Equation Unbalanced : __AlCl3 + __F2 --> __AlF3 + __Cl2
When 4.00g of flourine reacts with excess aluminum chloride, how many grams of chlorine gas are produced? First balance the equation.

Respuesta :

[tex]\\ \rm\Rrightarrow 2AlCl_3+3F_2\longrightarrow 2AlF_3+3Cl_2[/tex]

  • Balanced

3mols of fluorine produce 2 mol chlorine

1 mol fluorine produces 2/3=0.6mol chlorine

Moles of fluorine gas=

  • 4/19
  • 0.2mol.approx

Moles of chlorine:-

  • 0.2(0.6)=0.18mol

Mass of chlorine

  • 71(0.18)
  • 12.78g
