How many of the following statements are correct ? (a)BeO is amphoter

1.	How many of the following statements are correct ? (a)BeO is amphoteric in nature ltbgt (b)LiHCO_3 is not found in solid state. ( c)K_2O_2 is diamagnetic but KO_2 is paramagnetic (d)Hydrated magnesium chloride on heating in dry air gives anhydrous MgCl_2 (e)AlCl_3 is soluble in excess of NaOH and form sodium meta aluminate (f)Anhydrous potassium nitrate on heating with potassium metal gives potassium oxide and nitrogen gas (g)Lithium chloride is highly soluble in water.
Answer» SOLUTION :(a),(b), (E) & (f) are correct. (b)`LiHCO_3oversetDeltatoLi_2CO_3+H_2O+CO_2` (d)`MgCl_2 . 6H_2O to MgO+HCl+H_2O` (e)`AlCl_3+4NaOH("EXCESS")to NaAlO_2+2H_2O+3NaCl` (f)`KNO_3+K to K_2O+N_2`
