Vedclass · Answer

(C) Let us analyze the reactions with water for each pair:$1$. For $Na_2O$ and $Na$:$Na_2O + H_2O \rightarrow 2NaOH$$2Na + 2H_2O \rightarrow 2NaOH + H_2(g)$The products are different ($H_2$ gas is produced in the second reaction but not the first).$2$. For $CO_2$ and $K_2O$:$CO_2 + H_2O \rightarrow H_2CO_3$$K_2O + H_2O \rightarrow 2KOH$The products are different.$3$. For $Na$ and $NaH$:$2Na + 2H_2O \rightarrow 2NaOH + H_2(g)$$NaH + H_2O \rightarrow NaOH + H_2(g)$Both reactions produce $NaOH$ and $H_2$ gas as products. Therefore,this pair produces the same products.

Which of the following pairs will produce the same products upon reaction with water?
