Answer:

Aluminum is limiting reactant

Explanation:

Data Given:

Amount aluminum metal (Al) = 1.5 mole

chlorine gas (Cl₂) = 3 mole

limiting reactant = ?

Solution:

limiting reactant: The amount of reactant that consume first in a reaction is termed as limiting reagent or limiting reactant.

Excess reagent: the amount of reactant that remain unreacted at the end of the reaction is termed as excess reagent.

Now to look for the limiting regent we have to look at reaction

Reaction:

           2 Al + 3 Cl₂  --------> 2 AlCl₃

from this balance reaction we come to know that 2 mole of Aluminum metal react with 3 mole of chlorine gas. It means that amount of aluminum is less and it will consume first and act as limiting reactant.

To know with how much chlorine gas it will react apply unity formula

                2 mole of Al ≅ 3 mole of Cl₂

               1.5 mole of Al ≅ X mole of Cl₂

So,

                mole of Cl₂ =   3 mole x  1.5 mole / 2 mol

                mole of Cl₂ =   2.25 mol

So, 1.5 mol Aluminum consumed fully and react with 2.25 mol of Chlorine and 0.75 mol remain unreacted.

Aluminum is limiting reactant.

iren [92.7K]

Answer:

I just did the assignment it's "decreases"

Explanation:

If you guys came from Ed-genuity (i'm writing it like that because apperantly that is a swear word?) That means the next questions are "As you move from left to right across the periodic table, electronegativity..." and "As you move from top to bottom within a group, the first ionization energy...".

for electronegativity, it's increases and for ionization energy it's decreases. Hope this helps!
