✔ 最佳答案
From the description copper and hydrogen are both being displaced by metal Y, so Y has to be some metal higher in the activity series than hydrogen, and supposing this reaction took place at room temperature, the metal would have to be sodium or a metal higher than sodium in the activity series.
