Which of the following reactions describes the formation of an ionic hydride? A)2H₂(g)+ O₂(g)→ 2H₂O(l) B)H₂(g)+ Cl₂(g)→ 2HCl(g) C)2K(s)+ H₂(g)→ 2KH(s) D)H₂(g)+ C₂H₄(g)→ C₂H₆(g) E)N₂(g)+ 3H₂(g)→ 2NH₃(g)

Question

Quizplus · Accepted Answer

An ionic hydride is formed by the reaction between a metal and hydrogen, resulting in the transfer of electrons from the metal to hydrogen, forming an ionic bond. Choice C shows the reaction between potassium, a metal, and hydrogen gas, indicating the formation of an ionic hydride (potassium hydride - KH). The other choices do not involve a metal and hydrogen reacting to form an ionic compound.
