- Now lets calculate how many moles of NH₄Cl will react with 2.49 mol Al (NO₂) ₃: (3 mol NH₄Cl / 1 mol Al (NO₂) ₃) x 2.49 mol Al (NO₂) ₃ = 7.5 mol NH₄Cl We only have 3.26 mol NH₄Cl.
- Nov 04, 2010 · 71g= 1 mole of Cl2. 23g= 23/71 = 0.324 moles of Cl2. The ratio of the no of moles of Cl2 that reacts to the no of moles of AlCl3 formed= 3:2. Therefore, the no of moles of AlCl3 produced= 2/3(no of moles of Cl2 that reacts) = 2/3(0.324) = 0.216. I hope this helps and feel free to send me an e-mail if you have any doubts!

where n is the moles of aluminum, k is the moles of sulfate, m is the moles of chloride, x is the moles of alkali metal or alkali earth metal and Z is the valence of the metal (e.g., 1 for Na + and 2 for Ca 2+). The basicity of the product is typically adjusted in order to account for desired stability, performance, and/or other product ... 2 days ago · When Aluminum is added to Copper Sulfate, it displaces Copper, and it reacts with Sulfate to for Aluminum Sulfate because Aluminum is more reactive than copper. The balanced equation is written as: 2Al + 3CuSO4 --> Al2(So4)3 + 3Cu. An oxidation-reduction reaction occurs where there is a transfer of elections from Aluminum to oxide Copper. 155 molecules of aluminum chloride will form. Check Your Solution The units are correct.
