Balance the chemical equation for the important industrial process: C2H4 + O2 + HCl → C2H4Cl2 + H2O.

Given 610.0 kg of hydrochloric acid, calculate how many kg of C2H4Cl2 can be produced.

• Chem -

2C2H4 + O2 + 4HCl ==> 2C2H4Cl2 + 2H2O

mols HCl = 610,000/molar mass = ?
Convert mols HCl to mols product using the coefficients in the balanced equation. ?mol HCl x (2 mol C2H4Cl2/4 mols HCl) = ? mols HCl x 1/2 = x mol C2H4Cl2.
Now convert mols C2H4Cl2 to grams. g = mols x molar mass C2H4Cl2.
