The quantity of the cobalt ore [Co\(_3\)(AsO\(_4\))\(_2\)\( \cdot \) H\(_2\)O] required to obtain 1 kg of cobalt (rounded off to two decimal places) is \(\underline{\hspace{2cm}}\) kg.
Given: Atomic Wt. of Co = 59, As = 75, O = 16, H = 1.
The reaction
\[ \text{CO} (g) + \text{Cl}_2 (g) \rightleftharpoons \text{COCl}_2 (g) \] at 500 °C, with initial pressures of 0.7 bar of CO and 1.0 bar of Cl_2, is allowed to reach equilibrium. The partial pressure of COCl_2 (g) at equilibrium is 0.15 bar. The equilibrium constant for this reaction at 500 °C (rounded off to two decimal places) is \(\underline{\hspace{2cm}}\).
The correct statement(s) about the concentration of Na\(^+\) and K\(^+\) ions in animal cells is/are:
Hexane and heptane are completely miscible. At 25°C, the vapor pressures of hexane and heptane are 0.198 atm and 0.06 atm, respectively. The mole fractions of hexane and heptane in the vapor phase for a solution containing 4 M hexane and 6 M heptane, respectively, are:
The shapes of the compounds ClF\(_3\), XeOF\(_2\), N\(_3^-\) and XeO\(_3\)F\(_2\) respectively, are:
