A major challenge in implementing the “hydrogen economy”
Chapter , Problem 88AE(choose chapter or problem)
A major challenge in implementing the “hydrogen economy” is finding a safe, lightweight, and compact way of storing hydrogen for use as a fuel. The hydrides of light metals are attractive for hydrogen storage because they can store a high weight percentage of hydrogen in a small volume. For example, can release 5.6% of its mass as upon decomposing to NaH(s), Al(s), and . possesses both covalent bonds, which hold polyatomic anions together, and ionic bonds.
(a) Write a balanced equation for the decomposition of . (b) Which element in is the most electronegative? Which one is the least electronegative? (c) Based on electronegativity differences, predict the identity of the polyatomic anion. Draw a Lewis structure for this ion. (d) What is the formal charge on hydrogen in the polyatomic ion?
