What are the products of the following reaction of strontium hydride and water? SrH₂(s) + H₂O(l) $\rightarrow$ A) Sr²⁺(aq) + H₂(g) + O₂(g) B) Sr²⁺(aq) + H₂(g) + OH¯(aq) C) Sr(s) + H₂(g) + OH¯(aq) D) Sr(s) + H₃O⁺(aq) E) None of these choices is correct.

Question

Quizplus · Accepted Answer

The reaction between strontium hydride and water will form strontium hydroxide (Sr(OH)2) and hydrogen gas (H2). The correct equation for this reaction is:
SrH2 + 2H2O → Sr(OH)2 + 2H2
In the given equation, SrHS is likely a typo for SrH2, and the products should be Sr(OH)2 and H2 gas. Choice B correctly includes SrS and OH¯(aq) as products, which represent Sr(OH)2 dissolved in water. The other choices either include incorrect products (such as Choice A) or are incomplete (such as Choice C, which is missing hydrogen gas as a product). Therefore, Choice B is the best choice.
