1. Write the balanced reaction of Al with CuCl2. 2. What is the limiting reagent if 0.5 g Al is reacted with 3.5 g CuCl2? (Reminder: CuCl2 is a dihydrate)

3. What is the theoretical yield of copper produced by the reaction above?

help plsss

1.

2. CuCl₂·2H₂O is limiting reactant.

Chemical reaction: 3CuCl₂·2H₂O + 2Al → 3Cu + 2AlCl₃ + 6H₂O. m(Al) = 0,5 g.

3. The molar mass of copper is 63.546 grams per mole.

If we multiply everything out, we'll get 0.50722 grams of copper, which is our theoretical yield.

Hope it helps uh :)♡~

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
