In human body A is a pumping organ from lungs blood vessel B with oxygenated blood enters upper C part of left chamber of the organ. When "C" chamber contracts blood flows into "D" lower left chamber. "D" chamber contracts blood is pumped to all parts of the body except lungs through blood vessel E. Deoxygenated blood from body parts is collected by blood vessel "F " and opens upper "G" right chamber. This chamber contracts blood flows into "H" lower chamber.

  • (i) A white solid A, on being strongly heated, leaves a residue which is yellow while hot and white hot and white when cold ii) The solid A, insoluble in water, dissolves in dilute HCI to give a solution B and a gas which does nor affect acidified dichromate paper but turns baryta water milky. iii) When H_(2)S is passed through the solution B, a white precipitate C is obtained iv) The precipitate C dissolves in dilute HCI to give a solution which, when treated with an NaOH solution, gives a white precipitate. The final precipitate dissolves in an excess of NaoH form a solution D. This alkaline solution, on acidification with acetic acid followed by treatment with H_(2)S , gives the precipitate C. Given that the formation of the precipitate C from the solution D involves the reaction [M(OH)_(4)]^(2-)+4H^(+) to underset(underset(MS darr)(darr H_(2)S))(M^(2+))+4H_(2)O M is
