How many moles of Cl2 can be produced from 5.60 mol HCl in reaction
HCl + O2 → Cl2 + H2O (unbalanced) (3 significant. final answer)
The balanced reaction is:4HCl + O2 → 2Cl2 + 2H2O.According to the reaction, n(Cl2) = 1/2 n(HCl) = 5.60/2 = 2.80 moles.Answer: 2.80 moles

4moles of an equimolar mixture of cl2and N2 are added to a vessel containing 1 mole of PCl5,2moles of PCl3,and 3 moles of Cl2 at equilibrium,the mole fraction of PCl5 at equilibrium will be?
Cl2 + PCl3 = PCl52 mol Cl2 + 2 mol PCl3 = 2 mol PCl5So, finalCl2 = 3 mol;N2 = 2 mol;PCl3 = 0 mol;PCl5 = 3 molTotal = 8...

2Na+Cl2→2NaCl When 10.0 g of Cl2 is used, the reaction produced 12.5 grams NaCl. What is the % yield of the reaction? Use the following molar masses: Cl2=70g/mol and NaCl=58g/mol.
2Na + Cl2 → 2NaClThe theoretical yield of the reaction:m(NaCl) = m(Cl2) × 2 Mr(NaCl) / Mr(Cl2) = 10.0 g × 2 × 58 g/mol / 70 g/mol = 16.6...

According to the reaction H₂ + Cl₂ → 2HCl the production of 2.0 moles of HCl would require 70. grams of Cl₂. How many grams of H₂ would be needed?
By stoichiometry, you would need 1 mole of H2 to produce 2.0 moles of HClSo you would need (1.0 moles)(2.0 g / mole H2) = 2.0 g

For the reaction
?Al+?Cl2 →?AlCl3 ,
what is the maximum amount of AlCl3 which could be formed from 6 mol of Al and 7.88 mol of Cl2?
Answer in units of g.
The equation is2Al + 3Cl2 = 2AlCl3Chlorine is the limiting reactant, that's why the calculations of the formed product will be performed using the quantity of Cl2n(Cl2) = 7.88 moln(AlCl3)...
