Which of the following produced colourless gas with dil. H_(2)SO_(4) ?

Comment True (T) or False (F) for the following statements: (P) Same gas comes out when Na_(2)S is treated with dil HCI and Na_(2)SO_(3) is treated with (Zn+ dil H_(2)SO_(4)) . (Q) Same obervation when acidified nitrite solution is treated with urea or thiourea followed by addition of FeCI_(3) solution. (R) Same observation when nitrite solution or acetate solution is treated with dil. H_(2)SO_(4) solution. (S) With CaCI_(2) and BaCI_(2) both acetate and formate do not react.

2.616g of an element (X) is heated with excess of NaNO_(3) and NaOH to produce a basic gas (Y) and Na_(2)XO_(2) . The basic gas liberated exactly requires 5 xx 10^(-3) mol H_(2)SO_(4) for complete neutralisation. If 4 mol of X are completely consumed by caustic soda, find the no of mole of H_(2) gas liberated.
