Question

what type of chemical reaction is shown: $ce{h_{2}so_{4} + 2 nacn -> 2 hcn + na_{2}so_{4}}$synthesissingle replacementdecompostiondouble replacement

Explanation:

This reaction involves two ionic compounds ($\text{H}_2\text{SO}_4$ and $\text{NaCN}$) swapping their positive and negative ions: the hydrogen ($\text{H}^+$) from sulfuric acid pairs with cyanide ($\text{CN}^-$) to form $\text{HCN}$, and sodium ($\text{Na}^+$) pairs with sulfate ($\text{SO}_4^{2-}$) to form $\text{Na}_2\text{SO}_4$. This matches the definition of a double replacement reaction.

Answer:

Double Replacement
