Calcium burns in nitrogen a white solid which sufficient water to prod

1.	Calcium burns in nitrogen a white solid which sufficient water to produce a gas (A) and an alkaline solution. The solution o nexposure to air produces a solid layer of (B) on the surface. Identify the compound (A) and (B).
Answer» Solution :The chemical reaction involved as follows: `3Ca+N_(2) OVERSET("Heat")to underset("Cal.Nitrite")(Ca_(3)N_(2)),+6H_(2)O to underset("ALKALINE")(3Ca(OH)_(2))+underset(A)(2NH_(3))` `CA(OH)_(2)+CO_(2)("air")to underset("Cal. carbonate")(CaCO_(3))+underset(A)(H_(2)O)`
