Explanation:
<u>Step 1: Define</u>
Al₂(SO₃)₃ - Aluminum Sulfide
2Al₂(SO₃)₃
<u>Step 2: Identify</u>
In Aluminum Sulfide, we have 2 Al's for every 3 SO₃²⁻'s.
So far, we have 2 Al's in total.
BUT, since we have a 2 coefficient in 2Al₂(SO₃)₃, we need to multiply by 2.
Therefore, we have 4 Al's in total.
Answer:
Explanation:
Ba( OH)₂ + 2HCl = BaCl₂ + 2H₂O .
75.5 mL of 0.247 M barium hydroxide = .0755 x .247 = .01864 moles
95.0 mL of 0.330 M HCl = .095 x .33 = .03135 moles
mole ratio of hydrochloric acid to barium hydroxide
= .03135 / .01864 = 1.68
theoretical ratio = 2 /1 = 2
As the theoretical ratio is more , therefore HCl is the limiting reactant .
