` `gH_(2+2H_(2)O to Mg(OH)_(2)+2H_(2)`
