The K sp for barium fluoride, BaF2, is 2.45 × 10-5. What is the molar solubility of barium fluoride?

lilavasa [31]

Answer: The molar solubility of barium fluoride is 0.0183 moles/liter.

Explanation:

The equation for the reaction will be as follows:

$BaF_2\rightarrow Ba^{2+}+2F^$

By Stoichiometry,

1 mole of $BaF_2$ gives 2 moles of $F^-$ and 1 mole of $Ba^{2+}$

Thus if solubility of $BaF_2$ is s moles/liter, solubility of $Ba^{2+}$ is s moles/liter and solubility of $F^-$ is 2s moles/liter

Therefore,

$K_sp=[Ba^{2+}][F^{-}]^2$

$2.45\times 10^{-5}=[s][2s]^2$

$4s^3=2.45\times 10^{-5}$

$s^3=6.12\times 10^{-6}moles/liter$

$s=0.0183moles/liter$

Thus the molar solubility of barium fluoride is 0.0183 moles/liter.

Consider the following element combinations. Classify the bonds formed between each pair as ionic, polar covalent, or nonpolar c

Sati [7]

An ionic bond is formed by the transfer of electrons from one atom to the other. It is usually formed between a metal + non-metal.

A covalent bond is formed by sharing of electrons between two atoms. It is formed between two nonmetals. A polar covalent bond is formed between 2 non-metals which differ in their electronegativities. In contrast, in a non-polar covalent interaction the two atoms could either be the same or have very close electronegativities.

1) P and I : Both non-metals with different electronegativities= Polar Covalent

2) Fe and O: Metal + non-metal = Ionic

3) S and Cl: Both non-metals with different electronegativities= Polar Covalent

4) S and S: Both non-metals and the same atoms = Non-polar Covalent

5) Br and Br: Both non-metals and the same atoms = Non-polar Covalent

6) O and Cl: Both non-metals with different electronegativities= Polar Covalent

7) Be and Cl: Metal + non-metal = Ionic

8) Al and N: Metal + non-metal = Ionic

A sample of gas has an initial volume of 22.6 L at a pressure of 1.67 atm. If the sample is compressed to a volume of 10.0 L : ,

Sphinxa [80]

Answer:

3.74 atmospheres

Explanation:

If the temperature is constant, then the formula is

V*P = V1 * P1

V = 22.6 L

P = 1.67 atm

V1 = 10.0 L

P1 = ??

=============

22.6 * 1.67 = 10 * P1

37.742 = 10 * P1

37.742/10 = P1

P1 = 3.742

Note there are 3 sig digs in each given, so the answer should be

P1 = 3.74 atmospheres

What is the molar concentration of a solution prepared by dissolving 8.63 g of Ba(NO3)2 (molar mass = 261.35 g/mol) to a total v

antiseptic1488 [7]

The concentration of the solution is 0.132 M, the concentration of the diluted solution is 0.026 M.

Given that;

number of moles = concentration × Volume

Concentration = number of moles/volume

But number of moles = mass/molar mass

mass = 8.63 g

Molar mass = 261.35 g/mol

Hence, number of moles = 8.63 g/261.35 g/mol = 0.033 moles

volume = 250.0 mL or 0.25 L

concentration = 0.033 moles/0.25 L = 0.132 M

For the second part of the question;

Using the dilution formula, C1V1 =C2V2

C1 = initial concentration = 0.132 M

V1 = initial volume = 10.0 mL

C2 = Final concentration = ?

V2 = Final volume = 50.00 mL

C2 = 0.132 M × 10.0 mL/ 50.00 mL

C2 = 0.026 M
