Question

x plus yso4 gives xso4 plus y ;y plus xso4 gives no reaction out of the two element x and y which is more reactive and why

Answer 1

hey..!!
Here is ur answer...

X is more reactive here.
This is because X could displace the element y from its salt solution,which indicates that it is more reactive and the ion of element of X would be having lower reduction potential than that of ion of y.

Answer 2

Answer: X is more reactive than Y.

Explanation:

A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution.

$X+YSO_4\rightarrow XSO_4+Y$

As X can easily lose electrons as compared to Y and result in the formation of $XSO_4$ from $YSO_4$, thus X  is more reactive than Y.

$Y+XSO_4\rightarrow {\text {no reaction}}$

As Y is not able to displace X from its salt solution, it is less reactive than X.

Thus the answer is X is more reactive than Y.
