Get started for freeWhen sodium reacts with hydrogen gas, sodium hydride is produced. Is sodium hydride an ionic or a covalent compound? When sodium hydride reacts with water, the equation is: $$ \mathrm{NaH}(s)+\mathrm{H}_{2} \mathrm{O}(l) \longrightarrow \mathrm{Na}^{+}(a q)+\mathrm{OH}^{-}(a q)+\mathrm{H}_{2}(g) $$ Show that this reaction can be considered both an oxidationreduction reaction and an acid-base reaction.
The compound with the formula TII_ is a black solid. Given the following standard reduction potentials, \(\mathrm{T} 1^{3+}+2 \mathrm{e}^{-} \longrightarrow \mathrm{Tl}^{+}\) \(\mathscr{E}^{\circ}=1.25 \mathrm{V}\) \(\mathrm{I}_{3}^{-}+2 \mathrm{e}^{-} \longrightarrow 3 \mathrm{I}^{-}\) \(\mathscr{E}^{\circ}=0.55 \mathrm{V}\)
Although the earth was formed from the same interstellar material as the sun, there is little elemental hydrogen \(\left(\mathrm{H}_{2}\right)\) in the earth's atmosphere. Explain.
