Iron fluoride (FeF2) dissociates according to the following equation: FeF2(s) ⇌ Fe2+(aq) + 2 F–(aq) A sample of iron fluoride (F

eF2) is dissolved in water, and a saturated solution is obtained. The [Fe2+] is measured to be 2.05 × 10–4 mol/L. What is the concentration of fluoride (F–) ions?

Answer:

4.1 x 10^-4 mol/L

Explanation:

For the equation

FeF2(s)  --> Fe2+(aq) + 2F- (aq)

We have that for every mole of FeF2 we have a mole of Fe2+ and 2 moles of F-

FeF2(s)  --> Fe2+(aq) + 2F- (aq)

   1                  1                 2

If we have 2.05 x 10^-4 moles of Fe2+

FeF2(s)  --> Fe2+(aq) +      2F- (aq)

                2.05 x 10^-4         2 x 2.05 x 10^-4  

2 x 2.05 X 10^-4 = 5.1 x 10^-4 moles

So if in the solution is measured 2.05 x 10^-4 mol/L of [Fe2+] we have 5.1 x 10^-4 mol/L of [F-]

What kind of intermolecular forces act between two ammonia molecules
iragen [17]

Answer:

extensive hydrogen bonding

Explanation:

The high boiling points of water, hydrogen fluoride (HF) and ammonia (NH3) is an effect of the extensive hydrogen bonding between the molecules. The London dispersion force is caused by random and temporary changes in the polarity of atoms, caused by the location of the electrons in the atoms' orbitals.

Hope this helps :)
