Part 2: Explain why aluminum (Al) would react with copper chloride (CuCl2) but not
with magnesium chloride (MgCl2).

Explanation:

Given species:

            Aluminum (Al)      and    CuCl₂

             Aluminum (Al)      and    MgCl₂

Aluminum would react with copper chloride because, aluminum is higher than copper in the activity series of metals. Due to this higher reactivity, it will displace copper from solution.

Magnesium is higher than Aluminum in the activity series. So, aluminum is less reactive compared to magnesium and so, it will not be able to displace it in the reaction.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
