Over coffee and croissants at breakfast one day, your friend Rita (an expert chemist) says this: "group 2a metal hydrides react with water to produce hydroxides and hydrogen gas." using Rita's statement, and what you already know about chemistry, predict the products of the following reaction. be sure your chemical equation is balanced!
Accepted Answer
The reaction of a Group 2A metal hydride with water will produce a metal hydroxide and hydrogen gas. For example, the reaction of calcium hydride (CaH₂) with water (H₂O) will produce calcium hydroxide (Ca(OH)₂) and hydrogen gas (H₂):
CaH₂(s) + 2H₂O(l) → Ca(OH)₂(aq) + 2H₂(g)
