When `SnCl_(2)` is treated with `HgCl_(2)`, the products formed are

Correct Answer - C `SnCl_(2)` is reducing agent and reduces `Hg^(2+)` to `Hg_(2)^(2+)` and itself oxidised to `Sn^(4+)`.

One mole of aqueous solution of the complex `CoCl_(3)5H_(2)O` when treated with excess of aqueous `AgNO_(3)` solution gave one mole of white pptof AgC

The data shows that one Cl atoms is not inovlved in the co-oridnation sphere and is present in the ionisation sphere as `Cl^(-)` ion. Therefore, the formula of the complex...

Calculate the number of atom in each of the following (Given : Atomic mass of I = 127 u). a. 254 u of iodine (I) b. 254 g of iodine (I)

(a). 254 u of iodine (I) = x atoms  Atomic mass of iodine (I) = 127 u  ∴ Mass of one iodine atom = 127 u ∴ x = \(\frac{254u}{127u}\) = 2 atoms (b). 254 g...
