An element 'X', in which the difference in electrons present in valence shell and penultimate shell is equal to the number of electrons present in first shell, undergoes combustion to produce 'Y'. 'Y' turns lime water milky due to theformation of 'Z'.Identify 'X','Y' and'Z'.

1.	An element 'X', in which the difference in electrons present in valence shell and penultimate shell is equal to the number of electrons present in first shell, undergoes combustion to produce 'Y'. 'Y' turns lime water milky due to theformation of 'Z'.Identify 'X','Y' and'Z'.
Answer» `C,CO_(2),CaCO_(3)` `S,SO_(2),CaSO_(3)` `S,SO_(2),Ca(HSO_(3))_(2)` `C,CO_(2),Ca(HCO_(3))_(2)` Solution :ELECTRONIC confifuration X is of 2, 8, 6. Hence X is sulphur `underset((X))(S+O_(2))tounderset((Y))(SO_(2))` `underset((Y))(SO_(2))+Ca(OH)_(2)tounderset(("MILKY white"))underset((Z))(CaSO_(3)darr+H_(2)O)`
