Explain why aluminum (al) would react with copper chloride (cucl2) but not with magnesium chloride (mgcl2).

Explanation:

According to the reactivity series, magnesium is a more reactive element than aluminium.

For example,

So, when aluminium metal is added in magnesium chloride then there will be no reaction.

As being less strong aluminium is unable to displace magnesium from magnesium chloride.

On the other hand, aluminium metal being more reactive than copper is able to displace copper from .

For example,

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"

by the combination of an unlimited number of elements
