Calcium on heating in `N_2` yields an ionic compound A, which reacts with water to give
`Ca(OH)_2` and a gas B. Identify A and B

An element 'A' burns in nitrogen to give an ionic compound 'B' which reacts with water to give 'C' and D. 'E' is used in white washing. Identify, A, B, C and D:

Element 'A' burns in nitrogen to give an ionic compound 'B' which reacts with water to give 'C' and 'D'. The solution of 'C' becomes milky on bubbling carbon dioxide gas. Identify the compounds A, B, C and D.

Element A burns in nitrogen to give an ionic compound B. Compound B reacts with water to give C and D. A solution to C becomes milky on bubbling carbon dioxide. Identify A,B,C and D.

An element A reacts with water to form a compound B which is used in white washing. The compound B on heating forms an oxide C which on treatment with water gives back B. Identify A, B and C and give the reactions involved.
