Select the correct choice for given reactions: (i) 2Na +2H_(2)O to X (ii) 2F_(2)+2H_(2)O to Y (iii) H_(2)S +2H_(2)O to Z

Select the correct choice for given reactions: (i) 2Na +2H_(2)O to X

1.	Select the correct choice for given reactions: (i) 2Na +2H_(2)O to X (ii) 2F_(2)+2H_(2)O to Y (iii) H_(2)S +2H_(2)O to Z
Answer» `X=2Na_(2)+H_(2)` `Y=4OH^(-)+4F^(-)+O_(2)` `Z=HS^(-) +H_(3)O^(+)` `X=2NaOH+H_(2)` `Y=4H_(3)O^(+)+4F^(-)` `Z=S^(2-)HS^(-)` `X=2Na_(2)O_(2)+H_(2)` `Y=4H_(3)O^(+)+4F^(-)+O_(2)` `Z=2H_(3)O^(+)+HS^(-)` `X=2NaOH+H_(2)` `Y=4H^(+)+4F^(-)+O_(2)` `Z=2H_(3)O^(+)+S^(2-)` Solution :(i) `2Na+2H_(2)O to UNDERSET(X)ubrace(2NaOH+H_(2))` (ii) `2F_(2)+2H_(2)O to underset(Y) ubrace(4H^(+)+4F^(-)+O_(2))` (III) `H_(2)S+2H_(2)O to underset(Z) ubrace(2H_(3)O^(+)+S^(2-))`
