Question

Freon, a very useful refrigerant, is produced in the following reaction:

Answer 1

Answer:

The chemistry will need 2*10⁶ moles of antimony trifluoride.

Explanation:

The balanced reaction is:

3 CCl₄ (g) + 2 SbF₃ (s) → 3 CCl₂F₂(g) + 2 SbCl₃ (s)

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of each compound participate in the reaction:

• CCl₄: 3 moles  
• SbF₃: 2 moles
• CCl₂F₂: 3 moles
• SbCl₃: 2 moles

You can apply the following rule of three: if by reaction stoichiometry 3 moles of freon are produced by 2 moles of antimony trifluoride, 3*10⁶ moles of Freon are produced from how many moles of antimony trifluoride?

$moles of antimony trifluoride=\frac{3*10^{6} moles of freon*2 moles of antimony trifluoride}{3 moles of freon}$

moles of antimony trifluoride= 2*10⁶

The chemistry will need 2*10⁶ moles of antimony trifluoride.
