Hemoglobin is an oxygen carrying protein. The correct statement about oxy-hemoglobin is that

If a mixture of NaCl, conc. $H_{2}S{O}_4$ and $K_{2}C{r}_2{O}_7$ is heated in a dry test tube, a red vapour (P) is formed. This vapour (P) dissolves in aqueous NaOH to form a yellow solution, which upon treatment with $AgN{O}_3$ forms a red solid (Q). P and Q are, respectively

For the following reaction

$2Mn{O}_4^{-}+5H_2{C}_2{O}_4+6H^{+}\to 2M{n}^{2+}+8H_{2}O+10C{O}_2$

$E^{\circ }(Mn{O}_4^{-}/M{n}^{2+})=+1.51V$ and $E^{\circ }(C{O}_2/H_2{C}_2{O}_4)=-0.49V$.

At 298 K, the equilibrium constant is

The ground states of high-spin octahedral and tetrahedral Co(II) complexes are, respectively
