Answer to Question #129819 in Inorganic Chemistry for Morgan

Question

Hydrogen forms numerous hydrides with many elements of the periodic table.
a) give the formula of the stable hydride for each of the following elements: Li, Be, B, N, O and F.
b) Classify the hydrides in (a) as being predominantly ionic/ covalent
c) Give the reaction equation for a reaction between the hydride of Li and water

Answer 1

a) LiH , BeH₂ , BH₃ , NH₃ , H₂O, HF .

b) ionic hydride = LiH

Covalent hydride = BeH₂ , BH₃ , NH₃ , H₂O, HF .

C). LiH + H₂ O = LiOH + H₂ .
