When CuCl2 (Copper Chloride,) a solid powder, is reacted with Aluminum (Al), a solid, in a solution, what would you expect to be left in the vial? Hint: A single replacement reaction should happen. Select one:
a. Oxygen
b. Pure Aluminum
c. Carbon Dioxide
d. Pure copper

D pure copper

Explanation:

This also is associated with the electrochemical series

AL is more reactive than copper and it will be displaced out of the solution. Leaving Copper to be left as a solid in the reaction.

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .
