Freon, a very useful refrigerant, is produced in the following reaction:
Svetach [21]

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

<u><em>The chemistry will need 2*10⁶ moles of antimony trifluoride.</em></u>

What is the ratio of carbon to oxygen in the following balanced equation: 2C + O2–&gt; 2CO
Morgarella [4.7K]

Answer:

The ratio is 2:1, that is 2mol C  / 1mol O2

Explanation:

First check to see if the equation is balanced. It is so now let's find the ratio.

The ratio is the stoichiomeric coefficient of the element or compound.

Carbon : Oxygen

2C : 1 O2   , so 2:1 ..

Why does hydrogen fluoride have a high boiling point
mezya [45]

The intermolecular bonding for HF is van der Waals, whereas for HCL, the intermolecular bonding is hydrogen. Since the van der Waals bond is stronger than hydrogen, HF will have a higher boiling temperature. Since the covalent bond is stronger than van der Waals, HF will have a higher boiling temperature.
