The concentration of Ag+ ions in a saturated solution of Ag2C2O4 is 2.2 × 10–4 mol L–1.
The solubility product of Ag2C2O4 is:
| 1. | 2.66×10–12 | 2. | 4.5×10–11 |
| 3. | 5.3×10–12 | 4. | 2.42×10–8 |
In the electrochemical cell:
\(\mathrm{Z n \left|\right. Z n S O_{4} \left(\right. 0 . 01 M \left.\right) \left|\right. \left|\right. C u S O_{4} \left(\right. 1 . 0 M \left.\right) \left|\right. C u}, \)
the emf of this Daniel cell is E1. When the concentration of ZnSO4 is changed to 1.0 M and that of CuSO4 is changed to 0.01 M, the emf changes to E2. From the following, which one is the relationship between E1 and E2 ?
(Given, \(\frac{RT}{F}\) = 0.059)
1. \(\mathrm{E_{1} < E_{2}}\)
2. \(\mathrm{E_{1} > E_{2}}\)
3. \(\mathrm{E_{2} = 0 \neq E_{1}}\)
4. \(\mathrm{E_{1} = E_{2}}\)

Incorrect statement among the following is:
| 1. | The uncertainty principle is\(\Delta x \cdot \Delta p \geq \dfrac{h}{4 \pi} \) |
| 2. | Half-filled and fully filled orbitals have greater stability due to greater exchange energy, greater symmetry, and a more balanced arrangement. |
| 3. | The energy of the 2s orbital is less than the energy of the 2p orbital in the case of hydrogen-like atoms. |
| 4. | De-Broglie's wavelength is given by\(\lambda=\dfrac{h}{m v} \), where m= mass of the particle, v = group velocity of the particle. |
The incorrect statement among the following is -
| 1. | Density decreases in case of crystals with Schottky's defect. |
| 2. | NaCl(s) is insulator, silicon is semiconductor, silver is conductor, quartz is piezo electric crystal. |
