Consider the following statements. (a) BeO is amphoteric in nature. (b) is not found in solid state. (c) is diamagnetic but is paramagnetic. (d) White phosphorous react with castic soda and gives phosphine gas. (e) is soluble in excess of and form sodium meta aluminate. (f) Anhydrous potassium nitrate on strong heating gives potassium oxide, nitrogen and oxygen gas. (g) exist in solid form. (h) Hydrated magnesium chloride on heating in dry air gives anhydrous .
If correct statements are 'X' & incorrect statements are 'Y' then find the value of
Answer:
Solution:
Correct statements (X): Statements (a), (b), (c), (d), (e), (f), and (g) are all true, so .
Incorrect statements (Y): Only statement (h) is false because heating MgCl₂·6H₂O causes hydrolysis to form MgO and HCl instead of anhydrous MgCl₂, so . Calculation:
