Carbonyl fluoride, COF2, is an important intermediate used in the production of fluorine-containing compounds. For instance, it
Anna11 [10]

Answer:

[COF₂] = 0.346M

Explanation:

For the reaction:

2COF₂(g) ⇌ CO₂(g) + CF₄(g)

Kc = 5.70 is defined as:

Kc = [CO₂] [CF₄] / [COF₂]² = 5.70 <em>(1)</em>

Equilibrium concentrations of each compound after addition of 2.00M COF₂ will be:

[COF₂] : 2.00M - 2x

[CO₂] : x

[CF₄] : x

Replacing in (1):

5.70 =  [X] [X] / [2-2x]²

22.8 - 45.6x + 22.8x² = x²

0 = -21.8x² + 45.6x - 22.8

Solving for x:

X = 1.265 <em>-False answer, will produce negative concentrations-</em>

<em>X = 0.827.</em>

Replaing, molar concentration of COF₂ is:

[COF₂] : 2.00M - 2×0.827 = <em>0.346M</em>

I hope it helps!

Which of the following substances would complete a circuit and allow electricity to flow?
Elza [17]

The substances which allow the current to flow in the circuit are:  

Lithium bromide in a solution and Graphite.  

Lithium bromide can be pass the current in the circuit, due to the ability to form ions in the solution Li⁺ and Br⁻ which are mobile and can transport the electrical charge.

In the graphite because of the presence of delocalised electrons, each carbon atom forms three covalent bonds with three other carbon atoms, it conducts electrical current.

In the case of potassium chloride lattice there are in a solid form and the atoms are not mobile so they can not form ions.  In the diamond all the carbon valences are satisfied so the electrical charge can not be transported.

Nitric oxide in a solution is isolated and can not transport the electrical current due to its inability of the to form ions .

If I stretch a rubber band across the room you are transforming energy in to
mihalych1998 [28]
Hello!

When you're stretching a rubber band, you are giving the band potential energy, because when you stretch it out, you are getting energy ready for when you're going to release it, like energy waiting to be released.

Hope this helps! ☺♥
