Correct Answer - C
S-1:It lowers the fusion temperature of `MgCl_2` and provide conductivity to the elecrolyte.
S-2: `MgCl_2. 6H_2O` is calcined in a stream of dry HCl gas to have anhydrous `MgCl_2` . In absence of dry HCl. It forms `Mg_2OCl_2 (MgO. MgCl_2)` because of hydrolysis .

Sodium chloride contains 60.68% chlorine by mass. If 7.1 g chlorine is made to react with 5.2 g of sodium, the number of moles of sodium which reacted

Correct Answer - A Percentage of sodium `= 100 -60.68 = 39.32` 60.68 chlorine react with sodium = 39.32 g 7.1 g of chlorine react with sodium `= ((39.32g)xx(7.1g))/(60.68)` `= 4.60...
