JJ Thomson discovered the electron :)
Answer:
2Al(s) + 6HCl(aq)→2AlCl3(aq) + 3H2(g)
This is because of the increasing number of protons in the nucleus, resulting in a stronger attraction of the electrons with the nucleus.
The keyword here is gas condenses to a liquid, which mean we're talking about condensation process
The enthalpy energy in condensation process is negative because it releases energy
The entropy in general will also decreases .
Temperature affect this change because it will create free energy if added with this result
hope this helps
