Rewrite the equation of Problem 15.103 using dot diagrams, and show with an arrow the proton being transferred. Note that H^– is an H with a lone pair of electrons on it.

Data from Problem 15.103

Hydride ion, H^–, is an exceptionally strong base, reacting with water to produce lots of hydroxide ion and H₂ gas. The K_eq for this reaction is huge.

Write the balanced equation for the reaction between hydride and water.

Explain why H₂ gas forms.
