Question

What happens when zinc dust is added to a solution of mgcl2?

Answer 1

Answer:

Nothing would happens because Magnesium is more reactive than zinc so it can't displace Magnesium from its salt solution

Answer 2

No reaction happens when zinc dust is added to a solution of $MgCl_2$

Explanation:

A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution. Thus one element should be different from another element.

A general single displacement reaction can be represented as :

$XY+Z\rightarrow XZ+Y$

When zinc dust is added to $MgCl_2$, zinc being less reactive than magnesium wont be able to displace magnesium and hence no reaction will occur.
