Element A burns innitrogento give an ions compound B reactswith water to give C and D .Asolution of chemes ''milky'' on bubbling carbon dioxide identify A,B,C and D

Answer»

SOLUTION :The gives DATE SUGGEST the following reactions
`underset((A))(3Ca) +N_(2) rarr underset((B))(Ca_(3)N_(2))`
`ca_(3)N_(2) + 6H_(2)O rarrunderset((C))( 3Ca(OH)_(2)) + underset((D)) (2NH_(3))`
`underset((E))(Ca(OH)_(2)) +CO_(2) rarr CaCO_(3) +H_(2)O`
It is giventhat a solution of C Become 'milk'` on bubblingcarbon dioxide .Therefore it must becalciumor bariumhydroxidewhich is morethanmagnessiumhydroxide.
