Textbook Question
Chapter 7, Problem 20Q
Potassium and lithium both are reactive Group 1 metals. Both form hydrides, highly reactive compounds.
- a. Potassium reacts with H2 to form potassium hydride, KH. Write the balanced chemical equation.
- b. KH reacts with water to produce H2 and potassium hydroxide. Write the balanced chemical equation.
- c. Offer a reason why LiH (rather than KH) has been proposed as a means of storing H2 for use in fuel cells.
